I'm installing a Stratus ESG to replace my KT=76A transponder and get ADS-B out. I already have my GPS antenna for the Garmin 300 XL under my cowling and don't have the room to give the required 1' distance between the two antennas. I was thinking of installing the second GPS antenna in the wingtip. Can I run the cable in the tube with the strobe/nav light wiring or would this affect the signal? I don't know how sensitive the GPS antenna is and am looking for advice.
