Kill any more Mexicans last night? Any blood on the axe handle you keep

* SWL Longwire
* Low Noise Antenna Connection
* Grounding Is Key To Good Reception


John Doty will tell you that he did not Invent any of these things
or Uniquely Combine them to Create a New Concept. *He more
or less studied what was out-there and empirically tried things
until he found what seemed to Work : "The Best". *He Wrote about
them; and Help to Popularize them in the 1990s in the Shortwave
Radio Listening (SWL) community. *As far as I know he makes
no claim that any one of these things will work by itself -but- as
a group they do improve things greatly over a simple Classic
Horizontal Bare Wire Antenna with an Insulated Wire feed-in-line
-or- an Improved Horizontal Bare Wire Antenna with a Coax Cable

Well thats just to bad. I don't care what you think. You never
contribute information here. You are a member in very poor standing.

As long as I'm not as obnoxious and strange as you I'll be OK.

When is the last time you made an on topic post? A few months ago last
year? Maybe one or two at most.

Do everyone that reads the news group a big favor and go someplace else

* Better Connect {Bond} the two Ground Rods at each end
of the feed-in-line.
* Be a Better Ground Radial in the Ground then the Coax Cable
