[TowerTalk] 160M inverted L

[ersmar at comcast.net]

Alan:

     An easier solution might be to install three sloper wires, one for each band.  The issue then would be where to tap the tower for optimum performance (insert your own definition of optimum here).

     Check out the TowerTalk archives for several weeks worth of threads on the subject of slopers beginning with the Jan 1, 2002 (last year's) postings.  IMHO that was one of the best (my definition: most educational and practical) postings I've ever read here*.  I followed N4GK's et ux advice and was able to construct an effective 80M sloper on my tower that already had a 160M shunt feed on it.
