This special low-loss SMA male to N female extension cable is 240 grade (LMR-240* equivalent loss) low loss shielded for 6, 10, and 15 foot length options, and 400 grade for 25 and 50 foot options.
240 and 400 refer to shielding thickness. The thicker shielding means lower dB loss. 240 grade is .24 inches thick, while .400 is ~.40 inches thick. 400 has less loss. For length up to 15 foot, 240 is more than adequate, but for 25 or 50 foot length, the 400 is recommended.
The cable can be used to put an extension between an SMA antenna connector on a LoRa device or Meshtastic radio and an N-male antenna.
Commonly used for Meshtastic and LoRa devices
This cable is compatible with N-male outdoor antennas.

As the cable in between the antenna and adapter gets longer, you will experience cable loss, which is a drop in the signal gain of the antenna. With low-quality unshielded extension cables, the huge drop in gain will mean a much lesser range. Our special low loss cable limits the cable loss factor and preserves the high gain of your antenna.
We do recommend RokTape to seal all outdoor connection points.
Compare gain loss of this cable at 6ft example length:
915 MHz application: – 0.4 dB (LoRa device)
Compare this to a cheaper RG-58 shielded cable of the same length- the gain loss would be -0.9 dB for 915 MHz. Twice as much loss with inferior cable!
Additional Features:
– Impedance: 50 OHM
– Frequency: all bands from 0-6 GHz, including 868-915 MHz LoRa
