3.7-Meter Earth Station Antenna
Introduction |
|
Like all Andrew earth station antennas, the 3.7-Meter Earth Station Antenna provides |
|
||
|
|
high gain and exceptional pattern characteristics. The electrical performance and excep- |
|
|
tional versatility provides the ability to configure the antenna with your choice of linearly- |
|
|
polarized 2-port or 4-port combining network. That versatility is provided at the time of |
|
|
initial purchase, as well as in the future, as your satellite communication requirements |
|
|
evolve. |
|
|
The aluminum reflector is precision formed for accuracy and strength requiring minimal |
|
|
assembly. The versatile pedestal mount can be purchased with either manual or motor- |
|
|
izable capabilities. The pedestal mount features 180 degree azimuth coverage in three |
|
|
continuous 120 degree overlapping ranges and executes 90 degree continuous eleva- |
|
|
tion adjustment. This large adjustment range provides non-critical foundation orientation |
|
|
and the ability to view geostationary satellites from horizon-to-horizon, from any location |
|
|
worldwide. |
|
|
The motorizable pedestal mount features self-aligning bearings for the elevation pivots, |
|
|
resulting in "zero" backlash. This mount can be operated manually, but has the ability to |
|
|
be upgraded for motorized operation, including steptracking/Smartrack™ applications. |
|
|
The motorizable mount type is indicated by the ES37MPK or ES37MPJK letters within |
|
|
the antenna type number. The addition of the letter "J" within the antenna type number |
|
|
indicates that the mount includes azimuth/elevation machine jackscrews, instead of cor- |
|
|
responding azimuth/elevation strut assemblies. The azimuth/elevation jackscrews are |
|
|
equipped for integration with the optional motor drive systems. |
|
|
A manual pedestal mount is also available. It provides the same strong and versatile |
|
|
combination of mechanical features as the motorizable version; except that the elevation |
|
|
and azimuth axes are locking types, instead of bearing mounted types. This mount type |
|
|
is always equipped with manual struts and a fixed mount for the separately-ordered |
|
|
combining network. This mount has been designed for manual applications only and |
|
|
cannot be upgraded to a motorizable mount. |
|
|
The aluminum enclosure and hot-dipped galvanized steel mount maintain pointing accu- |
|
|
racy and ensures durability and reliability. The antenna and standard manual mount with |
|
|
enclosure will survive 125 mph (200 km/h) wind, in any position of operation, without |
|
|
damage or permanent deformation in moderate coastal/industrial areas. Severe condi- |
|
|
tions require additional protection. |
|
|
Andrew provides a complete line of available options, including field-installed electrical |
|
|
anti-icing heaters, motor drive systems (with power interfaces addressing domestic and |
|
|
international standards), remote microprocessor antenna control for motor drive sys- |
|
|
tems, pressurization equipment, and interconnecting HELIAX® cables and waveguide. |

3. |
Never stand underneath any object while it is being lifted. |
|
|
4. |
Always wear a hard hat, especially if someone is above you. |
|
|
5. |
Make sure no person is in or under the reflector while it is being lifted or positioned; |
|
|
personal injury can result if the reflector assembly falls. |
|
|
|
6. |
Personnel should never be hoisted in or out of the reflector by the crane; personal |
|
|
injury may result. |
|
|
|
7. |
Andrew earth station antennas supplied to standard product specifications will survive |
|
|
125 mph winds in any operational position in moderate coastal/industrial areas. Severe |
|
|
|
conditions require additional protection. Should it be expected that winds will exceed |
|
|
|
125 mph, it is recommended that Andrew antennas be steered to specific azimuth and |
|
|
|
elevation orientations to minimize wind forces upon the structure and thereby increase |
|
|
|
the probability of survival. |
|
|
|
8. |
It is recommended that all cross-axis waveguide and coaxial cables are secure such |
|
|
that high winds will not cause excessive flexing. Position the antenna to an elevation of |
|
|
|
90 degrees. The azimuth jackscrew should be placed in the center of its travel. |
|
|
|
9. |
When the antenna is transmitting, severe eye injury or injury to other parts of the |
|
|
body can result from exposure to radio frequency (RF) energy. The antenna must be |
|
|
|
turned off before entering the area in front of the reflector and near the feed. |

A-325 Tensioning
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
During the installation process, there are several references to the A-325 hardware tensioning procedure. The A-325 hardware must be properly tensioned to avoid slippage between bolted surfaces under high loads. Slippage can cause the corresponding assembly to move, causing antenna misalignment. When designated, the A-325 hardware should be tightened according to the following tensioning procedure.
NOTE: Tensioned bolts are for final connections only and should not be loosened for reuse.
Lubricate the bolt threads with the provided stick wax to reduce friction.
Insert the bolt, and add a flat washer—if required. Do not allow wax under the flat washer.
Add the nut, and finger tighten.
After the connections are complete, tighten the bolts until the surfaces are joined and the nuts are snug (for example, full effort of a person using an ordinary spud wrench). Do not proceed with Steps 5 and 6, unless the connection is final and is not intended to be loosened again.
Note: If the bolts are loosened after Steps 5 and 6, discard and replace with new hardware.
Using a felt-tip marker, mark the nuts and the ends of the bolts with a straight line as shown in Figure 3-1a and Figure 3-1b.
Tighten the nuts further with an extra long wrench until the nuts are moved 1/3 turn (120 degrees) as shown in Figure 3-1a for bolt lengths less than four diameters and 1/2 turn (180 degrees) as shown in Figure 3-1b for bolt lengths over four diameters.

Installation Procedures |
Mount
Unpacking
Assembly
(Using a Crane)
The elevation/azimuth mount design simplifies installation, minimizes foundation requirements, and enables horizon-to-horizon coverage from any worldwide location. The ground mount assembly enables 180 degree positioning for selected azimuth viewing. Azimuth range coverage is plus or minus 90 degrees, divided into three 120 degree continuous ranges with a 30 degree overlap. Elevation adjustment is continuous from 0 degrees to 90 degrees.
After ensuring that the foundation has been properly prepared, the ground mount assembly process may begin.
The pedestal ground mount assembly arrives in a packaged wooden crate as shown in Figure 3-2 below. The mount can be positioned manually or by using a crane; however, Andrew recommends that this procedure be performed using a crane to ensure speed and ease of installation.
Figure 3-2: Crate Unpacking
As stated previously, the pedestal ground mount installation process can be conducted manually or by using a crane. The following steps provide the necessary procedures for installing the ground mount assembly using a crane.

Step 1
Step 2
Step 3
Step 4
Carefully remove the ground mount assembly (P/N 208800 - motorizable or P/N 202680-2 manual) from the packing crate. Leave the steel strapping intact to avoid disengagement of the panning frame from the square-tube weldment during the ground mount installation.
Securely attach the crane to the ground mount assembly using a sling, and carefully raise the entire ground mount as shown in Figure 3-3.
Figure 3-3: Raising Ground Mount Assembly
Align the ground mount assembly directly over the anchor bolts (P/N 203314 - manual or P/N 203666 - motorizable), which should have been previously mounted in the foundation pad.
NOTE: Ground mount positioning on the foundation is dependent upon predetermined azimuth viewing requirements. The ground mount assembly arm should be positioned opposite the satellite requirement. If your site is in the Northern hemisphere, your satellite will be located in the South. If your site is in the Southern hemisphere, your satellite will be located in the North.
Lower the ground mount assembly onto the anchor bolts with the corresponding hole pattern.

(Without a Crane)
Step 1
Step 2
As stated earlier, Andrew recommends the use of a crane during this installation process; however, we recognize that a crane may not always be available. If a crane is not available, the following steps provide the procedure for installing the ground mount assembly without a crane.
Carefully remove the ground mount assembly (P/N 208800-motorizable or P/N 202680- 2- manual) from the packing crate. Leave the steel strapping intact to avoid disengagement of the panning frame from the square-tube weldment during the ground mount installation.
Lay the ground mount assembly on its side, in line with the anchor bolts (P/N 203314manual or P/N 203666-motorizable) as shown in Figure 3-5.
NOTE: Ground mount positioning on the foundation is dependent upon predetermined azimuth viewing requirements. The ground mount assembly panning-frame arm should be opposite of the satellite requirement. If your site is in the Northern hemisphere, your satellite will be located in the South. If your site is in the Southern hemisphere, your satellite will be located in the North.
