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 its 3mm diameter. It's the same size as RG174.
Making a general-purpose HF Balun? Order 1m of this and wind 8-12 turns onto an FT140-43 or FT240-31. We also stock a ready-made 100w Choke/Balun.
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.
