Been running with a typical 8-legged spider antenna and about 14ft of RG6 from the antenna mount to the FlightAware Pro Stick Plus. So far, so good, getting 200+NM at times so that’s great.
Decided to make an enclosure for the FlightAware and Raspberry Pi ZeroW and move the receiver to just at the antenna mount. Doing so reduced distance to less than 100NM. Leaving everything in place, and just re-inserting the 14ft of cable and I’m back out to 200+NM again.
Shouldn’t signal reception/quality/etc be better with a shorter cable? Or is there some sort of minimum length needed on a spider antenna? Or will taking out 14ft of cable require significantly different gain settings for the same antenna?
