1-4 Assembly & Installation
H-223
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.
