Antenna ID

[JoshuaHufford]

I was given these 2 antennas with no info about what they are. One is a standard NMO mount, the other came with a magnetic base that isn't NMO.

Thoughts?

UHF, probably high split 450 to 512 MHz

I can't help you with identifying them, but I have one similar to the one on the left. It has a few more coils on it, which shortens it about an inch from the one in your photo. Got it for a couple of dollars at a hamfest and thought it might work well on my scanner for VHF high band. It seems to work decently for that. The nice thing about it is that it's much more light weight and less visible than the older magmount that I've been using for years.

If I had to guess, I'd say that the one on the left (open coil) is a typical, off-brand 2m/70cm ham antenna - they seem to be pretty common.
The one on the right (encapsulated coil) looks just like one I have around here somewhere, with the coil unusually low. I never confirmed what mine actually was, but always suspected that it was for 220MHz.
If you know anyone with an antenna analyzer, you could know for sure.

The one on the right looks like a V/U/800 scanner antenna to me. Left one looks like a dual-bander.

Have similar to the one on the left, purchased from Amazon in 2021, "TRAM 1185 dual band magnet mount antenna". Like MiCom I use it as a scanner antenna, in agreement with his thoughts below:

+1 on the left being that Tram model. The right one looks like a Laird triple band antenna. 150/450/800.

@JoshuaHufford, what @chief21 said. The only way to know for sure what frequencies the antennas work at, without a manufacturer and model number of the antennas, is to use an antenna analyzer. If you’re interested in buying one, a NanoVNA can be purchased from Amazon for just under $100 regular price but has a Black Friday sale price of only $65. They are not that hard to use.

Thanks everyone, I've been wanting an analyzer for a while, this was the motivation so I just bought it. Was still $65 for cyber Monday.

I think you will like it a lot. As you get more familiar with it, you will discover the full potential of a NanoVNA. Search the YouTube videos on using it. Lots of helpful videos out there.
