Repeater BuilderThis is a side mounted installation on a tower, Rohn 25. The
first G7-220 antenna was damaged in the wind. The current one seems to get
noisy at times and we suspect the antenna as the culprit. When we installed
this one we also used a standoff to help stabilize the top of the antenna in
the hopes that it wouldn't be bothered by storm winds. As soon as we get some
time to take a closer look at the problem we will investigate the issues a
little more to be sure the real problem is the antenna.
Thanks for the input.

Tim,
What type of location are you using? Is this antenna going on the side
or top of a tower.
You can get a DB224 EE for 220. That would be my first choice. Antenex (
now LAIRD )
has a 3 DB omni fiberglass antenna as does COMTELCO .

FG2203
220 - 225 MHz
222.5 MHz
107"

Have a look at these antennas I have used the Antenex and Comtelco antenna
lines
for my own use as well as other groups repeaters.

What's wrong with the G7-220? They generally do quite well. I using the
Comet CX-333 at a couple of sites & have had no problems with it. One site
has a 2 meter & 440 repeater & 220 link all triplexed on the same
antenna. Wish it had a little more gain, but probably only so much you can
do when trying to get a good gain/pattern on 3 widely spaced bands.
