[TowerTalk] What am I missing....balun

[Wes Stewart]

Not defending this at all but... there shouldn't be any, or close to no 
attenuation.  It's a short length of high quality coax.  Since they claim it's 
built to customer specifications, and they don't quote any, maybe the photo 
shows how it would be built, not an actual balun.
