Topband: Tribander traps

[Herb Schoenbohm]

Herb,


It is not an easy job as the interior insulators may be brittle and 
break.  I did the clean out exercise to several tri-banders, A Hy-Gain 
Explorer 14 and a Cushcraft A3S.  I found bugs, even a lizard in one 
trap.  I clean the connection to the element from the trap and replaced 
the set screw with a stainless steel one after putting Penetrox to the 
aluminum strap.  One thing I do not like about triband beams is the 
inability to cover the entire band with a VSWR below 1.5 so I finally 
made the decision to replace the triband(s) with a three element Cubex 
Quad and it was worth the effort both in total band coverage and over 
all performance. As a result I have a large box of tri-bander traps in 
the corner for both antennas which I was going to put on eBay.  Some of 
them do not have the protective end caps which were discarded because 
they were also brittle from years of baking in the tropical sun. Let me 
know if you need any of these traps.

Good luck with your project


Herb, KV4FZ
