Hi,
I bought a used Comant CI-122 antenna intended to connect to a second radio (8.33 requirements in Europe).
Although this antenna is made for an "under-the-belly" installation, I want to use it on top of the fuselage (is this at all possible ??)
Before installing, I hooked up the antenna to a coax (to simulate aircraft installation) and a handheld radio. Called the tower from 1.5NM away and they did not read me. Changing to the small whip antenna on the handheld cured the problem, "reading you five"...
Measured the coax and there is nothing wrong with it, I even hooked up the coax to an existing antenna installed in my house (for VHF RX/TX) through a double BNC-connector and readability was "five" again.... This leads me to believe that the Comant CI-122 is U/S.
How can I make sure the CI-122 is working properly ?
Your tips and tricks are most welcome !
