Hi Mark. Well, my ops will be HF and both in motion and stationary. My major unknown is if the RV isn't an Airstream (it won't be) what are the possibilities of mounting the antenna (not on the rook). I've used a Tarheel on the rear ladder with good results but that was then, this is now. The RV isn't picked out yet either. I am just wondering, ahead of time, what results vs. placements others have had success (or not) with. I don't expect more than reasonable results...no contests from the RV. We're getting closer now I think. Thanks, B
