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.

One wants to avoid a "blind" area from the main gear as much as possible (but one is transmitting downwards and not just sideways). Personally, I'm much more interested in how an instrument is actually working than a bunch of certification details. At a not-too-busy airport, and at a "quiet" time, tower people have ALWAYS been willing to help me with telling me my transponder height. When I was having occasional serious noise on my ICOM radio transmissions and receptions (occasional is the worst kind because you don't have a constant signal to work with; it turned out to be noise put onto the power bus by the Becker transponder power supply - the cure was a good noise filter on the power input to the ICOM), again the tower people were ALWAYS willing to tell me what they were hearing. These guys have invariably been helpful.

From: FLYaDIVE Hello Sabrina: I am not sure if the TCAS would work or be accurate enough. The TCAS ignores signals that are too close and intrepids them as your own. You many have to be 0.1 of a Mile away (528 Ft) or 0.1 NM (607 Ft). The readout on the unit has a resolution of only +/-100 Ft. BUT! It would be interesting to try.
