Hi, what is the very best coax we could buy for our hobby please, I have been freebanding on CB and made my own antenna and wanted to get the best coax for it, I ended up with westflex £50 for 20mtr,

I did find this calculator loss link for ham radio, surely coax loss will apply for tv cable ? what is the best cable we could buy please

Err... Depends. Webro 125 type cable is the most expensive but only if you really need it.

Or there's fibre.

In most cases, a Webro type 100 is more than fine for modest distances.

Anything under 30m just use some wf100.

Wf125 is recommended for cable runs over 40 metres.

I use twin wf100 and its fine but my cable run is only about 14 metres anyway.

If you use wf125 then don't connect it direct to receiver as its heavy cable and could damage the f connection on receiver and they also use different size connectors.

Thanks lads, this is the difference between good cable and not so good with Ham radio, and I just thought they may be a good thick better coax for tv, we talk about tweaking this tweaking that we must not forget the importance of coax quality ?.

I've used WF 100 for everything that I've done, nothing over 25m. I also use cablecon compression f connectors with a waterproof o ring insert

WF100 is a good quality cable and excellent for both IF, satellite and RF, TV/FM. The original CT100 was a very good quality with lots of copper in it and performed very well, but has not been made for years and in fact had a hollow dialectric, as opposed to most modern cables, which have foam and are much more resistant to folding damage. Beware any modern cable labelled as CT100, as it will often be a very poor Chinese made cable, often not complying with the RG6 specification, for example, the core being less than 1mm.

Is it for the CB or the TV?

TV and satellite co-ax has an impedance or 75 ohms. If CB radios are anything like amateur radio rigs then they will need 50 ohm cable. Frankly, at 27MHz signal loss is not really something to worry about but if you wanted to then something like Westflex 103 would be good.

EDIT

Ha! I see that Martin has already mentioned Westflex 103 while I was composing my reply.

Another WF100 user here. I just buy it on 100m rolls and keep it in stock for when it's needed. I don't know where it all goes, but I'm always running out...

Many thanks, I am quite sure I am using both mentioned coax on 1 run, I just wondered if anything better was out there, once I start work on my next project I just want to give it the best

The old Raydex CT100 was a high grade cable. I often use a Triax TX100 type (MPN: 370752), a little tougher than WF100 with losses around the same.

You can get 75ohm coax cable from Webro with even better specifications than wf125 but honestly for almost every domestic installation, overkill would be putting it mildly. The only time you might even consider going above wf125 for a satellite install would be if you couldn't locate the dish less than 75 metres from the receiver, and even then a sloping amplifier placed somewhere along the feed might do in many such situations. Such better spec cable would be used in the likes of trunking either in large buildings like blocks of flats or business estates to keep losses minimised on very long runs even with amplifiers in place, or where long underground runs are needed and fibre for whatever reason isn't an option.

IIRC Webro's highest spec 75ohm coax cable is wf340. It's not cheap either.

The run from my 1.8 is about 35m down the garden and the best solution for me was to use CT125 RBS. It's cheap, has good spec and can take direct burial, it's a pig to route indoors but fortunately that isn't an issue here. There was an obvious improvement on marginal signals when I switched from the previously installed RG6 .

At which point you might be considering one of Heliax's offerings.

And even more "not cheap either"!

A little less analogue, and a lot more crap.

For quality, I always put a bit of CT233 in risers when I was mucking about with SMATV systems, and CT167 for the secondary taps.

I think if i had to cover more than 50m i'd just go for fibre Optic. You can buy pre-terminated lengths fairly cheaply these days.
