RG316 coaxial cable for use with high-power (400w) baluns and hook-up cables in microwave projects. PTFE insulation which does not melt when soldered - and capable of high-power use despite it's 3mm diameter. It's the same size as RG174.
This is not a "long run" feeder coax - it's more suited for baluns and short internal hookups.
Sold by the metre in 1 continuous length, so order 1 for a 1m length, 3 for a 3m length etc. See also RG142 for a QRO cable.
