On my CH 750 I installed the ELT ant. on the top near the baggage rear bulkhead. I installed the com and the Transponder ant on the bottom. The Com ant is stiff wire and has a 45 degree bend in it so is not very close to the ground, and located just forward of the seats, the transponder is very short and located just aft of the bottom access hatch. All of the GPS are on top of the panel. All has worked well for 5 years.Hope this helps, I have pictures on my home page, not very good on showing the ant on the bottom, unless you have good eyes.
