Coax query. RG8U, bulkhead connectors, and everything!a
I know I’m new to the room, but I need some heads. I was working HF all over the spectrum. SWR was beautiful. (1.2-2.2 swr) on any band. Suddenly SWR went crazy. I unearthed all the cable for inspection and found no cuts or breakage. I used a multimeter and found an open line on the entire length of line, so no migrating or co-mingling between the shield and center. I cleaned out all connections to ensure no degrade connections do to oxidation. I checked the grounding wire between the shield and the grounding rods, using the multimeter between the shield and rod, we have continuity. My grounding point for the radio is attached with a length that shouldn’t have any harmonic RF interaction. I can’t find the Antenna analyze yet as I haven’t used it in quite sometime. Anyway, other than the AA, is there something else that I may be missing?
