[TowerTalk] RE: long transmission lines

[Tom Rauch]

I have a 1400 foot long open wire feedline made from number eight 
(or six, I forgot) copper spaced 2.75 inches. It was fed through 
transformers, and was reasonably flat from 1.8 through 30 MHz 
when terminated in 50 ohms at the far end coaxial output.

It has about the same loss as 100 feet of RG-213 cable on lower 
frequencies.

I abandoned using it because it radiates too much above 14 MHz 
(not enough twists in the wire) and it is too difficult to maintain (it 
runs through my woods).
