[TowerTalk] add a 3rd el to 40-2cd

[Raymond Benny]

About a year ago I was given something like a 403BA antenna, I was told.

I have had the Cushcraft 402BA in the past but never knew there was a 3
element version.

The antenna is all tied together in a heap of metal and have never laid it
out on the ground to see what it looks like.

My question, did Cushcraft make a 3 el version, or am I guess guessing?
Perhaps it's not a Cushcraft, but it uses much the same hardware and
insulators.

If someone knows, and there are plans, I'd like a copy.

Ray,
