Product Overview
Pasternack PE4215 is a straight SMA male (plug) connector with crimp/solder attachment for 50-ohm coaxial cables of 0.195-inch outer diameter - including RG58, RG303, RG141, PE-C195, PE-P195, and LMR-195. The center pin solders onto the cable center conductor; the outer ferrule crimps over the braid. PTFE dielectric and gold-plated brass center contact deliver reliable performance to 12.4 GHz with a maximum VSWR of 1.5:1.

Applications
- RF test bench builds - strips RG58 or LMR-195 to length, solders the center pin, crimps the ferrule, and terminates a custom interconnect between signal generators and DUT.
- Field repair of wireless infrastructure - cuts away a damaged connector on an LMR-195 antenna feed line, terminates a fresh PE4215, and torques onto the bulkhead SMA jack to restore the link.
- Ham radio antenna cabling - terminates a handmade RG58 dipole feed line with a reliable SMA male for handheld transceivers and HF upconverters.
- SDR setups - builds a low-loss pigtail from bulk LMR-195 to connect an RTL-SDR dongle to a filtered antenna or LNA without the loss penalty of off-the-shelf consumer cables.
- FPV and RC telemetry - terminates custom-length RG58 runs on video transmitter boards or 900 MHz telemetry radios where standard pigtail lengths do not fit the airframe.
Frequently Asked Questions
Which cables does this connector fit?
PE4215 is designed for 50-ohm coaxial cables with a 0.195-inch outer diameter: RG58, RG303, RG141, PE-C195, PE-P195, and LMR-195. It is not compatible with RG174, RG316, RG213, or 75-ohm cables such as RG59 or RG6.
Is this standard SMA or Reverse Polarity (RP-SMA)?
This is standard SMA - male plug with a center pin. It is not RP-SMA. Consumer Wi-Fi routers and many off-the-shelf wireless adapters use RP-SMA, which has a reversed pin configuration. Verify your equipment port before ordering.
What tools are required to install this connector?
Installation requires a coaxial cable stripping tool sized for RG58/LMR-195, a soldering iron for the center pin, and an RF crimp tool fitted with a hex die sized for the ferrule. Without all three tools, this connector cannot be properly installed.
Will this connector work above 12.4 GHz?
The PE4215 is rated to 12.4 GHz. It is not suitable for millimeter-wave applications requiring 18 GHz, 26.5 GHz, or higher-rated connectors.
What is the mating interface on the equipment side?
This is an SMA male plug. It mates with a standard SMA female (jack) port. Recommended installation torque is 3 to 5 in-lbs on the threaded coupling nut.
Pasternack has been making these connectors for working RF benches and field installs for decades - the gold pin and PTFE dielectric are still bright and clean on this one. Strip, solder, crimp, and it is ready to carry signal.
