Any Pronto's or Q-Flags about? The clansman kit had two CJD's - or 'baluns', as civvies refer to them: 1. a "small" one with the 320 which has the typical BNC co-ax connector, 2. a larger one that - iirc- came with the 321 ancils bag, and had a much larger BNC co-ax connector, much like a PL259 in size. Can anyone tell me what type of balun either was a choke/current, or transformer/voltage balun, and what ratio e.g 4:1, 1:1, 9:1? I'm presuming - no longer having course notes - that both 320 and 321 expected a 50 OHm load on the co-axial output? The why? I've got a 320, currently running off a dipole. Just acquired a Kenwood TS530, AT-230 ATU (and possibly a Versa II), and need to construct an antenna or two. Neither the Kenwood nor the AT-230 have a balanced output, so I cant use ladder-line without a 4:1 balun. I can feed a dipole of course, but will need a balun... (or just run it as co-ax end-fed multiband) The "small" balun is in use on the 320, I have a "large" clansman balun, but don't know if this will be suitable. Anyone know?
