"zeno" wrote in message ... Seems like everyone I talk to about using ladder line to my proposed 540' horizontal skywire loop does a double take when I say I want to use ladder line into the shack. I was curious if there are any fans of ladderline feed systems who can relate positive experiences, or am I about to really court disaster here. The ARRL antenna book says that coax to this type of antenna is not as "multiband" friendly as was once fantasized....they recommend ladder line. Anyone actually have such a loop? What is your experience? Bill, K6TAJ I use 450 ohm ladder line on two seperate antennas here. One is a full sized 40 meter loop, in right triangle configuration, vertical. I run the line straight into the shack and into a EF Johnson Matchbox. Works all bands 40 thr 10 just fine. I run 600 watts into it, and no problems. No TVI, No computer faults, no telephone problems. On the other antenna I have a 140 CF doublet with 450 Ladder Line feed. This into a Heathkit SA-2040 tuner. Same same as above. The reason I am able to run the LL into the shack is that I have a large out building that I have the shack in. Run it right through, not a problem. Just keep the line away from conductive objects and I run it up to my ceiling then out. Dan/W4NTI |
