JEFA Tech 50 Feet SMA Male to N Male - Premium 400 Flex Low Loss Cable, for External Antennas with N Female Connectors, 4G LTE, 5G Modems/Routers, Ham Radio, ADS-B, Meshtastic CA-400F-NM-SMA-50

This cable directly connects any 4G/LTE/5G modem/router with SMA Female cell connector to any external antenna that has an N Female connector. CNot all cable is made the same! Our cable is industry leading with the lowest signal loss available. Signal loss is approximately 5db per 100ft of cable ( 1.6 dB per 10m). Lower numbers are better. To determine your break-even point for cable length divide your antenna gain by 0.05. Example 5dBi antenna = 5 / 0.05 = 100ft. This means with a 100ft cable, you are now at zero net gain for your 5dB gain antenna.

In situations where the signal outside is good (3-5 bars), you can typically increase the cable length past the break even without a problem. If the signal outside is poor (1 bar), it is recommended to keep the cable length as short as possible. Need help?
