Before I order any coax, I would be grateful if I could sound out on this reflector. I was hoping to get some RG174 coax at yesterday’s rally at Osset. I found the rally very disappointing. I took my CW test at the Wakefield rally in 1999, which was held at Thornes Park Stadium, it seems that this rally has gone down hill since then, certainly since moving to the new venue. There seemed to be only 2 vendors selling new stuff and neither of them had any RG174.
I want to feed my dipole with RG174. The dipole will be supported by a fishing pole and the weight of RG58 makes the pole bend too much. I intend to use 80m and 40m mainly, so the loss in the thinner coax is acceptable.
Can anyone suggest a suitable source of RG174? I intend to buy about 15 metres. The only place I’ve ever bought coax before was from Robin Sykes trading as SYCOM. Maplin don’t sell RG174 over the counter, only from the internet, and last time I looked it was 99p/metre!
I intend to use a Balun to feed the dipole (i want to do it correctly!) can anyone please suggest a suitable one? I’ve looked at some commercial baluns and they seem really heavy. Weatherproofing seems to be the bit that adds the weight. I’m not keen on ‘wind the coax up’ choke baluns as these will just add too much weight at the top of the fishing pole and I’m not convinced that they work properly unless they are wound to the correct diameter etc. Can anyone suggest a solution? I’m thinking I’ve seen a design using a ferrite ring and some windings somewhere. I was nearly serious about dissecting a commercial balun to strip the unneccessary weight, but I thought the cost (around £30) was too much.
73 and thanks in advance.
