Hello all--Im new to the site---i am thinking of buying a 2m 26b2--but wow the cost !---the match harness seem to me expensive---are coax the lenghts as crictical as i think they are to make a harness-----also the quailty difference the> -13b2 -and the hygain vb214 fm -they both can do vertical and horizonal --Yes??? thank you -- craig-- n2ydh
The 26B2 is a pair of stacked 13B2s. The antenna cost is only a small part of an overall installation, since you need a strong rotator with a brake, a vertical mast, a cross boom (if you're using them vertically polarized for FM), and something strong enough to support all of that.
It's not a bad deal. A pair of VB214FMs would work as well; those are optimized for FM use (dimensionally) but they won't "roll off" much if used at the lower end of the band. The mounting bracket allows for either polarization.
The harness is critical, but can be homebrewed if you wish. The power divider is just 1/4-wavelength (electrically) of 75 Ohm coax per branch, joined with a coaxial "Tee" adapter. The cables from the antenna driven elements down the booms to the "Tee" adapter are 50 Ohms, whatever length reaches, but must both be exactly the same length.
