This yellow velcro strip is ideal for keeping your cables tidy as well as 101 other uses including "portable" Amateur Radio operating - Keep your coax secure against a mast/pole or just keep the wires neat and tidy during transport. It's 10mm wide and sold by the metre, so if you order 3 you'll get a 3m length (max single length is 5m). We also sell a 20mm wide version.
It's amazing what you find in boxes these days - We found a full roll so have this 10mm wide strip available while stocks last!
We find that 15-20cm is a good length for securing coax/feeder to a fishing-pole - and, like many of our products, we use them ourselves when out /P.
