Subject: Better Signal-to-Noise Ratio from a Combination of Improvements
including . . . a Ground

Thank ya, vury vury much...
MK - Hey I guess you are right, 'we' should all
pack-up our long wire antennas and sell our radios.
Oops That's a - no, No. NO !
No. Nothing wrong with using any type of antenna.
What is getting you into trouble is applying the technique
used with one particular type of antenna, and imply that it
applies to all. And also you are giving credit to the wrong thing
that improves the antenna you are using. It ain't the ground
in itself, or the transformer, which is almost never actually
needed. It's the decoupling of the feedline. The only reason
ground is mentioned is cuz it's the method used to help
decouple the feedline.

MK- Please elaborate. I am under the impression that:
1. A random-length "inverted L" wire antenna with coax lead-in is a good
choice for a simple, effective receive antenna for 1.8 to 30mHz listening.
2. That the matching transformer, with proper ground, is a simple,
practical, easy way to mitigate extraneous RF noise.
Is there a better single antenna that covers the HF spectrum? And what are
other ways to decouple the feedline?
Thanks,
Greg
