Good morning listers…
Can anyone suggest/recommend is there a “best” placement for the transponder antenna? I am building a CH650 and was planning on putting it on the center line in the general area of the brake pedals.
Also, is there a way (short of speaking to tower) that I can verify the altitude my transponder is broadcasting?
Any help or advice is certainly appreciated…

Hi Steve,
I put my transponder and comm antennas behind the seats on the fuselage bottom. I think it will get crowded if you put the antennas and associated mounts and cables in with the rudder pedals.
You are required to have your transponder certified by an avionics shop before turning it on in the NAS. This verifies all the signals are clean and accurate. You can get a VFR or IFR certification. It must be repeated at regular intervals (2 years?).

Hi Steve,
I placed my transponder on belly center behind the seats. Ease of access and all.

I put mine under the left seat with the cable routed along one side of the rudder cable tunnel. I can reach the antenna connection from the spar bolt access panel. The general recommendation is to put it on the belly at least three feet from any other antennas.
The Transponder/ altitude encoder is required to be certified every two years.

Steve:
The simple wire antenna works well. All it requires is Facing to earth, and a ground-plane. The more expensive blade type does no better. And they are not any lower drag - mater of fact they are higher drag for our planes.
Your placement is OK, I would prefer something a bit further away from the brake cylinders so you do not have to deal with the antenna connection while working on the brakes AND so brake fluid does not work its way to the COAX and connector.
Unless you bring the plane to an avionics shop the only way to get conformation on your xponder & Alt encoder is to talk to ATC.
