At least this topic has injected some interest into
the LF scene. LF activity around Europe has virtually died, in fact at
present it is a dead duck.
My comparison between loops and verticals is
based on an open clear site and qualifies the merit of the antennas and NOT the
environment that that you live in.
I do not know anything about a vertical that leans
up against a pine tree or a loop hooked over trees and bushes. I think anyone in
that environment would be at a big disadvantage engineering a LF antenna
When I visited Long Beach California some years ago
and met W6AM and his friends they all had acres of land covered in rhombics and
naturally I thought all USA amateurs were in a similar situation, it appears
that I am wrong and things are tough on the East Coast USA when it comes to
space for LF antennas.
I suppose in some cases some sort of antenna, even
a loop is better than nothing.
Did I read somewhere a while
back that using a small loop the antenna current would be 76 amps
for 1W of RF erp output, If this is the case the atu components
and wire would MELT, so it would not be practical. Using a modest
vertical around 100 feet to get the same output the antenna current would only
be several amps.
I was intrigued reading the opinions
of those interested in this discussion, and what a response.
