I was looking at a 4 el "trapped" horz ant,that is dissembled
.................hy-gain,mosley??
any ideas where to look for a "print"
thank you

Photos will save significant time here and reduce guessing. A picture is
worth a thousand words.
Were there any color bands on the boom?

Here is Mosley's web site:

Cushcraft has almost all of their assembly / instruction manuals on the web
site:
www.cuschcraft.com

MFJ / Hy-Gain also has many of the manuals for the later antennas on the web
site:
www.hy-gain.com

If one of the four elements doess not have a trap, it could be a Cushcraft
A4. Mosley antennas that I have seen put two traps in one housing; so, it
looks like there is only one trap per element side unlike the HyGain and
Cushcraft that have two. Offhand, I can't think of a Hygain 4 element
antenna with traps. I don't know if www.cushcraft.com still exists. You can
get to the Hygain stuff from the MFJ site.

You are going to have to look very carefully at construction details to determine brand, and then at various differences
due to age to identify the specific model. Then go to the URLs listed for drawings. Just yesterday I was asked to sort
out a 6 element antenna, which turned out to be a HyGain TH6DXX with several TH7DX repair parts. The original TH6 boom
to mast hardware was notoriously weak, and was often replaced with the later, stronger TH7 assembly, but the
documentation on that modification is very obscure on the 'net, so the relatively inexperienced (re-) assembler was in a
quandary about the model, and consequently the dimensions.

In spite of other misinformation you have been provided, HyGain built a 4 element trapped antenna, the TH-4, sold in
several versions between about 1956 and 197?. See another posting 11/09/04 on this ng asking about one.

I think it was shorter lived than that. I have 1962 and 1964 ham catlogs,
the TH4 is in the 62 (no picture), but not in the 64. By 1964 the TH5 was
out. That is not to say they were all sold by 64. I should have mentioned
the Explorer 14, which they call a 4 element antenna, but to the casual
observer looks like it has 6 elements.

BTW, Hygain no longer comes up on the MFJ web site. Anybody know if they
sold it?

Hy-Gain (MFJ) web site is working fine for me:

I know hy-gain.com works, but you can't simply get to it from
mfjenterprises.com. Used to be able to. If you type in Ameritron or Mirage,
they come up with several choices. Hygain and Hy-gain give you no match. I
did finally get it to work by searching on "rotator", and then clicking on 6
meter beam. This shows Hygain at the top of the page together with
Ameritron, Vectronics, Mirage, and MFJ ( I am not claiming this makes
sense). If you click on "antennas", you only get the MFJ.

Tam -

Yes, I noticed this a few months ago.
I also noticed the problem with Ameritron amplifiers at one point - but this
may have been changed.

I wish to thank ALL....I will go back and look @ the elements and try to
decipher what it is...2 of the trapped elements are exactly the same length
and look identical...........NO color coding.............it has the square
horizontal "wire"connectors between the elements..I only see 3 clamp points
for the elements to the boom....., But the owner said all 4 were attached
when he took it down,,,,,,,,,,,,each element is fully assembled ,,,,,,,,,
the elements have a sweged size reducer near the tips......some of the
traps are about 3 inches in diameter, some are about 1 1/2 " diam..
it approaches looking like the TA33mu arc
the search contionues,
carl
thank you

==============================

Carl -

You will find that MFJ/Hy-Gain does not have all of the manuals on-line
(e.g. TH-4 model). Unfortunately, the manuals/documentation for early or
short lived Hy-Gain antenna models are not in the possession of MFJ/Hy-Gain.
These were likely lost in earlier ownership changes or accidentally thrown
out through the years.

This is not a problem unique to MFJ/Hy-Gain. Bencher had a similar problem
with early documentation after its acquisition of Butternut antenna line
from the previous owner.
Cushcraft does not have manuals for some of its very early vertical and beam
designs (short lived).
The owners of these antennas could perform a service to the amateur
fraternity and send copies (or PDF scans) of their documentation to the
current owners, with the stipulation that it be posted for all.

It would probably help if you posted the length of the boom and the length
of the longest element. Are you saying there are two driven elements?
