FAQ

Q: What is the maximum frequency for RG393?
A: RG393 is rated for use up to 11 GHz, with excellent attenuation stability across the frequency range.

Q: What is the difference between RG393 and RG316?
A: RG393 is a larger diameter cable (9.9mm vs 2.8mm) designed for higher power handling and lower loss. It features a heavier 7×0.80mm conductor and can handle up to 2500V compared to RG316's 1200V.

Q: What connectors work with RG393?
A: RG393 accepts connectors designed for 0.390-inch diameter cable, including N-Type, TNC, SC, and HN types. Custom assemblies available.

Q: Can RG393 be used outdoors?
A: Yes, the FEP jacket is UV resistant and weatherproof with excellent resistance to fuels, chemicals, and oils.

Q: What is the minimum order quantity?
A: We sell by the meter/foot with no minimum order quantity. Custom lengths available.
