[SixClub] vertical antenna(directanswer)

[John B Dougall]

John,

Does the 98.425 feet computation consider bare copper wire or PVC 
covered? What guage of wire and thickness of insulation if any? Does it 
consider the 0.95 velocity factor? Does that tune to the lower end of 
the Band? Does it consider any one of so many other factors and constants?
Did you ever learn that little knowledge is worse than none? Did your 
exercise make you look into any books or other info sources for some 
theory background?
On the other hand, a long wire is just a long wire! That is when and why 
antenna tuners come into the picture. An alternative to a tuner, which 
should also provide better efficiency like that of power transfer, is to 
trim the long wire for a best match on the band portion required. This 
could be a long-winded and repetitively elaborate exercise but well 
worth the time put in it.
Please, let us all try to keep our professional-like 'amateur' spirit 
going strong.

73,
