[BC] Ground system

[Milton Holladay]

Peter Haas is the resident expert on KFBK, Franklin antennas,_etc._.  I 
don't recall whether the bottom of the tower is grounded or not.  ISTR 
that the FCC required a ground system be installed, but I don't believe 
it is used as an RF ground.
A Franklin is defined as 1/2 + 1/2 wavelength center fed.  Peter 
described some near-Franklins here a year or so ago in some detail; 
check the archive.
Judging by the frightening field strength  of KFBK, it doesn't need to 
be any higher than it already is..
Peter, pls jump in.......
