One leg of my trap dipole ran nice and high between
two trees, The other ran to a telephone pole but in the process of installation, it caught halfway on a roof tile and ended up with the trap about 13 feet high. The other trap is about 30' up. I fixed the situation and now both traps are even. It had interesting results: 160m resonant freq went up 50 kHz. 75m resonant freq went up 75 kHz 2:1 swr bandwidth on 160 got smaller by 20% 2:1 swr bandwidth on 75 got larger by 10% Am I correct in assuming that the smaller b/w on 160 indicates better efficiancy via higher Q? It already works pretty good, I made a dozen contacts out to about 800 miles on 1975 last night with 50w and that was with the east trap @ 13'. I don't know really how good that is but everyone I talked to was impressed at how good I was getting out with "a trap dipole and only 50w". Ken KG0WX |

Ken KG0WX I can't answer the BW / efficiency question, but the above answers it's own query..... 73, -- Steve N, K,9;d, c. i My email has no u's. |
