Don't forget that 3/2 waves in phase doublets, give you gain and a multilobe advantage for covering more of the country on Field Day. Now I am not talking the G5RV, but the W5GI with true in phase action along each side.
He also has the Vee beam without a in span phasing line, the D3 Plus. Both are on his web page, www.W5GI.com. These can be fed with ladder line or 1/4 wave coax stub for one band use. The 5/8 wave legs of my IDEZ design, (Inverted Double Extended Zepp) gives you multi lobes and gain, but you have to have a lot of space, and one support pole. Just make the antenna of your favorite conduit wire 14 ga insulated, in any color. Each leg is 5/8 wave at lowest band, (160 or 80m). Feed the center with 450 ohm ladder or 300 ohm line, and go to an external current balun, then to coax output of your tuner with a one foot jumper or double male coax plug. Finally, for Field Day, a low Horizontal loop is easy up, if the legs are individual wires joined at 3 corners with wire nuts. Make this loop 2 waves on 40m, and it will have respectable gain like a beam on higher bands, and 3 dB on 40. It can be tuned to 80m as well. It only has to be up 20 feet to have both high and low angle performance. If oriented to have one side to most of ham population center, you will cover the country well. Feed it in the corner opposite the direction of most ham population, as the lobe pattern favors the side opposite feed. Again, 450 ohm ladder, or 300 ohm line feeder any length. (we had 150 feet last year). Same deal, external balun, on Tee tuner coax output. 4:1 Van Gorden baluns are efficient and work well.
