It is time for me to start installing the antennas. So, where do I place them?
For comm, I have two CI122 bent whip antennas for the rv-10. I strongly prefer the bottom for looks, but I'm ever so slightly worried about performance. On my -6a, I have two placed under the seats as far apart as possible. This works okay but may not be the best. They seem to have an issue with transmit/receive exactly forward. 2-3-degrees off forward and they are fine.
For GPS, I plan on either overhead between the doors (mounted inside the cabin) or just in front of the firewall and just below the top cowling. Under the cowling works okay in my -6a. But slightly concerned with heat. I have had a few unexplained loss of signal in the -6a, but I doubt this was due to heat as it is random. Sometimes just after startup. But this may be due to the 2-GPS and 1 XM antenna all being mounted very close to each other.
Transponder and ADS-B??? Transponder is most likely under the tunnel just in front of the spar. Easy to route the cable and still a short run of cable. How close can the ADS-B be?
VOR/GS will most likely be the Bob Archer type in the wing tips. Other option is cat whiskers on the top of the vertical stab.
So, what say everyone? Any reports of performance issue would be great.
