[TowerTalk] Ladderline. What Kind ?

[Jim Brown]

The classic literature is full of practical instructions to build ladder 
line. ARRL Handbook, ARRL Antenna Book, RSGB books, etc. 

I have made spacers by cutting 1/2-inch PVC electrical conduit into short 
pieces, then drilling holes for the conductors to pass through. There are 
many other ways to do it. The equations for impedance vs wire size and 
spacing are in those books. I just toured a coast radiotelegraph station 
(KPH), built in the 20s by RCA, where transmission lines were constructed 
of wires under tension between support poles that were perhaps 20 ft 
apart. 

Email lists should be an exchange of ideas, not a substitute for studying 
the basic references and textbooks!  Jan gave you a good idea. You should 
thank him, not berate him.
