Title: tri bander identification Post by: KB5MD on October 25, 2020, 04:28:38 PM Several years ago I received a three element tri-band beam from an estate. I recently decided to assemble and use it. There is no paper work with it or anything on the internet that I can find.
I have searched Hy-gain, Mosely and Wilson all to no avail. What I would like to know are the names of any other manufactures of antennas for the ham band. The antenna is about the size of a Mosely TA33 and has the single traps on each element like the Mosely but the similarity ends there. Any info would be appreciated. It is difficult to find information on something when you don't have an idea as to what it is. I believe the antenna is about 12-14 years old.

If it is a match, I can tell you the various dimensions of how mine was set up. The three elements have been removed from the boom but each is still fully assembled and setup from where they ended up at final tuning. My email is good on QRZ or you can PM me here on AMFone. If any one else needs this info, I will post here.

Chris AJ1G Stonington CT From initial post: "size of a Mosley TA33 and has the single traps on each element like the Mosley" Cushcraft A3 and A3S beams use two trap housings on each element.

Title: Re: tri bander identification Post by: wa6mtz on October 26, 2020, 10:31:27 AM There was one called a Hornet.
It is an old one and appears well built traps. Title: Re: tri bander identification Post by: Pete, WA2CWA on October 26, 2020, 03:26:42 PM There was one called a Hornet. The majority of the early Hornet tri-bander line had egg beaters on the end of each element. The amateur antenna line eventually moved to Swan where the egg beaters were removed.It is an old one and appears well built traps. Here's one of Hornet's last tri-banders. It's 4 elements but they also made a very similar 3 element.

I had one of these beams when I lived on Long Island. I had it up 70’. Kind of heavy. It worked well.

The Mosleys have a bar underneath the center of the driven element. The Wilson does not. |
