Review: Very stout with great build quality - This cable appears to be very well built and is quite stout. If you are looking for a no-compromise cable to connect between an SMA-female device and an N-female antenna (or vice-versa) then you will be happy with this purchase. Not being familiar with KMR400 but having familiarity with the higher-spec LMR400, I did some brief research and concluded that this will definitely suit my needs considering the length of the cable (3') and the frequency of interest (915MHz). When I bring my Meshtastic node in for servicing, I will test the insertion loss of this cable to give a sense of what its characteristics are in real life. I do not anticipate a measurable loss considering the ratio between cable length and the measurement error of my Rigol DSA815-TG spectrum analyzer.
Review: Good Quality - Nice upgrade for the cable that came with the antenna I purchased.

## Features

- Heavy Duty Connector: This kmr 400 cable is with SMA Male to N Male adapter and the heavy duty connector is made of solid copper. and it is waterproof that they could be used in the outdoor antenna.

- Prevent Coming Off: Our n to sma patch cable adopt the clamp connector not the crimp type connector so the connector will not easy come off from the cable and all the connections are solid and professionally attached.We use the black heat shrink tube and lined adhesive by heat shrinking to connect the adapter and the coaxial cable . And the length is up to 2.2 in that is longer than others which would prevent the connector coming off.
