Inside your shack use RG58 with BNC connectors, as long as your frequency is below 50 MHz, power is below 100W and length is around 1-2 meters. At higher powers use RG213 with suitable connectors e.g. SO 239. That's okay up to 144 MHz if connectors are good quality and lengths are not to long. At higher frequencies use some form of foam- or air-coaxial low loss cable and good quality N-connectors.
This is a great response. Thank you jopie.
Looking at element14, digikey & RS it's not that straight forward to identify what's going on with what coax. Doesn't seem to be for me anyway.
What I'm seeing is that, weighing up cost, availability, and pliability, RG58 is a good compromise for short or temporary installations. It appears that I'm better to get set up with a bunch of that and worry about how to deal with higher frequencies and longer runs on a case by case basis as they come up.
In doing further research I see LMR-400, LMR-600 and Heliax. These don't appear to be available from the usual suspects. Should I be looking at specialist suppliers for these things?
Still no mention of length or fitting styles , mention of 1KW so your still going to use PL259's aye Ha Ha Ha , I'll get out of here , bye .
Why? PL259s are shit at UHF.
The Wikipedia article is quite a useful quick comparison of the characteristics of different coax types:
https://en.wikipedia.org/wiki/Coaxial_cable
There's a bunch of information on the internet. There are also a thousand kinds of coax; different standards, sort-of-standards, names, pseudonyms, and trademarks. This is a too much information for a noob.
At the very least you need to state what problem you are trying to solve.
OK:
I was just going to buy a roll of RG58 and make do with cables as short as possible. Then I thought, perhaps you guys have a better idea. Since I have nothing right now, I can start out with whatever is the most suitable. In the short term I'll just be dicking around with HF, but if it's not too much more now, maybe I can save money by not duplicating all my cables for UHF/microwave if I get interested in that later.
1kW and coax (or not) implies it isn't suitable for amateurs to play around.
OK
What research have you done? There's no point in asking us to duplicate your existing research
I'm not asking anyone to do any research. I thought that was clear from the tone of my original post. If you've already done the research, and you're prepared to burn a minute or two dropping me a line of insight, that'd be great.
and if you haven't sone any research then it is impolite to ask us! FFI, see https://entertaininghacks.wordpress.com/library-2/good-questions-pique-our-interest-and-dont-waste-our-time-2/
I don't know if
I'm having a bad day, or you are. My initial reaction to this is a big Fuck You. I re-read my original post, and the tone seems fine to me: Light, inviting casual comment. I'm no word-smith though.
Anyway, mate. I've spent days looking at specs, suppliers, charts and graphs. I've decided what I'm doing, and I thought I'd raise it here in case someone else's experience would save me $500 replacing cables in the long term.
