Paul, I am certain you will get more responses, and since I do not have the
formulas in my head, I suggest you wait for the more knowledgeable folks to
weigh in. However, if you plan on going up into the hundreds of watts, I
would be thinking in the 14 gauge area. Personally, my antennas are 12
gauge, but that was because ...
A) I used it as much for its added strength as for its electrical
characteristics ( I live in heavy woods)
B) It was the wire I had lots of on hand. (Application of the Cortina
Economic Applications of Existing Resources)
One more thing I might add is that in case you had not planned on doing
this, use a system of pulleys (I use marine pulleys) so that as the trees (I
assume you are erecting the antenna between trees) sway, the antennas will
give. If you need more info on this, contact me off list. I will be happy
to send you a graphic of how I do this.
Best of luck.

Subject: [Elecraft] Antenna wire gauge efficiency
Hello all. I know this is somewhat off topic, but there is a lot of
knowledge here, so I will ask. I am in the process of erecting two wire
antennas and wondered, for stealth reasons, how small I can go in wire
gauge for these antennas and still have an effeicient radiator. I know in
general bigger is better and copper glad is prefereable. I will be
running anywhere from QRP to 400 watts. It seems like I have seen tables
in the past that are good general reference guides for this question. Any
thoughts and yes my K2 is a great rig? Paul NN5G
