I think, reading Joe Carrs "receiving Antenna Handbook"
that doubling the antenna length
results in a 3 DB ( barely audible ) increase in Signal strenght..
4X length = 6 DB gain

Shortwave signals ave Very very weak;

Some have had luck with Very Long antennas
- Heres a link to " beverage" antenna articles;

I've tried "helical" antennas and I find them to be so directional that
at times I felt like I was doing tai chi with the pole just to get a
readable signal. What "bugrunner" needs to do is strip the insulation
off one end of the wire (not much, maybe a half inch) and attach it to
the TOP of the whip (where the end is). If that doesn't work he needs to
consider wire position-a N-S wire will behave differently signal wise
than a E-W wire.

I have played with the dx/local switch, and I only use the radio
after 9pm. I will try the coax cable, I have a lot the cable guy left.

Look at the DX / Local switch..
- Else try at night, Propagation is better then..

Feed the antenna to the radio via a Coax cable ( radio shack grey shielded
coax
)
works for me..

Hi,
I recently purchased my 1st SW receiver, a Sony 7600gr. Not knowing
much
about the hobby I did not purchase a antenna. I was hoping the whip would
be
adequate. Well the whip does seem to pull in a few stations in the
5000-9000
range, but little else. Additionally the signal strength was not as good
as
I had hoped. I attached about 24ft of light gauge speaker wire to the
whip
and tossed the loose end out the window into some low bushes, and did
gain
some signal strength. Trying to improve the reception a bit more I added
50ft more speaker wire to the 24ft, but the new wire is a heavier gauge,
18
I think and the first wire is 24. At this point I tossed the wire as far
up
a backyard tree as a could, about 40ft. In all honesty I must say I don't
think I have gained anything with this additional wire. Could it be a
problem going from the heavy wire into the smaller wire then to the whip?
Would I be better going to the whip with the heave wire and attaching the
lighter wire to the other end? Would I gain anything by building a
broomstick antenna with the wire I have instead of hanging it from the
tree?
Or is it better to have the wire exposed to as much of the outside as
possible such as it is now?
Thank You.
