[TowerTalk] Mystery Tribander 2

[Roger K8RI on Tower]

A reflector with two traps (one on each side) is consistent with the 
seperate 10 meter reflector, but that three traps started me thinking last 
night as well.  I don't know of any older antennas that would have 3 traps 
each side of the boom. OTOH one of them *might* be a loading coil.  Still, 
I've not seen anything like that.  *Maybe* parts of two antennas have made 
it into one.

I have an ATB34 and an old TH-4 out in the shop... Or did I give the TH-4 
away?  Guess I'm going to have to check the Aluminum pile again.

I'd really like to put up something that would cover 40 through 10 with at 
least 3L on 40, but I don't want to pay four grand to do it either.
