"Dave" wrote in message ... if it is insulated wire it must be cut, if its not then it doesn't. though you will see some effect of folding it back even with insulated wire it won't be the same as cutting the wire shorter. No one said it would be resonant on the SAME frequency, just that there will be some effect. I have heard about an antenna design for a shortened dipole using 3-conductor home electrical wire. At one end, the green is connected to the cobra-head and the black and white wires are soldered together. At the other end, the black is soldered to the green. Viola -- a linear loaded dipole! I haven't tried it, but if it works, you may very well get your desired frequency with folded wire. I would strongly suspect it will be a compromise antenna as opposed to one with a gain, though. -- 73 for now Buck N4PGW |
