This audio file is a recording which Bill did when comparing an STL against a GP vertical & G5RV antenna.
The audio demo of the STL Signal to Noise Ratio as described by Bill:
"...STL’s have a better signal to noise ratio (SNR) than other types of antennas. Some years ago when I lived in San Jose, I ran a test on 10 meters FM with a station in the Seattle area. At the time the power line transformer behind my house was arcing and generating strong noise. I figured this was a good time to compare the SNR of my homebrew STL mounted in the garage rafters with a ground plane and a G5RV mounted above the house.
I recorded the test.
"At the beginning of the test I switched between the various antennas as the Seattle station was talking to another station. You will hear me announce the various antennas as I switched between them. Later, I transmitted to the Seattle station asking him to note the signal strengths of the various antennas. The second part of the recording documents his observation".
A complete, in-depth, article expanding on Bill's DRC meeting presentation, is in the January, 2017 issue of The Roundtable.
