Send clowns,
Very simple dear boy, locate the antennas far from interference and shield the interconnecting wiring.
Take for example my private twin engine aeroplane. It is equipped with King Gold Crown nav, comm, adf, dme and gps receivers, and in this case, the very same nav, comm, adf, dme (exclude gps, not then available) units that were fitted to UAL 737's (30+) years ago.
These radios are fitted according to STC and field approval specifications and...
having all seven passengers dial on their mobile phones at the SAME time, resulted in...
NO interference to nav, comms, adf, dme, OR GPS reception.
"Tis called "proper shielding", plain and simple.
If I can do so on my rather limited budget the question remains...
WHY cannot airliners be so equipped?
PS: TOTAL cost for shielding in my installation was...$800.
Answers on a prepaid postcard, please...
