As man-made noise levels become ever more problematic for radio amateurs,
particularly those that are serious about weak-signal DX on the lower bands (160
/ 80m), the ‘Loop On Ground’ or ‘LOG’ is proving to be a worthwhile improvement
for some.
Bud, VA7ST, near Kelowna, has done some recent experimenting
with a LOG as an alternative to listening with his 160 / 80m transmitting
antennas and has written a great blog on his findings.
Bud has included
some ‘A-B’ tests comparing the LOG to his normally-used vertical or inverted-L
and the results are quite interesting.
If you’ve ever considered building
a separate quieter low-band antenna, you can find everything you might need to get
motivated as well as a nice listing of LOG-related links in Bud’s very helpful
blog:
