50 metres of RTK400 Coax - Similar to WEB400, LMR400 and RG213

RTK400 50 ohm coaxial cable for HF/VHF/UHF and microwave 2.8 & 5.8Ghz frequencies.

Designed for very low losses on transmitters and receivers. Direct replacement for RG8, RG213, etc. This is a very high spec cable with a solid copper conductor.

Perfect for Ham Radio transceivers, it has a much lower loss than RG213. Can be used by ISP to ensure maximum power delivery. Ideal fro use on SCADA radio systems.

Can me sold in any lengths up to 250 metres. Please contact us if you need longer or shorter lengths.

Full waterproof. For use with PL259, SMA and N type connectors, plus others

This cable is very similar to WEB400 & LMR400. Power handling capabilities on a 30 metre cable length at 28Mhz is in excess of 2.5KW.

This is a very high quality cable with very low losses for the most demanding environments and can carry very high power. It is used by many of the telcos for their backhauls in very remote mountainous locations. A favourite of Ham Radio Operators in Ireland and across the World.
