SMA / N Coax Extension Cable


Low Signal Loss  Copper Core and Gold Plated Pins  Pro Grade Quality  Indoor Outdoor Use
Ultra-low-loss 50 Ohm coax cable for maximum RF reception and transmission at common wireless frequencies. Significantly outperforms “RG” coax cables. Solid copper core and gold-plated signal pins provide top-quality, high-performance conductivity. Commercial-grade components ensure maximum toughness and durability. Cable is assembled, inspected and 100% tested by in our ISO-9001 certified facility. Polyethylene jacket withstands abrasions and provides excellent moisture resistance for outdoor use (not rated for direct burial or plenum applications).


Proxicast recommends 0.195 inch diameter coax for assemblies up to 10 ft, 0.240 inch diameter up to 25 ft and 0.400 inch diameter up to 75 ft. It is acceptable to use a thick cable for the long portion of a cable run and a short thin cable to connect to equipment or antennas, but minimize the total cable length and number of connectors. Cable runs longer than 50 ft will generally require an in-line amplifier.

To ensure that you are selecting the correct cable, please refer to the Support tab for information regarding RF Connectors and Signal Attenuation.

Note: All outdoor coax connections must be weather-proofed to minimize damage caused by moisture in the connectors or cabling.  Use our Self-Bonding silicone tape (ANT-900-002) for fast and easy connection sealing.

Pro Tips

For Best Results

  • Use the shortest possible cable
  • Do not cut or splice the cable
  • Observe the minimum bend radius of the cable at all times
  • Minimize the number of connectors used
  • Fully tighten coax connectors
  • Weatherseal all outdoor connections with silicone tape (ANT-900-002)
