Strange Coax

Ive just been up into the loft and found a large run of coax but I’m not sure if it suitable. I would post an image but I don’t think this board allows you to .

To describe it there are no markings the usual black outer casing but thicker, it has a thin plastic braid over the copper braid with a plastic core and central wire bordered by five holes in a circle.

Any ideas if I can use this please

That sounds very much like coax for a satellite dish or cable tv possibly which will be 75 Ohm and not the required 50 Ohm.
I have always been advised to get the best coax my budget will allow and if you look into line loss you will see why.
Here is a handy calculator: https://www.qsl.net/co8tw/Coax_Calculator.htm

Thank you
That is a big help but also a disappointment as I wont be able to use the cable and there is a lot of it. I guess its got to go in the bin, a shame

You should keep it, it could be used on another project such as extending a router or television or satellite installation possibly, you never know when it may come in handy if you have room in the shed that is.

I have had satellite installed in several houses but never had coax in the loft.
You can host an image then show us what you have.
Load it onto imguru or a site like that then link it in a post on here.

Thank you all
I was ferreting up in the loft yesterday and came across this large run on coax .The radio is one in the garage and re set up with a painted green 1/2 wave pole and a pin inverted V wire antenna.

One question , can you make a 3 element beam wire antenna ?

Many thanks

Yes, you need a rigid structure to support the wire with people using anything from bamboo cane to PVC or fibreglass tubes. I had a 4 element aluminium Yagi up and I had to reinforce all the elements with something I picked up in the local hardware store as the wind sent them all directions and that was from one of the so-called quality brands too I seem to remember.
