You guys want a good portable antenna, try the Eagle One Vertical at www.w8afx.com Its basically a 40 meter quarter wave vertical (33 feet tall) and works great on that band without a tuner but will work other bands with a tuner. I have one up at home with an Icom AH4 tuner at the feedpoint and it works 10 thru 80 meters via the tuner. The good thing about the Eagle One is that it is telescopic and collapses down to 44 inchs when not in use ! The guy that makes them, Steve Sheers is a super nice guy to deal with and sells them by itself, with a tripod mount, or a ladder mount kit for RV's and motor homes. I think he also sells a mount that goes on a trailer hitch for stationary mobile operation. Check them ot.
