[TowerTalk] [Bulk] Re: antenna choices for K4XS

On "Low Performance Trap Antennas" :  Is it really known what is the cause for the apparently very large difference between a correctly designed trap beam, say a TH6DXX or similar and one of the not so good performers?  Trap loss can't be a big part because even relatively low power loss at a given trap, say 50 W, will burn the thing very quickly.  Assume 3 elements, 6 traps that get exposed on a given band and -3dB gain compared to better beam, this would be some 1500/2/6 watts, a lot of watts per trap.  Even it not this much just loss, there would be ample power to melt the insides of the trap.
