RG-58 £10 per 50 meters.

Postby m0lsx » Fri Mar 16, 2018 6:35 pm

For those new to the hobby RG-58 is NOT suitable for scanner use.


But if anyone is wanting a drum of RG-58 coax. Moonraker is selling 50 meters for £10 & 100 meters for £20.

It has 50 Ω nominal impedance with known losses 2dB/10m to 100MHz.

I do occasionally run an RF amp when necessary but for general listening on 2m/70cm and occasionally air band its great. In fact I use a 2 metre run to a cellular colinear for ADS B as well as my antenna for 4m for transmit. No problems and that is 15 long.

I have no problems whatsoever on a 10m run all the way to 470MHz.

That really depends upon how long the coax that you want is & what you listen too.
In general RG-213 is considered to be the minimum quality for scanning. But something like good quality RG-8X is also acceptable. However on longer runs Say 35 to 40 meters & up, I would personally use something better than RG-213. Although I do in general use better coax on my VHF/UHF antennas as standard even on shorter runs anyhow. But only because I choose to do so, not because I need to do it.
The thing to realise is that anything that starts with the letters RG was originally a military specification. But that it has not been Mil Spec for years & in general, now it is simply giving you a rough idea of what you are buying. So buy the best coax you can, from the most reliable source that you can. As not all coaxes are equal, even if they have the same title, be that RG-58, RG-213, RG-8 etc etc.
So treat claims of Mil Spec coax with suspicion, as if it is RG coax, then it was Mil Spec to start with. But many years ago & Mil Spec is now a sales pitch, not a statement of fact. Also look at the coax, you want a good outer braid, as that is what keeps your signal in. That is why good quality coax is not cheap. As it contains a lot of copper.
