1. [TowerTalk] Open wire transmission line (score: 1): Author: Steve <steveac@charter.net>; Date: Wed, 21 Sep 2005 22:28:01 -0400; I'm thinking about constructing some open wire transmission line, probably 70-80 feet in length. Probably #10AWG or #8AWG soft drawn copper. L. B. Cebik's web site http://www.cebik.com/gup/gup31.html; /archives//html/Towertalk/2005-09/msg00658.html (7,947 bytes)

I guess a lot depends on the mechanical tension in the wires. You might be able to get away with greater spacing.... Strips will offer more resistance to; /archives//html/Towertalk/2005-09/msg00660.html (9,577 bytes)

Alternative: Buy some 1/2" or 3/4" ABS irrigation tubing, cut it into approx 4"-5" long tubes, and use a hot knife blade or screwdriver; /archives//html/Towertalk/2005-09/msg00661.html (9,948 bytes)

You can run into problems if the load impedance is very high at high power. On humid; /archives//html/Towertalk/2005-09/msg00666.html (8,106 bytes)
