    just to add to my last, 15M is OK and I had a fault on the plug. SWR on 15/12/10 is about 2.5:1 at resonance, but that is with the antenna sitting on the roof

      just to add to my last,

      15M is OK and I had a fault on the plug. SWR on 15/12/10 is about 2.5:1 at
      resonance, but that is with the antenna sitting on the roof for tuning,
      hopefully this will improve when hoisted up to 33foot.

      CU David, ...- -.- ..--- -.. .--. -..
