Help identify 3 ele beam
 

I bought a 3 element trap yagi antenna that was disassembled. I was told
it was a Hy-Gain model. After laying out the parts I can see that it
doesn't look like a Hy-Gain model because of the following:

1. It uses large diameter, single traps. These are identified with color
coded lables (red, green and blue - radiator, director, etc.)

2. It doesn't have a "beta-match" - rather, it looks like the driven
element is directly connected to the coax. The mounting of the driven
element is almost exactly like the Hy-Gain style with insulators that
are mounted into a clamp that surrounds the boom.

3. The director and reflector use boom mounts that are different than
Hy-Gains. The mounts are made from aluminum extrusion and use a circular
opening to mount to the boom and have a wide, flat top that the element
bolts to.

Does anyone know what make and model this 3 element beam is? After I
'ID' it I can then get the assembly instructions so I know what
dimensions to set up since all of the joints on the elements are
"sliding joints" with clamps,

Thanks for the help,
Henry W7YBS

This is exactly like my old Mosley TA33Jr. Not at all like the HyGain TH3.
Ditto for #2. On my TH33Jr, the elements were mounted via aluminum blocks
with little U bolts. If it is Mosley, the length of the boom will be a
giveaway as to which model. I would try to download some manuals from the
Mosley web site; it might be mosleyelec.com.

Henry:
What you have is an old Wilson antenna, most likely a System 33.
There are some manuals on the web, but I don't remember if this would be
one of them.
Majestic Communications here in Memphis bought the Wilson line many years
ago.
They have a FEW parts left, but they should be of some help for a manual.
Try 901 / 794-9494, and don't let them know I sent you!!!

Unless Mosley has changed their policy they do not have any manuals on their
web site. A local ham tried to get some emailed from them and they would
not do it, but would sell him the manuals.

Couln't find manuals at the Mosley site URL:
http://www.mosley-electronics.com/

But BAMA has the manual for the TA33JR

Thanks for the help. The antenna is not a Mosley. I used to have a
TA-33Jr. but this antenna is much larger. KW rated traps at least. I'll
go with the Wilson SY-33 answer and see what I can find out. Thanks.
