Is the matching device REALLY a T Match? The HyGain Model 66B is actually a
Beta Match. The tubing of the match for this model is 56 1/2 inches long
ground to boom in the center. It does use a BALUN that is about 84 inches
long.
Element spacing on my model is 47 1/4, 40 1/4, 64 3/4, 62 5/8, 70 7/8. Used
mine for about 1 year, took it down and put up a 5el on abt 18ft boom that
is an excellent player (its a 6M5X design but different tubing diameter).
My HyGain 66B is now turning into an 8el on 37ft boom. BTW, the boom to
element clamps might be stamped with the number 12. Did not like SWR curve
of original antenna. New 5el has excellent SWR 100W forward, reverse
needle does not move (BIRD 43).
Hope this info helps.

If anone has 3 pair of these clamps they would like to get rid of I sure
could use them.

Subject: [TowerTalk] 6 m beam info needed
I have recently obtained a 6 el 6m yagi and would like to find information
on it. It may be a Hy Gain unit. The boom is 24 1/2 feet long and 2 inches
OD.. The boom to mast bracket is stamped out of sheet aluminum and would fit
a mast of 1 5/8 diameter. The element to boom brackets are also stamped
sheet aluminum clamshell type. The DE is split and insulated, with the
tubing slipping into plastic inserts in the stamped bracket. It uses a T
match with a 1/2 wave re entrant xfmr. The element spacings starting at the
reflector are 47, 39 3/4, 63, 62 1/2, and 71 inches.
I would very much like to identify the beam and , hopefully , obtain the
suggested element settings. 73, Dan, N5AR
