Title: Antennas?
Post by: N5RWJ on November 18, 2011, 09:02:33 AM
What SWL antenna do you use?

I use the same antenna I used to my ham activities -- an 80m doublet fed with window line to a balun.  It works quite well.

I also have a PAR-end fed SWL antenna, but it picks up a lot of noise compared to the doublet.

In the past, a 75 meter dipole - 119 feet total. Apex 33 feet - ends 10ft up.   73 David K1WJ

As a kid I used a loop of wire near the ceiling in my room. Now I use a smallish inverted L outside. I also have a fan dipole but the non-resonant L tends to work best for MW and SW listening.

W3EDP fed through coax and a 9:1 unun earthed. Same as for my ham activities.

G5RV ends oriented NW & SE.  Picks up everything except S. Africa just fine.

 Hi All,

I use a 75 ft long wire which I "force" to work from 7 Kc all the way  up to around 20 M. From there the 10 M slope dipole takes over.

I have a 200 foot wire hung from one tree to another.  Years ago I got a booklet from (if I remember right) Radio Australia.  It described dipoles that listeners could construct for different RA transmitting frequencies to help one receive their broadcasts, and the approximate direction that they should be hung for optimum reception, based on the location of the listener.

I use a 300' long wire antenna with a 9:1 balun, from the back of my garage straight back into the woods. It is supported my multiple tree branches. I used a bow and arrow to string it over the trees.

 When I was about 10 years old I ran a piece of 14 gauge wire from my 2nd story bedroom window out to the garage about 60 ft away. It worked great with my old S-120.

I share my wire antenna 66 ft long, 8 ft high with my HF radio for Shortwave Radio Receiver.    since it go through antenna tuner, I can tune for best receiving,  I often use my $100 SW receiver to listen to HAM band, sensitivity is almost as good as my HF rig.

Has anyone use a CCD Antenna, what is your opinion of it?

Two 2-wire switchable-direction Beverage antennas. The ultimate SWL antenna.  :)

Multiband DX-SWL slopers, a G5RV, trapped verticals and dipoles, the assorted random wires. One day I'm going to put up a couple of log periodics for both ham and SWL usage.
