Subject: Coax for HT DIY antenna Sun Jan 09, 2022 11:39 am
I have experimented with making feeder lines and antenna for a scanner with some success. Now I want to go further with my new HT on UHF. Finding it surprisingly hard to source decent coax in the UK. High Street retailers sell rubbish, eBay let me down with poor sheilded RG58, (even had stranded core, what's that about!) So where do you source decent RG58 or better? I have an eye on a Bazooka antenna design on YouTube that I want to attempt. Many thanks and 73 Rufus CT4392.

Have a look for "RG8X" coax. Not the best there is but good enough for me. I do have some 213 on my vhf/uhf antenna but i find it hard to work with.

Mini-8 (RG8X) is a good compromise. https://www.ebay.co.uk/itm/274895504222

Just buy it from a decent vendor, and use coax from a known manufacturer. Avoid eBay like the plague, and make sure CB shops are not just buying it from cheap Chinese disties then selling for a price you could get decent stuff for.
A HAM shop like Martin Lynch or Waters & Stanton would be a safe bet, but don't get sucked in to buying more than you need as it's just for a radiating element! Good, known brand, RG58 is fine for a Bazooka, but for UHF feedline, I start at LMR400 if I have any distance to cover.
Good coax is surprisingly cheap when you don't need much of it.
