KMR400 SMA to N Cable 25ft, N-Male to SMA-Male Connector Low Loss Extension Cable 50 Ohm SMA Cable for 3G/4G/5G/LTE/ADS-B/Ham/GPS/WiFi/RF Radio to Antenna Use (Not for TV)

Large, thick, very well made cable. The quality is apparent. You will notice that it's fairly stiff from all the shielding. I have no connection or signal issues. Would recommend.

Works 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 have modified my T-Mobile 5G home internet router to accept SMA antenna connectors for an exterior antenna. I had previously used some longer and inexpensive RG-58 cables with my installation and had some issues pulling the higher frequencies for 5G. I relocated the antenna and modem to utilize better quality and shorter cables. My signal levels have not dramatically increased, however my connections are much more stable and I am more frequently running on the higher frequencies for 5G! That's a win in my book. I originally bought 3 foot cables and could just barely make them work, but I wanted a little more slack and returned them for 6 foot cables.The cables that I received had nicely terminated cabling and I have no complaints.I plan to purchase more of these cables for installations in the future for any frequencies above VHF/UHF ham frequencies. Going to be installing some Meshtastic antennas soon, and plan to use some of this cabling.

The cable is stiff, but I knew it would be to keep any loss to a minimum, and shield from any rf noise. The cable works as designed, and while stiff, gets the job done.

Used this to connect my phone signal antenna to my inside signal booster.

I was using a 25ft KMR240 for my ADS-B (978/1090 MHz) plane tracking, but due to some re-configuring, I needed more length. The signal loss in KMR240 with lengths over 25ft was more then I was willing to accept. I bought this KMR400 in a 35ft length to replace the 25ft KMR240. The KMR400 is much bulkier, heavier and more difficult to bend compared to the KMR240. However, the signal loss around 1000 MHz was much lower then the KMR240, so despite adding length to my cable run, I was able to lower my cable losses (attenuation). This particular cable is well made and I expect it to last for many years.

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.
