Anyone have more info on this hobbit ATV antenna I bought? Has NSN nimber

Hi everyone. Seeing how vast the knowledge base is here I thought I’d give it a shot. I recently bought this antenna from a seller in Europe. It says it’s called the hobbit ATV military antenna. But the guy does not know the spec or brand of this particular antenna.

From what I can see it could either be US or U.K. made. NSN designation 5895-99-333-0123. It appears to have a N-type connector at the end.

Can any any one have a look at the photos below and tell me some more information? Eg. freq range, compatible base, and manufacture. Thanks in advance!

I don't have great info, but here's some info...

It's sourced by the UK. Manufactured by "Selex ES Limited.". Below are some alternate part numbers:
9RO-0537/01
DD50-31-00-100
P50310000

There's also a part number under the manufacturer "MINISTRY OF DEFENCE FORCE PROTECTION INTEGRATED PROJECT TEAM F"
FP72

It's only been around for 10 years; the assignment date is 12/10/2008.

Thanks. Do you have a web page or documents on this antenna? I tried looking up the part number under selex es limited and cannot find anything at all.

Also found two pictures of this antenna mounted on the ATVs its intended for.
