hi there..

think i will put my pennys worth in here...

do away with the long wire altogether..you will proberly never get rid of
the rf in shack etc..due to being too high above gnd..i know i have tried..i
live in an apartment (3rd floor)..no garden or land..i have tried end feed
long wire from balcony to lamp post etc..rfi to phones stereo etc..BAD

i tried all the tricks in the book no go...
SO.. i chatted my neighboors up and have been using successfully for 4 years
now a full sized 10m-80m diople (trapped with 40m trapps.)its slung up at 3
points in the shape of a triangle each courner on someone elses
apartment..the coax feed is rolled up 6 times 6inches dia just before diople
feed point..i have hung seperate dioples for 18mhz.28mz below main diople to
help on those bands ..
i have had NO tvi/stereo i/ phone i etc atall (touch wood)..i am using full
size diople but not out straight so you could too, espically as you have a
garden!!!
and have worked much dx all over the world with 100w ssb...

so if you give up with the long wire (as i did) try this..its cheap too..and
the antenna is in about every antenna handbook..)

Any ideas would be GREATLY appreciated.


To effectively avoid RF in the shack, the differential currents need
to be balanced (equal in magnitude and 180 degrees out of phase). It
is extremely difficult to do that with an inv-L. I had good luck with
a dipole even though the shack was under one end of the dipole. I
brought the ladder-line off at right angles for about 50 ft then
routed ladder-line back to the shack from there so ladder-line
parallel to the antenna was always about 50 ft away from the antenna.
