I replaced my KT76A with a GTX327 and it seems to work most of the time. In the past 20hrs of flying, 4 times I've had ATC tell me they can't see me. Once, recycling the transponder fixed the problem. One of the four times, they said they can't see my altitude. The other times, they can't see me at all (position or altitude). The interesting thing is that my ADSB can always see me, even when ATC can't. This leads me to think it's an antenna problem.
I was told that it's because of my post-style antenna. Like this one: https://www.aircraftspruce.com/catalog/avpages/av22.php?clickkey=4083
I was told that the GTX 327 needs a CI-105 type of antenna. So my question is, will this one be ok? https://www.aircraftspruce.com/catalog/avpages/antenna11-13830.php?clickkey=4083
If someone can educate me about the different types of antennas and what's the difference between CI-101 vs. CI-105 and why there's such a big price difference within each category. For example, this one made by Comant is almost 3x as much as the Red Tail one. https://www.aircraftspruce.com/catalog/avpages/comant105.php?clickkey=4083
Which one should I get? Also, why did the post-style CI 101 work just fine with my KT76A, but not the Garmin GTX 327? I've never had a single problem with the KT76A.
Thanks.
