Model No: 6-30LP11 

FEATURES: 

 

The 6-30lp11 log periodic is a modern design both mechanically and electrically.  Top quality materials combined 

with many CNC machined parts will keep it trouble free for years or operation. Performance is excellent and specific path 
gain can be as much as 12 dB with ground gain factored in. The 6-30LP11 is available individually or in a turnkey system, 
complete with support tower, rotation mechanism and controller. Many options exist within the turnkey system such as 
height and type of tower, rotator mechanism, and controller type. As pictured above and originally supplied to NASA at 
Edwards air Force Base in Edwards California, the tower was a special, massive, motorized, self supporting 72 foot tower 
supplied by US tower Corp to M
