Wow, I haven't seen one of those in probably 25 years!

They used to be popular, though.

Unless someone else copied the design, it's a 70cm collinear beam made by J-Beam Aerials LTD in the U.K. I believe they're out of business now.

It was a very good antenna.

I agree it's a Jaybeam, maybe a MBM 88, least it looks to me like that on it had 21 X elements

If you operate 70cm SSB-CW, you have a use for it!!

If you don't, then probably not.

Even if you don't have a use please don't scrap it! I'll cover the scrap price plus shipping to prevent that. The MBMs had very different construction arrangements. The drivens were slots with yagi element as well as the Xs.

Bandwidths were wide: That is 432-450 complete. The company that made them was mainly a TV aerial producer but the founder was very clever and marketed to hams as well. Some of our friends in the UK would likely know the story better.

Yes, the Jaybeam is no longer made.
I think Spectrum International imported these from UK until early 1990s,
when company changed hands and new UK owner stopped production.

I still miss the 8 by 8 skeleton slot for 2 meters made by same company ...
I had a line for one in Ohio (in a barn) a few years ago.
OM did not want to ship it. Likely now metal scrap (sigh)
