Co-axial cable - RG174A/U (with various fitted connector options)

Miniature 50 Ohm coaxial cable. Approximate lengths 3m (9ft 10"), 5m (16ft 5"), 10m (32ft 9"), 15m (49ft 2.5"), or 20m (65ft 7"). We can make cables to other lengths, just email us.

We also have pre-made 0.8m patch cables here: Patch Leads RG174. We have 20cm and 30cm pre-made 20cm & 30cm Patch Leads RG174 The pre-made cables are significantly cheaper than custom-made cables, but the choice of connectors is more restricted and we only stock them in short lengths.

Recommended maximum power: 125 Watts (HF bands).

Various connectors can be professionally fitted on one or both ends (great for antenna experimenters). Connector protected with adhesive lined heat-shrink sleeving for improved water resistance.

A top quality MIL-spec cable with a stranded inner. Perfect for feeding lightweight HF antennas!

    Posted by Martin Hanraads on 19th Jan 2024

    Bought a 10 metre cable with BNC plug and socket fitted. Arrived promptly, looks like good quality, nicely fitted plug and socket. Tried out on my portable dipole and works fine.

    I like these cables and have now purchased 4 or 5 from Sotabeams. They are light weight and ideal for SOTA / POTA Activation's. This is the only one that I have purchased to date with only one BNC connector on I normally buy double BNC ended cables. They work well both at home (Still in lock-down level 3) so looking forward to getting out to use them again. ZL1MX.

    Very good quality cable with well fitted bnc. Great to have SOTA provide this facility as my eyesight prevents me soldering now.
