[TowerTalk] Baluns

[StellarCAT]

Anyone familiar with and have experience with the W2DU baluns sold by UNadilla? 
Specifically the ones with the built in lightning arrestor? Will this short with a strike or
 is this not a problem? I was told it is actually not an arrestor rather it is a suppressor - 
bleeding off the charge... it will be at 140' and I do not climb so I need something there 
that should be reliable... comments? [not interested in a coax loop - thinking this balun 
for now]
