[TowerTalk] Vertical with 1 radia

[pehaire]

I do not know how I got into this.  I guess I am not making myself clear.

All I am saying is that a good operator at 3DA0 and 4S7 (12,000 miles) can 
hear my 50 watts and shunt fed tower with radials on 40 cw.  And they were 
able to copy a signal report (5 characters).  My signal may have been down 
many dbs below other signals.  But the operators pulled me out.  Operating 
skill does not get all the credit it should.  I am too old to have any skill 
left, but give the guy at the other end some credit.


I am sure there are antennas that would never make the contact.  I have a 
friend 5 miles from me that has a 250 foot horizontal loop 15 feet off the 
ground that I don't think would make the contact.  He would probably have 
better luck with a long string and a pair of paper cups.

Skywave propagation varies too much, even during a time of only one or
two seconds.  You have to do the testing over a ground wave or space
wave (line of light) path.
