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.

Very high-quality cable. I use it for 1090 MHz and it's working great!

Works great hooked up to the ADSB Antenna on the roof .1090 MHz Filter and Flight Aware USB receiver to the Raspberry Pi 3 . Antenna is about 25feet off the ground and receiving ADSB aircraft signals 150 miles out depending on terrain .

I had a FlightAware ADS-B 1090 mhz antenna+cable kit mounted outside for 3 years. The cable was thin and the shielding was thin aluminum foil. Rainwater leaked into the antenna connection and dissolved the shielding, creating resistance. After about a year, signal quality was reduced by half. I repaired the connection, but reception was still poor. I recently added a 978 mhz UAT dongle/antenna kit from Radarbox (free from them) which had a better cable and provided better reception for the 978 dongle. Then, it clicked > my cable was the problem! I researched antenna cable for ADS-B and settled on this one. It is thick, sturdy and well insulated from rainwater intrusion. Since installing it, aircraft distance reception has increased from 75 miles to almost 200 miles. The only con I have is it's thickness but I'll accept that for the great signal throughput it provides.
