[TowerTalk] ID Beam Antenna

[Mark Beckwith]

Chuck/Don,

A DB-1015 does not have an 18 foot boom, and it has 3 elements only.  It's a 
really tiny antenna.

I don't know about the TH-4 but I had an old TH-3 and the hardware was not 
what we think of as "modern day HyGain."  If it has "modern day HyGain" 
hardware, then it is undoubtedly a HyGain, unless someone at some point 
cobbled together an antenna.  Do you have any photos of it you could post, 
Don?

Mark, N5OT
