ID this mobile antenna please

[N9JIG]

Can anyone definitively identify the model number of this antenna? I have had it bouncing around for years, perhaps a couple decades. I recently did some testing on my car and it measures out the best of all the antennas in my stable on both 2M and 440.

It is 17 inches tall, with a really thick radiating element on an NMO base with a 1/4 fine thread.

I have a Larsen NMO-2/70sh that looks extremely similar to that, but the base is different. The cone and whip look identical. Same length, same color, etc.

I think you are correct, it sure looks like this one.

Thanks!

That's not it, different whip interface.

Yeah, I think you are right on second glance.
The base on my antenna is all brass, painted black like everything I have read about the Tram, I wonder if it is an older version. Any labels came off years ago.

It sure works well though! I want to get a couple more, mobile antennas don't last long in the desert heat!
