[Antennas] Balanced line optimum conductor spacing?

Sat, 05 Jan 2002 15:49:38 -0600

Back in the late 1940's and early 1950's mycalex was used for spacers.
The rule of thumb was 6 inch spacing with #12 wire was 600 Ohms,
4 inch spacing equaled 400-450 Ohms.  Back then I used a 250 foot
center fed with 6 inch spacing and it worked great on 160 and 80.
