[Elecraft] Antenna wire gauge efficiency

[Paul Kelly]

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
