| Transmission lossI am not a Heli flyer yet. But maybe I can help a bit in this arguement. If you have receiving material and put it near a conducting body then you will start to get interference from the conducting body. Earlier someone said that Carbon fibre is conducting, which will mean that it will interfere with the signals. If you are unlucky you will create what is called a Gausian cage, which will completely block the signal.
However, I think that today, receivers are sensitive enough to be able to pick up even very low signals, so maybe 10 years ago, any interference was to be avoided but nowadays it doesn't really matter.
I don't know whether you have multi-storey car parks where you are, but where I am we do.
They are mostly concrete construction with lots of holes for windows, but iron wire cores to make sure that the concrete does not stretch (which we all know concrete is very bad at dealing with). Concrete is not a conductor, so driving into a just a concrete room listening to the radio would not be a problem. BUT because of the irons cores, the RF signal is affected by the gausian cage effects and the radio cannot receive the signal within the multi-storey car parks.
