TV coax cable

[DIYspanner]

Having recently installed a new 12db gain aerial in the loft, I get around 85% signal and 100% quality yet the TV still gets pixelation.

The cable in the loft and TV socket in the g floor room were already installed when I move in early 2022 so presumably installed when the house was built in 2003/04.
The cable is marked 'pro-power 75ohm low loss coax' but it does not have a shielding foil under the outer metal braiding.

Is the cable acceptable for Freeview?

To be fair, it's not the best - it has limited screening ability, and so might well pick up all sorts of RF noise, such as thermostat clicks, anything switching. Modern coax would be much better, such as CT100, but there is more modern than that FP100 I think.

It might be cheaper bought by the full coil, than by the metre.

You have low loss coax with pretty poor braided screening. ProPower seem to be a CPC/Farnell own label brand? Their website is not playing ball so I can't tell if all copper or nastier stuff.

It'll likely work OK unless running near other things that produce interference, when the lack of screening will become a big issue.

CT 100 was dreadful stuff... Air spaced. No longer made. Other brands use the CT100 name for some really dreadful coax. Avoid!

Webro WF100, Philex (spit) PF100, Triax TX100 are known brands. All copper core, braid and foil are the key with foam core dielectric.

I got a screenshot of google map, marking a line between the transmitter and my street then zoomed into my street and copied and pasted part of the drawn line to get the angle - about 10° anticlockwise from the apex of the house roof.
