Product Description
SO-239 - UHF-Female Panel Mount Coaxial Connector
The G511 is a UHF-Female (SO-239) 4-hole panel style connector and it has a large solder pot that will accommodate large center conductors like those found on LMR400.
The G511 is manufactured of a brass alloy body and silver plated for superior performance and value. It has a PTFE (Teflon) dielectric and a gold plated brass center pin. The UHF female interface has 16 machined points to ensure a proper seating of mating UHF male (PL-259) connectors.
The Delrin is a rigid, high-strength thermoplastic best for mechanical parts like gears and bearings, while Teflon (PTFE) is a low-friction, non-stick polymer ideal for applications needing chemical resistance or minimal slide friction. Delrin has a temperature resistance (up to 200°C) and higher mechanical strength, toughness, and wear resistance, while Teflon offers superior chemical inertness, higher temperature resistance (up to 260°C), and extremely low friction. The choice depends on the application's primary requirements: mechanical strength for Delrin and non-stick/low-friction performance for Teflon.
Teflon is a registered trademark, originally of DuPont, but now owned by The Chemours Company (a DuPont spinoff), which licenses the brand for its fluoropolymer materials like PTFE.

Five Stars
I just got started in RTL-SDR (Software Defined Radio) and I saw an article where one could make (DIY) Ground Plane Antenna with radials using the SO-239 as a base. I purchased three of these connectors and I'm making my own Antennas... tuned to specific Radio Frequency. There SO-239's are a great help, they're inexpensive and just what I was wanting!

Works Well
I would buy again.
-
Well Made
Well constructed and the insulator does not melt when soldering.
-
Perfect!
Excellent Quality and Fit. I ordered SO-239 panel connectors which worked perfect.
-
Good Product
Its smaller than I thought but makes up for it in quality.
-
Excellent
Excellent solder adhesion .

Exceeded Expectations
Used these to make a quarter wave ground plane antenna for our club to use for demo at county fair. Well made. Got several from another vendor and they were small and poorly constructed compared to the ones I got from American Radio Supply. Everyone was impressed with the quality and kept asking me where I got them. A friend got one off me for a radio he is building. Quick shipping and well packaged. Exceeded my expectations.
