I am planing on putting up an outdoor wire antenna, but I am a little undecided on what antenna I should make. Normally I would try experimenting with a few and choose the best, however I am running out of good weather and would like to get one up before snowfall. I am planing on using it for receive only on shortwave bands. I live out of town and have a fair amount of space to put one up. I don't have a tower yet and am planing on using trees. I have one really big tree that is taller then anything around that I can use. Most other trees are not taller then the house. At first I was going to put up a 100' long wire, but I would have to put it lower on my big tree in order to keep it horizontal to the ground. I thought however that maybe I should do an inverted V since I have one very high point but I don't know if they are better then long wire or not. I also noticed that there are multi-band long wire and multi-band inverted V. Do these really help over single wire? Building them isn't much of a problem for me since I enjoy building my own stuff. I currently have 100' of shielded 12 gauge wire, PVC conduit for insulators, and TV coax for feed line. The only materials I really can't change is my feed line since I don't have access to 60ohm coax right now. Will the outer layer of the coax diminish performance on a dipole? If that is the case, should I go with a single wire fed long wire?
