80/160 trap dipole question - last one I hope
 

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".

I can't answer the BW / efficiency question, but the above answers it's own
query.....
