Antenna Wire Size W0RPS 2 weeks, 1 day ago

I currently recommend the use of #14 wire or larger, as it is a National Electrical Code requirement. I used blue house wire for antennas up in the air and green wire for wires closer to ground level.

In practice, the wire will break due to normal mechanical stress before it can't handle the power--as the power is distributed over a very large heat sink up in the air--as anyone can tell you if they have tried to solder wire outside with a small soldering iron.

CW question randallk 3 weeks ago

Many radios, including your Alinco, come with electronic keyers. You may need to change a menu setting on your radio to accommodate a straight key.

Doublet Type Antenna on my Garage KG6SYX 3 weeks, 5 days ago

At higher power levels, you should use an insulator and properly support the antenna away from the roof--it is possible to start fires when running high power when the end of the antenna is in contact with combustible material.

I'd suggest contacting William M. Kendrick N6RV
n6rv@arrl.net
He is the Technical Coordinator for Los Angeles--he may be able to put you in touch with a local expert to advise you on how to best install your antenna.
