1.0 Introduction
The W
ATER
LOG® H-223 is a rugged, high-gain Yagi antenna designed for use with fixed location GOES
Satellite Data Collection Platforms. The antenna has two 5-element Yagi antennae mounted on an
extruded aluminum boom. The one-piece reflector and director elements lock firmly into place with a
unique ½-turn cam-lock mechanism.
Key features include:
Rugged, heavy duty construction
High gain
Circular polarization
Fully adjustable mount fits on a 2-inch pipe mast
Can be disassembled for easy transport and shipping
2.0 Assembly
The W
ATER
LOG® H-223 antenna is shipped disassembled in a 4" x 4" x 48" box. You will need a 6-inch
adjustable wrench and a pair of pliers to assemble the antenna. Unpack and familiarize yourself with the
parts. You should have:
Quan Description
1 Adjustable mount, complete with 2 setscrews, 2- bolts, 2-nuts and 4-washers
1 1" square x 38" boom
4 Dipole elements (7" long, with threaded stud)
1 Reflector-A element (14-3/4" long, with eccentric cam)
1 Reflector-B element (14-3/4" long, with round notch)
3 Director-A elements (13-1/4" long, with eccentric cam)
3 Director-B elements (13-1/4" long, with round notch)
Refer to the assembly drawing for the proper location of each element. Install the elements as follows:
Install three sets of director elements (13-1/4" long)
Install one set of reflector elements (14-3/4" long)
Install four dipole elements (7" long with threaded stud)

Assembly & Installation Instructions 1-1
2.1 Install the Director and Reflector Elements
Element Cam-Lock
The Yagi elements are installed in pairs using a cam-lock mechanism to rigidly lock each element in
place. Each pair consists of one element with an eccentric cam and the second with a small round notch
in the center. Follow Steps 1 thru 3 to install the three 13-1/4" long director pairs and the 14-3/4" long
reflector pair.
Step 1
Insert Cam Element
Step 2
Insert Notched Element
Rotate Cam Element
Step 3
into locked position
Step 1: Insert the element with the cam into the boom until the cam
is in the center of the boom. Rotate the cam until the side passage is unobstructed. Do not attempt to
insert the notched element first, the 2nd element will not slide past the notch.
Step 2: While holding the first element in place, insert the second element (with the round notch) into the
boom and rotate it until the notch is aligned with the cam. Slide the notched element into the boom until
the notch is approximately centered inside the boom. By hand, rotate the cam element until the cam rubs
against the notched element. Slide the notched element back and forth until you feel the cam drop into
the notch. Continue to rotate the cam element by hand until it turns approximately 30 degrees. If it
won’t turn 30 degrees it is not properly aligned with the notch in the other element.

Step 3: With an adjustable wrench, continue to rotate the cam element past the 30 degree point until the
wrench flats are parallel with the boom. At this point the two elements will be firmly locked into place.
When installing the two reflector elements, you will need to work the elements past the coax leadwire
inside the boom. The leadwire is routed in one corner of the boom. Insert the reflector elements first thru
the hole in the boom opposite of the leadwire. This will provide leverage while working the element past
the leadwire into the opposite hole. After installing the director and reflector element pairs, make certain
the wrench flats of all 4 cam elements are parallel to the boom.
Step 4: Install the four dipole elements. The dipole elements are 7" long and have a threaded stud on one
end. Screw the threaded studs into the boom and tighten lightly with a pair of pliers. Do not over
tighten. Over tightening may strip out the threads in the plastic insulator inside the boom.
Install the four Dipole Elements

Assembly & Installation Instructions 1-3
3.0 Installation
The adjustable mount is designed to fit over a standard 2-inch pipe mast. It works in both the vertical
and horizontal positions. The antenna must have a clear, unobstructed view of the satellite. Mount the
antenna above the reach of vandals and away from pipes, wires and other metal obstructions. The
antenna should be mounted at least 6 feet (2 wavelengths) above the earth to provide proper impedance
matching. Install the antenna with the side marked “this side up” appropriately.
Rotate the adjustable mount to the desired azimuth position. Tighten the two setscrews against the pipe
mast, then tighten the two jam-nuts to prevent the setscrews from working loose. Raise the boom to the
desired elevation, then tighten the two 1/4" hex bolts on the mount. Strap the coax cable to the pipe mast
as needed to prevent wind damage.
4.0 Lead Wire
Keep the lead wire as short as possible. Use RG-58 (or preferably LMR-240) 50 ohm coax cable. For a
lead wire longer than 20 feet use LMR-400 or similar low loss cable. Install a lightning arrester or other
protective device in the gauge station. Use a drip-loop or roof jack to prevent water from following the
coax into the gauge station.
