# UHF, PL-259, SO-239. What is the difference?

[Michael Crudele](https://blog.arcantenna.com/blog/author/michael-crudele) ·  Mar 31, 2026, 1:54:16 PM · 3 min read · [PL259](https://blog.arcantenna.com/blog/tag/pl259) [SO239](https://blog.arcantenna.com/blog/tag/so239) [UHF](https://blog.arcantenna.com/blog/tag/uhf)

![UHF, PL-259, SO-239. What is the difference?](https://cdn.shopify.com/s/files/1/0345/4055/2323/files/PL-259_Male_and_SO-239_Female_480x480.jpg?v=1600363703)

I get many inquiries each month from customers looking for [NMO cable kits](https://www.arcantenna.com/m2m-antenna-hardware/m2m-antenna-mounts-brackets/nmo-motorola-style-mounts.html?connector_1=328&dir=asc&limit=60&order=position) and mounts for radios with UHF connectors. The problem is that there is often confusion concerning the terminology used to describe UHF connectors. The most common questions that I get on this topic are:

- Is [PL-259](https://www.arcantenna.com/collections/connectors#?Collections=CONNECTORS&search_return=all&Metaconnector1=UHF+Male%2F+PL-259%2F+UHF+Plug) the same as UHF Male?
- Is SO-239 the same as UHF Female?

So, I thought that our blog would be a good place to clear up any confusion once and for all!

Here are the facts...

- UHF-Male (or UHF Plug) is THE SAME as PL-259.
- UHF-Female (or UHF-Jack) is THE SAME as SO-239.

The above connectors are used in applications like amateur / HAM radio, CB / Citizens Band radio, Marine radio & VHF radio. Typically, the SO-239 (UHF Female/UHF Jack) is installed ON THE RADIO, and the PL-259 (UHF Male/UHF Plug) is installed ON THE CABLE. The two "mate" and are collectively known as a UHF Connection.

**(Left) UHF Female SO-239 vs. (Right) UHF Male PL-259**
