Thanks, that is useful data! From what I could gather from different sources on the internet, typical VOR ground equipment operates with around 100-200 W ERP, am I correct? > Antenna cable losses have to be added for in airplane performance (and > they are usually significant). I will make the antenna gain configurable for each station/aircraft, so any cable losses can be added into the system that way. I think that losses might not be very high in the VHF airband unless the aircraft uses very crappy coax or a significant length, but that might change for GS frequencies in the 300 MHz range, of course.
