Hi All, I would echo Joe's comments. I use pretty much the same setup as he does. I only have the one PAR EFHW (the 10/20/40 model), and it works very well. For example, at Ozarkcon last year, I used it from my motel window to a parking lot light pole, and had excellent results using my ATS-3.
I feed my 88 ft. dipole with 300 ohm feedline (the good stuff--from the Wireman) instead of 450 ohm line, which I find to be a bit too bulky. It works fine, and on all bands from 80 through 10. WARC bands can be a bit sticky, but my MFJ tuners all seem to handle it, including the smaller portable model. Sometimes adding a few feet more to the feedline helps on those bands. An "all band" system doesn't get much simpler. When the availability of antenna supports is a problem, I usually opt for my MP-1 system. This system works a lot better than most people realize, particularly if you add a section or two under the coil, and spread more radials. It's still very portable, and very easy to set up. Sometimes, a vertical is your best option. If you want to try something a bit more exotic for portable use, I would strongly suggest you check out the new 3 element portable beam from SuperAntennas. We set that up recently at the Quartzsite, Arizona hamfest, and had a blast with it. I wasn't able to break the pile-up trying to work the VP8 group down in the Falklands, but did work just about everything else I could hear, and QRP at that. I think this is going to be a great Field Day antenna.
