EZ-400-TF-RP Reverse Polarity TNC-Female Connector for LMR-400 Coaxial Cable
EZ-400-TF-RP is a Reverse Polarity TNC female (jack) connector from Times Microwave Systems specifically, for LMR-400 coaxial cable. Features an “EZ-style” solderless, crimp Connector for fast field installation, providing 50 Ohm impedance and excellent VSWR up to 3 GHz. Crucially, this female body contains a male center pin.
Key Product
The EZ-400-TF-RP is engineered to set the new “gold standard” for easy and consistent termination of LMR-400 type coaxial cables. In effect, it eliminates the need for soldering, consequently drastically reducing installation time and potential errors in the field.
- The RP-TNC Female connector (Jack) houses a male center pin inside its female body, making it suitable for specialized RP-TNC male connections often found in Wi-Fi and WLAN systems.
- Solder-Free EZ-Style Design: Employs spring finger contacts that securely clasp the cable’s center conductor, creating a reliable, low-resistance DC connection without soldering.
- Superior Signal Performance: Provides excellent broadband VSWR performance and a low insertion loss for reliable signal integrity.
