Model No: KT34M2 

FEATURES: 

 

The  KT34M2 is now the best performing and strongest short tribander available today.  All four elements resonant 

on each band.  A dual driven element allows a beautiful flat match, broad gain, and high front to back curves across 10, 
15, and 20M.  A 3kW 4:1 balun efficiently matches the antenna to 50

.  All sheet metal parts has been upgraded to our 

new machined shorting bars, stiffening and strengthening the antenna noticeably.  The long term performance is en-
hanced by the total contact machined joints. This antenna will be competitive with most monobanders! Be surprised, get 
the NEW KT34M2.
