Interface Cable - RPSMA Female to RPSMA Male (25cm)

This is a basic RPSMA (Reverse Polarity Sub-Miniature A) male to female connector cable. Each cable is 25cm (9.8") long and has a 50Ω impedance that can handle frequencies up to 17 GHz. The RPSMA connectors at each end are small enough for most consumer WiFi and other RF applications and they use a threaded housing to create strong mechanical connections.

These work well for mounting an antenna to the outside of an enclosure, while keeping the electronics neatly inside.

Note: If you are looking for an SMA interface cable, it can be found here.

  • I believe this (RPSMA) is the type of connector/cable that wifi routers usually use. The SMA one us usually used in cellular and GPS antennas. Don't get them mixed up or they won't fit!

    (For anyone not educated on the difference between the two, look at the middle pin on the male connector. If the pin is male, It's a RPSMA. If the pin is female, it's a SMA)

    Do these come with the washers and nut for panel mounting?

    • They don't, according to the pictures, let me double-check to make sure. sometimes we get the hardware separately and include it with the product, and it doesn't end up in the pictures.

        The RPSMA cable listed here shows it without but the SMA cable linked above shows it with the hardware.

        • They DO include hardware, we just ended up shooting one without hardware for some unknown reason. I checked and they all have nuts and washers. We'll update the picture shortly.
