    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.

    So far, it took 34 no. of days to arrive in my location (Butuan City, Philippines and the item is safe and intact except for minor bruises in only one portion of the coax. I have not tested it yet & i have to submit for another review later. Its quite good looking item.

    RG174A/U preterminated coax

    Posted by David on 12th Jul 2019

    This is an excellent product that works well. I bought the 10 m version with a BNC plug at each end, it's really convenient and even works well on six metres.

    Good quality coax

    Posted by Adrian Bayling on 20th Jun 2019

    Good braid density, nice flexible stranded inner conductor. I bought enough to feed a new linked dipole, and also to replace the RG58A/U on another. Happy customer.
