What is RG316 Cable?

RG316 coax cable can be used in direct burial, radio frequency and telecommunications applications. Often used for the transmission of radio frequency signals, RG316 cable can also be used in wireless communication, broadcast and military equipment. RG316 coax may also be used for high frequency interconnections between PCB in telecommunications equipment. RG-316 cable is a good choice for applications like these which require good performance and stability in high temperature environments and superior phase stability, or for applications in demanding environments or with minimal installation space. RG316 is a high performance coaxial cable that is in accordance with MIL-DTL-17 specifications. The M17 part associated with coax RG316 is M17/113-RG316.

RG316 Loss | Attenuation Frequency:

This RG316 cable loss chart gives you common frequency and loss characteristics. RG316 attenuation, or loss, is lower than other options in this category due to the large sizeo of its conductor. For example, RG178 loss is nearly double RG316 attenuation. For additional information on the topic, read our RG178 vs RG316 blog post.

Power Handling by Frequency

The RG316, like the RG393 and many other Mil Spec coax cables, has excellent power handling capabilities due to the high thermal conductivity.

Frequency (MHz) Power (watts)
10 1869
30 1072
50 827
100 580
400 282
1000 173
