Introduction

The 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 1/2-turn cam-lock
mechanism.

Key Features:

• 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

Assembly

The 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:

Quantity Description

1 Adjustable mount, complete with 2 set screws, 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 elemebts 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)

Install the Director and Reflector Elements

Element Cam-Lock

3

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 reflectpr pair.

Step 1: Insert Cam Element Step 2:Insert Notched Element Step 3: Rotate Cam Element 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.

Step 4: Install The Four Dipole Elements

Introduction

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.

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.
