Antenna feed line length question
Posted: Wed Jan 10, 2018 8:20 pm
Hi All,
I'm new to the world of SDRplay (just ordered the RSP2). My questions mostly relate to the distance of the feed line I can potentially use between the SDRplay and my external antenna.
The only listening post available to me is not ideal - a room inside a concrete structure, approximately 5 meters from the nearest door/window and the eventual external antenna. Is this distance going to be too excessive? I mainly plan to listen to signals below 20MHz to begin with (MW & SW), but eventually would like to have an antenna for VHF as well (primarily to receive aviation broadcasts).
Would I be better off trying to place to RSP2 closer to the external antenna and getting a longer USB cable or would that be a drawback? I've successfully used USB devices up to a distance of 3 meters in the past, but not sure if that sort of distance would be too detrimental for the RSP2.
Thanks, Greg
