I'm not familiar with using long-wire antennas or baluns for them, but I've read some good things about using long-wire antennas.
My limited understanding of long-wires is that you can use virtually any length of wire and it can be made resonant at many different frequencies. Some hams and SWL'ers like using those for working 160 meters or lower frequencies because they don't have to string up hundreds of feet of wire just to match a limited frequency range within one band.
One thing bad about them I've read is that you can't bring that wire anywhere near your radio because it will radiate along it's entire length and you could get a nasty burn. That's where the balun and a coax feeder come in.

If you have an Apple iPhone. There is a called "My First Antenna". It calculates leg length and total length of the Dipole antenna. Works for 10m SSB, 20m PSK, 20m SSB, 40m PSK, 40m SSB, 80m PSK, 80m SSB. Another program called "HamAntCal v3.1" also calculates wire lengths. On VHF 30 to 300 Mhz. and UHF 300 to 500Mhz. Another program "Antenna Tool" go antenna type drop down menu. Punch in your antenna type and it automatically calculates length.

Thanks for that. I'll check those out!
Wanted to buy ready-made antennas first, then work on constructing my own. I may put up a broad loop around the property since I have the room and the trees to do it. But it may need to wait until my next cash infusion. I'd sort of forgotten how expensive this hobby can be. Literally, the sky's the limit :)
