NOTE
2. Installation
2.1 Power Sources
The latitude, longitude, and altitude of your site is entered into
the location area when setting up the station in Weather Station
software. A GPS unit, Google Earth or NOAA web sites can
help provide this information. This information is used in the
formula by the software to calculate Evapotranspiration.
x TurfWeather Site Installation Guide
x Campbell Scientific customer support 435-752-2342
This guide includes procedures for installing your TurfWeather weather station
on a tripod or pole and for installing our associated mounting/installation kits
as required. Before installing your weather station at your site, read over the
sections on power sources, site selection, and communications considerations.
The installation procedures start in Section 2.4.
TurfWeather weather stations are provided with an internal sealed rechargeable
lead acid battery that must be recharged to assure continued system function.
For recharging the battery, Campbell Scientific offers solar panels or an
AC/DC converter (see Appendix A: TurfWeather Equipment). If no power
supply has been ordered, you must provide an external DC power source that
has an output rating of 18 V.
CAUTION
Connecting an incompatible power source to your weather
station voids your Warranty. It is advisable for you to
check with your local distributor before connecting a power
source not purchased with weather station.
2.2 Site Selection
The ideal weather station site is level and well away from obstructions such as
buildings, trees, and steep slopes. If obstructions exist, use the “Ten Times the
Height Rule”, which is illustrated in Figure 2-1 below.
16
Page 24
TurfWeather Weather Station
FIGURE 2-1. Ten Times the Height Rule. If the height of the tree, T, is
8 feet and the height of the shed, H, is 7 ft then the weather station
should be placed at least 80 ft away from the tree (i.e., 10T = 10x8 =80
ft) and 70 ft away from the shed (i.e., 10H = 10x7 = 70 ft).
Another option when obstructions exist is to raise the weather station height
above the obstruction by using mast extensions.
NOTE
a. If your weather station will be inside a fence to discourage
vandalism, the fence top must be lower than the wind sensors
even if the fence is chain-link.
b. Accurate wind measurements require your weather station to
be located at the highest point in a particular region.
c. The tripod/mast height cannot exceed 10 feet (312 cm).
2.3 Communications Considerations
2.3.1 Direct Communications
Short-haul modems enable communication between the weather station and
computer over two twisted pairs of wires. This communication requires the
DCE/DTE switch on the modem to be in the DTE position at the weather
station, and in the DCE position at the computer.
2.3.1.1 Cable Lengths
The maximum distance between modems is determined by baud rate and wire
gage. At 9600 baud, the approximate range is 2 miles using 24 AWG wire.
17
Page 25
TurfWeather Weather Station
2.3.1.2 Grounding Issues
Outdoor cables may be subject to induced currents due to lightning or other
environmental factors. Therefore proper grounding is imperative to avoid
damage to the weather station and/or the Host computer.
CAUTION
To minimize the possibility of equipment damage or
personal hazard, we strongly recommend a qualified
electrician design and install the grounding and data
isolation components of a directly wired installation.
2.3.2 Wireless Communications
2.3.2.1 Transmission Ranges
Site your TurfWeather weather station within the spread spectrum radio
transmission range. Typical transmission ranges are listed below:
xUp to ½ mile (0.8 km)for the weather station 916MHz and weather station
922MHz
x Up to ¼ mile (0.4 km)for the weather station 2.40GHz
x Up to 7 miles if an optional higher gain antenna is installed on both the
weather station and the RF401 Base Station
NOTE
a. The transmission ranges assume standard weather station
antennas are used at the computer site. User-supplied, higher
gain antennas at the base station or on the weather station can
increase the transmission range.
2.3.2.2 Line-of-Sight
b. The ranges assume no obstructions are in the line-of-sight.
Line-of-sight is defined and described below.
Line-of-sight is defined as a straight path between a transmitting and receiving
antenna that is unobstructed by intermediate topography or obstructions (see
Figure 2-2). A clear line-of-sight is required to achieve the optimum
transmission range. The affect of obstructions on the transmission range can
vary. Therefore if obstructions lie within the line-of-sight, you should test your
radio transmissions before permanently installing your weather station (see
Testing Radio Transmissions (Section 2.3.2.3).

2.3.2.3 Testing Radio Transmissions
To test the radio transmission of your weather station, carry the weather station
to the site attached to the tripod or mounting pole then attempt to communicate
with the weather station using the host computer. See the TurfWeather Quick
Start Guide section for instructions. Only turn key switch on during testing
when charging cable is not connected to avoid battery damage.
If obstructions in the line of sight are preventing the weather station from
communicating, try the following:
x Relocate your weather station away from obstructions.
x Remove the obstructions.
x Mount the computer base station antenna outside of the building by
running the antenna cable through a window or cable run.
wireless communications.
Computer Site
NOTE
x Use a higher gain antenna (optional) at the computer site.
x Install a higher gain antenna (optional) on the roof of the computer site’s
building and align it above the obstructions.
If you are still experiencing problems communicating, you can
contact your distributor. To allow us to effectively help you,
please be prepared to describe, in detail, your installation and site
conditions.

TurfWeather Weather Station
APPLICATION NOTES
Wireless TurfWeather weather station systems utilize industrial
grade spread spectrum radios. Update rates for wireless systems
should not be set below 10 seconds for extended periods due to
power budget limitations. Externally powered systems that do
not use solar panels for battery recharge have no update
limitations.
TurfWeather weather station wireless systems located above 40
degrees North/South Latitude should set the update interval for
60 seconds, or greater, during periods of limited solar incidence.
Monitor battery voltage to determine power drain in your
application, and do not allow the battery voltage to drop below
12 volts. Adjust the update interval as needed to prevent battery
discharge and communication failure.
2.4 Installation Procedures
Many installation configurations for the weather station are possible. This
document describes standard installation configurations. For questions about
installation configurations not described in this document, contact your local
distributor.
2.4.1 Tripod Installation Procedures

2.4.1.2 Procedure 1b: Ground Installations
5. Once the mast height has been set, tighten all six collar bolts.
6. Install the tripod at the site. Refer to “Procedure 1b: Ground
Installations”.
1. If needed, prepare the site. A temporary site may require brush or tall
weeds to be removed and footings dug if the site is not level. A
permanent site may require pouring a concrete pad or fabricating some
other form of a permanent base.
2. Use a rubber band to attach a level device, such as the one in the 16770
Tripod Installation Kit, to the midpoint of the tripod mast.
3. Place the tripod on the site.
4. Adjust tripod footings until the mast is level. Some adjustment is
available by loosening/tightening the upper and lower collar bolts. If
more adjustment is required, then for temporary sites, remove or replace
soil under the feet. For permanent installations, use shims to adjust the
foot foundation height.
NOTE
For temporary sites, ensure the soil under the tripod feet is well
compacted. Otherwise the tripod may not remain level after the
tripod feet have been secured to the ground.
5. Secure the tripod feet to the ground (Figure 2-6).
FIGURE 2-6. For temporary sites, drive the stakes of the 16773 Tripod
Stake Kit (left) through the center hole in each tripod foot (right). The
stakes should be driven in until they barely contact the foot surface. For
permanent sites, install user-supplied bolts through the holes in each
tripod foot.
6. Follow Procedure 3: Mounting the weather station on a Tripod or Pole
(Section 2.4.1.4).
1. Cut the guy-wire cable into three equal length pieces.
2. Loop one end of each guy-wire through a Bracket eye-bolt and clamp the
guy-wire using one of the Clamps provided.
3. Install the Bracket on the tripod mast about six inches (15 cm) from the
top of the mast then loosely tighten the bracket bolts that lock it to the
mast.
4. Insert the mast into the Tripod and rotate the mast assembly until the
bracket eye-bolts all line-up with a tripod leg then loosely tighten the mast
collar bolts on the tripod.
5. Tighten the guy-wire Bracket bolts until they deform the mast by
dimpling the surface to assure the Bracket does not slide when the
turnbuckles are tightened.
6. Unscrew the turnbuckle until approximately 80% of both eye bolt threads
extend beyond the turnbuckle body.
7. Hook an S-hook to an eyelet on each of the tripod feet. Alternatively, the
S-hooks can be connected to user-supplied eye-bolts set into a concrete
pad or another fixed structure.
8. One at a time, grasp a guy-wire and loop it around its corresponding Shook to roughly determine its correct length then cut the guy-wires to
eliminate any excess length.
9. Hook the unattached end of each S-hook to an eyebolt on the end of a
turnbuckle.
10. Loop the free end of each guy-wire through its respective turnbuckle eyebolt and pull it tightly then clamp the guy-wire using one of the Clamps
provided.

NOTE
a. The guy-wires need to remain loose until after the weather
station assembly has been properly oriented. The turn-buckles
are tightened in step 5 of Procedure 3: Mounting the weather
station on a Tripod or Pole (Section 2.4.1.4).
b. Guy-wires will stretch for a few weeks after installation. You
should periodically check them for tension and re-tighten the
turnbuckles as required until they stop stretching.
2.4.1.4 Procedure 3: Mounting the TurfWeather Station on a Tripod or Pole
NOTE
This procedure assumes the weather station has been setup and
tested at the computer location (see Quick Start Guide), and that
a tripod or pole has been installed at the site.

41
Page 49
TurfWeather Weather Station
1. Location Preparation:
a. Determine the best location for the antenna, assuming that the
distance from the antenna to the RF401 base station is equal to, or less
than, the length of the NTN-Lxx antenna cable.
b. Assure that the ground rod is installed into the soil as close to the
location of the Polyphaser as is possible. NOTE: A ground wire (00
gage) is supplied but it may not be long enough for all installations. If
a longer ground cable is required, purchase a continuous length to
meet the site requirement but always use the minimum length
necessary. Do not reduce the gage of this wire if a longer length is
required. An alternate method of earth grounding may be employed
but should be confirmed by a qualified RF technician before use.
c. Mount the Polyphaser within 5 feet of the location of the RF401 base
station on a ground plane, or ground buss bar, inside a weatherproof
enclosure or building. Mounting recommendations are supplied with
the Polyphaser. NOTE: The ground plane or buss bar will also be the
connection point for the earth ground cable to the exterior ground rod,
or interior earth ground connection.
d. Connect the heavy gage (00 gage) ground wire to the ground plane or
buss bar using a 00 bolted ring or spade lug connector (not supplied).
Connect the other end of the heavy gage ground wire to the ground
rod using the brass rod clamp supplied, or connect to the alternate
interior earth ground point.
e. Verify connection to the earth ground from the case of the Polyphaser.
2. Component Installation:
a. Mount the antenna in the proper orientation, with the connector at the
bottom.
b. Connect one end of the antenna cable to the antenna and install the
cable up to the location of the Polyphaser. Assure that a drip loop is
maintained in the cable at the base of the antenna, and at the point
where the cable will enter a weatherproof enclosure or building. The
drip loops will minimize the amount of rainwater that will run down
the cable to the enclosure or building. NOTE: The minimum bend
radius of the antenna cable is 6 inches. Tight bends in the antenna
cable, or clamps that crush the cable, will damage the internal
insulation and compromise the cable. Handle the antenna cable with
care.
c. Connect the antenna cable to the Polyphaser module connector
marked ANTENNA.
42
d. Connect one end of the short COAX RPSMA Polyphaser-to-RF401
cable to the EQUIPMENT side of the Polyphaser module, and the
other end to the antenna connector on the RF401.

TurfWeather Weather Station
3. Principle of Operation:
a. A Yagi high gain antenna is a directional RF device designed to
minimize signal attenuation at the base station location, thereby
providing the maximum available energy at the antenna for
communication with the remotely located equipment (i.e.: the weather
station). This antenna does need to be aimed and the best result is
obtained with a clear line of sight to the remote transceiver. If you can
see the weather station, the system has a clear line of sight.
b. The Polyphaser senses the presence of a high voltage electrostatic
energy pulse and passes it to earth ground before it can damage the
RF401.
4. System Test:
a. Initiate the system software and verify that the RF401 will
communicate with the weather station. See “TurfWeather Quick Start
Guide”
NOTE
IMPROPER GROUNDING OF THE SYSTEM WILL
COMPROMISE ALL PROTECTIVE COMPONENTS AND
RESULT IN SYSTEM DAMAGE IN THE EVENT OF AN
ELECTROSTATIC DISCHARGE EVENT. THE GROUND
SYSTEM SHOULD BE REVALIDATED ON AN ANNUAL
BASIS TO ASSURE THAT CORROSION AT CONNECTORS
HAS NOT COMPROMISED THE GROUND SYSTEM.

A.3.6 16775—Tripod Grounding Kit
The 16775 provides hardware needed to properly ground the weather station
and tripod. Properly grounding the station prevents electrical surges and
lightning from damaging the weather station (see Section 2.4.1.6 ‘Procedure 5:
16775 Ground Kit Installation’).
The 16775 includes:
x36” (91.4 cm) long copper sheathed steel electrical ground rod
CAUTION
x Electrical couplings for connection to the ground rod and tripod
x 5 ft length of plastic-coated, #4 stranded copper cable
x 3 ft length of 14 AWG stranded copper wire with a connection lug on one
end
a. Because proper grounding of the system is required for
both personal safety and reliable system function, we
recommend a qualified electrician install the grounding kit.
b. If the station is not properly grounded, a computer
connected to the weather station can also be damaged by
electrical surges.
c. This kit is for ground installations only. A qualified
electrician should design and install and the grounding
system for a roof mounted station.
