What Is RG316 Coax?

RG316 coaxial cable is a low-loss, high-frequency cable with a characteristic impedance of 50 ohms. It's primarily intended for radio and data communications. This robust cable is flexible, suitable for burial, and appropriate for use over a wide temperature range.

RG316 Cable Construction

RG316 is a coaxial cable with a stranded silver-covered copper-clad steel conductor made with seven strands of 0.0067-inch diameter wire. The conductor has a solid polytetrafluoroethylene (PTFE) dielectric insulation that allows a wide range of operating temperatures from 200ºC down to -55ºC. A shield made from silver-coated copper braid covers the dielectric insulation, and there's a transparent protective jacket made from fluorinated ethylene propylene (FEP) Type IX as per MIL-DTL-17 specifications.

The coaxial cable's diameter conduction allows for relatively high-power transmission capabilities, depending upon the operating frequency. At 10 Hz, the cable can transmit 1,869 watts while at 3 GHz, the maximum power is 93 watts. The cable's maximum operating voltage is 1,200 volts.

RG316 Coaxial Cable Impedance

The characteristic impedance of RG316 coaxial cable is 50 ohms. Note, this is not the electrical resistance of the cable but rather a complex term related to the effective electrical impedance of the line to a radio frequency electrical wave taking inductance and capacitance into account. The important aspect is that the impedance of the cable must match that of the transmitting and receiving device to avoid reflections that cause interference. The characteristic impedance of coaxial cables differs according to the coaxial cable classification type, with 50- and 75-ohm coax being the most common.

Signal attenuation, measured in decibels (dB), depends on the frequency of the signal. At low frequencies, it's primarily determined by the electric resistance of the cable, whereas at high frequencies, by the cable capacitance. At 10 Hz, the attenuation of RG316 coax is 2.5 dB per foot while at 3 GHz it's 47 dB per foot.

RG316 Coaxial Cable Military Specification MIL-DTL-17
