Hi Again
I was looking at COM antennas on the ACS site and saw this antenna:

Does anyone have any experience with the Advanced Aircraft Electronices High Gain Antenna Systems antenna? It would seem that mounting on the aft canopy would be a great location if it works as advertised.
Inquiring minds need to know

They should work just fine as they look to be just a basic dipole antennas that you can make for $5 or so in parts.
The term “high gain” in interesting as by definition these are omni antennas (radiate in all directions) - as such they have no gain over a standard reference dipole. For an antenna to have gain it must radiate in one or more directions better than others. This is not a good characteristic for aircraft antennas.
For mounting keep in mind that by convention communication antennas are vertically polarized and navigation antenna are horizontally polarized. Glassing in a dipole antenna in the top of the canopy would work well for a VOR antenna. For this application I recommend you run the legs parallel to the wings to avoid nulls off the nose and tail. Better yet would be to mount it in a ‘V’ shape were the angle is greater than 90 degrees. This will help to eliminate all nulls. For a communication antenna you will need to mount the dipole as vertical as possible to be most effective. I’ve seen these type of antennas mounted in the horizontal stabilizer on Lancairs and the reports are they work well for communications.
