coaxial cable

[Electric_Andy]

TLDR: Can anyone link me to a reputable supplier of some good quality (indoor) coaxial cable - presumably CT100 if that is the best option?

Background: My aerial (in the loft) looks like the old style. The cable has been run through the ceiling and down the staircase, but has been nailed to the wall (nails have penetrated the cable multiple times). I can't get a signal on some channels sometimes. So rather than get a new aerial or a booster etc, I thought I'd try new caoxial cable first and see if this rectifies. Does this sound sensible? I don't mind paying more for a better shielded cable, there seem to be a lot of cheapy cables pretending to be high quality.

p.s. I don't watch much TV, but when I do I typically don't get a good signal on the channel I have chosen!

75ohm I presume? Try Radio world or ML&S websites.

Sorry I don't know what ohms I require. I've been googling all day but it all seems to be akin to the bi-wiring speakers argument. Thanks for the sites I will check them out

Is it for a tv antenna or satellite dish? If so, will almost certainly be 75ohm.

This would do nicely...

You'll need the correct connector for the tv end and a pack of cable clips to keep it tidy.

yep 75 ohm is what you're after as Drago says, shame Maplins doesn't exist any more - I'd have gone there...

 

[Electric_Andy]

thanks. The chaps at Radioworld have suggested a 50ohm cable. i don't know what the difference is, or how to find out which ohmage I need?!

 

[Electric_Andy]

this is what they have suggested https://www.radioworld.co.uk/hq-10m_10m_rg-213_patch_lead

but I'd have to strip off one end, as my aerial looks old and has bare screw connectors?

 

[Electric_Andy]

Sorry it's for TV only, not satelite

Have you thought about an indoor aerial? We have one of these connected to the upstairs telly,and it picks up all the Freeview channels. https://www.amazon.co.uk/gp/aw/d/B01MAXT66E/ref=oh_aui_i_sh_in_o0_img?ie=UTF8&psc=1

In all honsesty 50ohm would likely be fine - no real issues with antenna matching to the transmitter on a tv receiver. RG213 is a reasonable,workmanlike quality, fairly well shielded. You'll need a bare end to screw to the antenna terminals, and the other end you'll need a...

50 ohm will go round tight corners better than 50 ohm.

 

[Electric_Andy]

Now I'm even more confused. I asked Radioworld if 50ohms is more suitable than 75ohm, and they replied (in caps) "YES YOU CANNOT USE 75OHMS WITH THIS"

 

[Electric_Andy]

ok thanks. The Radioworld chat doesn't seem to understand what I want, I shall go with your suggestions

 

[Drago]

Sounds like you got the work experience boy. Shame, cost they're normally fairly good. Thinks the sort of thing that Maplins were ideal for before they went breasts skyward.

75ohm is the correct spec, but in actual practice 50 should be fine unless you're running a mahoosive length.

They will have run out of 75 Ohm & have a load of old 50 Ohm sat on the shelf

Last time I needed some I went to Screwfix, seems to be good enough quality and competitive pricing, easily available through their stores.
