FAQ’S:

1. Is this UHF female socket compatible with PL-259 male connectors for RF applications above 300 MHz?
While the UHF socket (SO-239) fits PL-259 connectors mechanically, it’s best suited for applications up to 300 MHz due to its non-constant impedance. For higher frequencies, consider precision RF connectors like N-Type.

2. Does the SO-239 connector have a true 50-ohm impedance, or is it only approximate?
This UHF female connector offers an approximate 50-ohm impedance, acceptable for most analog RF setups like ham radios and CB systems, but it’s not precision-rated for digital RF.

3. What’s the dielectric material used in the UHF female socket, and how does it affect performance?
It uses PTFE (Teflon), a high-grade insulator known for excellent thermal stability and minimal signal loss, making it ideal for reliable RF signal flow within the 0–300 MHz range.

4. Is this SO-239 connector suitable for high-power RF transmission in HF or VHF bands?
Yes, the SO-239 connector can handle moderate to high power levels in HF and lower VHF bands, provided proper ventilation and grounding are maintained in the system.

5. Can I directly solder this UHF female socket onto a PCB for custom RF circuits?
Absolutely. The rear solder-type pin design makes this UHF female connector PCB-mount friendly — perfect for radio enclosures, RF filters, or custom transceiver projects.
