Co-axial cable - RG174A/U (with various fitted connector options)
Miniature 50 Ohm coaxial cable.
We also have pre-made 0.8m patch cables, just search Patch. The pre-made cables are cheaper than these custom-made cables, since we get them made in bulk.
Recommended maximum power: 125 Watts (HF bands).
If you would like a length that is not a multiple of 1 metre, please round to the nearest metre when adding this item to the cart, and leave a note in the "Order Comments" box during checkout about the actual length that you require. For most custom coaxial cables, we use a wire length counter to measure them out before fitting connectors, which has a resolution of 1 centimetre and is normally accurate to within around 1 or 2 percent.
For cable lengths longer than 10m, please see here.
Various connectors can be 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!
