I like resonant, voltage-fed verticals for their simplicity. For field ops, they can be a very quick way to deploy a working antenna. On 40 meters, for example, you're only dealing with 70ft- or 35ft if bent like an "L", Half Square, Bobtail, etc.
If you could catch Murphy on vacation, and if you can raise a large enough balloon to support ~268ft of smaller gage wire, you can go with a voltage fed half wave using an LC tank to tune it. Tap up the coil from the ground end with your coax for a 1:1 SWR (assuming your LC is properly resonated) Your farm isn't near any airports, is it? OTOH if it's windy, this could be a rather frustrating event. (technically, you're 'pushing it' a little with anything over ~200ft in height) You don't need much of a counterpoise, feeding this way- roll out however much chicken wire or wire cloth as you care to- or think 'radials', if that is your preference. A denser, shorter radial field or counterpoise ought to work pretty well. Having the current max up 134ft couldn't hurt. It ought to play reasonably well. As always, more ground is better ground. I like the roll(s) of chicken wire approach. 73, David K3KY >The last thing I need is a reason to generate flammable gasses in bulk :) > >We homeschool, so maybe that would fit the stereotype everyone expects. >"And then they did a chemistry experiment and blew up their garage." > >I've thought about an inverted L at home, I have just short of an acre, I >think the above ground part wouldn't be a problem its the radials.
