[TowerTalk] HFTA and diferent bands antennas

[Stan Stockton]

Jorge,

HFTA assumes nominal gain figures for antennas containing a certain  
number of elements for a certain band.  It does not model the  
performance characteristics of a particular antenna design for those  
antennas or other structures of different lengths like antennas for  
another band.  You would have to use EZNec or another NEC based  
program to do that.
