In theory there should be no interaction at all between the two lines. The coax is not perfect but also the appall run is only 8 inches The thing to really think about is how far is the GPS antenna from the Hf transmitting antenna? The effect of having the the GPS antenna in the near field of a 500W HF transmitter is going to be orders of magnitude larger then then 8" parallel But it is not so bad the Thunderbold is designed to handle "hold over" well. So if your HF transmitter jams the GPS it will do find so long as you don't transmit for many hours and days with not break. I'd be a little worried if you were sending digital mode for 8 or 20 hours at a time. Chris Albertson run.
