Why not just convert it to a VB-66DX (Hy-Gain's model for 6L 6m beam, 24' boom)?

It uses a "beta" match, which is a "T" match, plus a balun, and works very 
well.  Essentially the same thing Telrex used several decades ago.

Details are: http://www.hy-gain.com/pdffiles/VB-66DX.pdf

Subject: [TowerTalk] hairpin matches


I recently acquired a 5 el HyGain 10m monobander on a 24' boom. The yagi uses a 
hairpin match. The plan is to convert it to 6m. Either a WVO special on 19' of 
boom or use the full 24'. Since it's already in place we are considering using 
the hairpin. Obvoiusly  shorter as the freq is nearly double 10m.  My friend 
W4HLR  will be actually doing the construction.
We would like to hear your experiences with HyGain hairpin matches on 
monobanders. Or any monobander.  Is there an advantage using a hairpin rather 
than gamma or other methods. DX-Eng sells hairpins & say they are better than 
gamma, etc.
We're hoping to end  up  with a heavy duty yagi as the boom & element sizes of 
this yagi are bigger & heavier than most  6m yagis.
It will be for  next seasons 6m Es. If there is one. Hi! Really was poor this 
Summer in NW Tn.

Tnx K9IL
