[SECC] QRZ South Carolina 160m?

[Tom W8JI]

Your antenna does not sound too bad. You should be within a dB or two of a 
full size antenna, unless you have the antenna jammed up in the middle of a 
bunch of other stuff that is sucking up the signal. The worse performing 
stations I have ever seen are those with too many antenna just randomly 
placed and too close together. Power might be worth a dozen dB, but having a 
dirty antenna installation with poor wiring and unwanted coupling to RF 
absorbers can be devastating. It's damn easy to lose 20 dB in an antenna 
system that is poorly planned, especially a cluttered system with too many 
antennas too close.

160 is especially problematic for poor planning, because a wavelength is 
over 500 feet. That means you have to pay attention to anything within 500 
feet distance of the antennas. Remember 130 feet of spacing on 160 is like 8 
feet on ten meters!!!

I remember years ago in Toledo on 160 with a local friend who lived on a 30 
by 120 lot in the city. He had a simple single low band antenna, a Zepp for 
80 meters 50-60 feet high. He would always be within a few dB of my 1/4 wave 
tower that sat on 100 radials in soaking wet black sandy loam swamp soil. 
This happened countless times.

One local ham had a back yard that looked like Radio Free Europe. He had 
Yagi's and Quad and verticals and dipoles all over the place, with his 160 
antenna in the middle of that mess. Old Harold used to beat Mr. Antenna Farm 
by 10-20 dB all the time, and he did it on all the lower bands.

Mr. Antenna Farm could not believe he got skunked by such a simple setup, to 
the point where he went purple-faced nuts telling poor old Harold he was 
running illegal power and all sorts of stuff. We thought his eyes were going 
to pop out of his head!! Poor Harold only had a pair of 6146 tubes in the 
final.

If you can hear them you should work them, although 100 watts does make it 
more difficult.

We work hundreds of low power, small antenna, DX stations on 160. Very long 
distances are possible even with low power and small antennas.

The common limit on 160 is always hearing the DX, unless your antenna is a 
mess.
