Hi can any one out there please advice me as to a good home made aerial system from wire that will cover most if not all of the HF bands .
I have looked at a long wire & both dipoles & dublets but cant decide which one to go with .
If any one can throw some sugestions this way I would be gratefull .

I'm planning to build a fan dipole sometime in the next few weeks. Still trying to decide how to support/configure it but they seem to be among the cheapest and easy to build multi-bands.

Put up a 130-135 foot wire, with an insulator in the middle of it, as high off the ground as you can get it.

Feed the wire at the center on each side of the center insulator with open wire line you can make yourself out of the same wire you use for the antenna itself. Use anything that insulates for feed line spreaders to keep the spacing of the feedline uniform. Feedline conductor spacing can be anything from 6 to 2 inches, your choice, not a critical dimension. Make the feedline long enough to reach from the center of the antenna to where your shack is located.

Buy/build a balanced link-coupled antenna coupler to
interface this system with your transmitter or transceiver.

Enjoy the antenna on all HF bands 80-15 meters.

I put up a 160m loop of about 524 feet of wire and feed it with 47 of ladder line and I use it on 10-160m without any problem (use a tuner of course). Very cheap and easy to put up about 35 ft. off the ground

With the wire antenna outlined above, make a 600 ohm feeder, 6 inches wide, as long as required, connect the feeder to a 4:1 balun, then connect a short section of RG58 into a good ATU and you can have a 1:1 SWR anywhere from 10 metres to 160 metres.

Mine is parallel dipoles fed by one coax line. Was made before WARC bands but my Mighty Fine Junk tuner makes up for that.
