[VHFcontesting] Cushcraft 13B2 Match

[David Pruett]

This would be very difficult to implement mechanically.  A Beta-Match 
(also called a hairpin match) requires a split driven element (insulated 
from the boom and split into two halves like a dipole).  The 13B2 driven 
element is one continuous piece of aluminum tubing, with T-match bars 
connected by straps to the driven element.

The driven element would have to be split and an insulated mount 
fabricated which will be rugged enough to hold the whole thing 
together.  Not an easy task.

I recently got one, but it was missing all hardware and the match (basically, it came with boom and elements only, including the DE with the T-match pieces parts).  I feel like it should not be hard to build the match but I don't know what the balanced feedpoint impedance is supposed to be.
