Topband: Radials on top band

I can work anything I can hear on 160. That's the whole deal... If I 
can't hear it on the Hi-Z 4-square I can't work it......

I have a 45G 100 foot tower shunt fed with an Omega match of vacuum 
variables. I am always flat as the variable to ground is motor driven. I 
have 32 radials..... At this point the curve starts to become 
asymptotic. But, I still plan to add 32 more before the next top band 
season....

I've really enjoyed hearing all of the theory. It is in the books...all 
of it...

I have one book here entitled "Electromagnetics" by the late John Krause 
(W8JK, SK) of the EE department of Ohio State Univ. The book has all of 
the theory (if you can do calculus and differential equations) to 
substantiate the fact that 120 radials is optimal.... He goes way beyond 
opinions and assertions. All of his statements are guided by double 
blind scientific studies..

I had a quiz question at GA Tech eons ago. The question was "why is the 
sky blue"? You couldn't BS those guys there. It took 5 pages of calculus 
to answer it... It had to do with electrons going from one energy level 
to another....

Go get 'em on top band..
