I have a Sony ICF7600GR world band radio and was wondering what
portable antenna I could use that has good reception on all of HF and uses the 1/8 External Jack plug on the receiver, but isn't like $50+. I have been playing with a homemade dipole antenna with a mono 1/8 plug and two wires going in either direction, but even though I know people put shortwave antennas up in trees, I learned one good thing, and that is make sure the tree(s) that you use, are defiantly trees you can easily climb, if your wire gets stuck up in the tree, LoL. I had that issue the first time I used my dipole, with the one tree, not wanting to give the antenna wire back. |

Unless something is an active antenna, or a tuned loop, basically any expense is going to go for cosmetics. Because you can't really come up with anything that isn't just a piece of wire. So you'll pay for some neat little gadget that lets you wind up the wire. But it won't work any better than some wire. Most people do get by with a "random length of wire" (which mostly ends up being a relatively short piece of wire for most of the frequencies in the shortwave range). In the old days, they'd actually string it up out the back window and to the tree in the backyard, something that may not be available to many nowadays, living in apartments and such. So you just let the long piece of wire hang out the window, or lie on the floor. To the tree has the advantage that it's outside and away from the house, but there isn't anything really better about the antenna compared with a similar length of wire lying on the floor. Keep in mind that many portable receivers are intended for use with the built in whip, and if you start adding too long a length of wire it will start overloading (because they put in lots of amplification to make up for the lack of antenna length on the whip). Few will bother with actual dipoles, since they are frequency selective and they will start getting long the lower in frequency you go. Michael |
