My transponder antenna is mounted on the bottom of the fuselage directly behind the seat and bolted through a 16 inch square sheet of thin aluminum glued to the floor of the fuselage. I have an Icom A-20 comm/nav and a Narco ATI50 transponder. Everything seems to work just fine.

Good evening, again, I've been going through the archives and found some lite information about antennas. Are you guys mounting the antennas inside of the aircraft? I have a comm/nav antenna, and a transponder antenna. What have you guys found was a good place to mount them? Thanks! Trevor

Hi netters, I was curious if anyone is using Wicks Aircraft Supply this product or similar? And if they are where are they mounting it getting areal good signal? David Swanson bdazzca...@aol.com

Ok that didnt come out right.. The part number is VHF5T. Its the composite antenna trying to figure out where I can mount it without it interfering with my controls. David Swanson bdazzca...@aol.com

HI Netters, Im still kind of new at all this yet How many antennas are there in an airplane usually? I know nav/com. What what else? Where do the antennas mount? David Swanson bdazzca...@aol.com

David,
The bare minimum is one antenna for the VHF radio.
Then, depending on what you intend to do with your craft, you might want:
radio-navigation:
- GPS antenna
- Transponder antenna
- VOR antenna
- ADF antenna
emergency:
- Emergency Locator Transmitter antenna.
- VHF antennas: usually on top, but you can sink one in the tail fin
fiberglass too.
- GPS: necessarily on top
- Transponder: bottom
- ADF: bottom
- VOR: bottom (top possible)
- ELT: recommended position is on top, near the tail fin (to preserve it
in case of crash)

If you are a two place craft in the US, include the ELT in "bare minimum". The GPS that I have, uses a little receiver module that is also the antenna, and I have it placed on the back shelf. Many are placed on the windscreen shelf, so they are not an issue. I have a COM, which is mounted on top of the plane because I made my seats out of carbon fiber, which took away the option of mounting it behind the seat, which I did in my first KR. My ELT is mounted behind the seat, but that may not be the best place for it, hope I never find out. You can see it at: http://krbuilder.org/Electrical/index.html PS: There is a search option on my site. I just remembered because I could not find my ELT installation, so had to search for it. The search menu pick is at the bottom of the dropdown menu on the home page. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2007 - KR Gathering There is a time for building and a time for FLYING and the time for Flying has begun. Daniel R. Heath - Lexington, SC ---Original Message--- The bare minimum is one antenna for the VHF radio. Then, depending on what you intend to do with your craft, you might want: radio-navigation: - GPS antenna - Transponder antenna - VOR antenna - ADF antenna emergency: - Emergency Locator Transmitter antenna.

Tim, I have two points. First, the ELT will transmit on 121.5 Mhz, right in the middle of your comm frequencies. When the antennas are in close proximity, it will send an extremely high level of power into the receiver. That might fry it. The solution is to keep the ELT and comm antennas as far apart as is possible. Secondly, 90% of the signal is transmitted in the part of the antenna nearest the feedpoint. The top half of the antenna is there to make it resonant, but radiates only about 10% of the signal. If you in effect have the majority of the antenna shielded, then your signal will bounce around the inside of the plane like inside a microwave oven. Have you thought about imbedding the antennas into the canopy? It might not be vertical polarization, but at least it would radiate outside the plane. Just a thought.

Thanks Jim, I believe you are correct in all of your assumptions. and have confirmed with "Poly fiber" that it will indeed interfere with radio transmissions.
