Folks, as I'm a noob when it comes to RF cable,  this should be decent right ? :-//

Just bought 50 meters of RG8 equivalent, coaxial for my GPSDO antenna, Leoni brand.

Well, I'm also get irritated by people who always suggesting a 1st time scope buyer that they already admitted they're practically a beginner, to buy an used analog scope, even already stated they can afford the budget for a "new" entry DSO.

Well the point is that if you can get a working CRO for a few quids, then thats the way to learn surely and then if they ultimately fuck it up, its just a few quid down the drain rather a few hundred. Better to make your noob mistakes on a cheap piece of equipment rather than making those mistakes become expensive ones. Once your relatively with an old CRO, upgrade to a DSO entry level one or maybe slightly better when you have a better appreciation of what they are and how to use them correctly.

Should be fine. RG8 is usually specified up to about 2.2GHz. It will have loss and this is significant at 1.5GHz so keep the run as short as possible. Sod terminating RG8 like that on anything other than N/PL259 though. I’d probably have used RG174 and lost a few dB to be lazy :)

I’d go as far to say that as a beginner you are doing yourself an ill if you don’t have something known in hand. Known usually means new.

Only if you know it works. Most of the scopes I’ve sold so far have gone to beginners who want something that works correctly and has some after care. It’s quite difficult to find a trustworthy analogue scope.
