[50mhz] HyGain 64B question

[Wayne]

 I have what may be near the same 4 element beam.
 I downloaded a manual for one almost the same, and found dimensions to be
the same.
 Mine still has the old coax balun on it, nice low SWR.
 Manual shows dimensions for a replacement for higher power usage.
 Problem is, it calls for plain polyethylene dielectric, and most available
is poly foam, which changes the velocity factor, thus the actual length
needed.
 I'd suggest you download the manual and use the info there.
 This is assuming it is the same or similar.
 Mine works well, but I need to replace or seal the coax on mine, as the
exposed dielectric is cracked.
 I also considered making a trombone type gamma match for mine (simpler in
the long run) but could not find what I needed for parts at present.
 I have a 5 element homebrew 2 meter beam that uses this type of match, and
it does very well over the whole 2 meter band.
