My postcode is Pa384bs and suspect I need to replace my aerial. What type of aerial is suitable? The aerial is 130 metres from the property.

J G Lobb:

Do you really mean 130m? That's an extremely long distance - more than the length of a 100m drum of cable!
I assume you maybe in a bit of a valley, and the aerial is mounted up on top of a nearby hill if so.

You will need a Group A aerial BUT the rest will depend on the rest of the installation and what you intend replacing, if anything.

I assume you have a masthead amplifier. What type/model is it? (I'd be thinking about something like the LABGEAR KIT125VK which has 5G filtering as well as variable gain upto 25dB)

You should have the filtering as there is at least one mobile phone mast nearby and future upgrades may give you a problem with interference due to mobile use of the 700MHz band.
If interference is something that's started recently and this is what has prompted you to think about replacing the aerial not realising what the issue is, then you should be able to get a free filter from https://restoretv.uk (put that into your web browser for information).

What coax are you currently using? You really should use CT100 type cable (double screened copper coax).

Chris.SE: I live west coast Scotland. Torosay transmitter 30 miles away. Aerial 150 metres away with Proception masthead amp 27 dB receiving 12 v from distribution amp in loft.All 3 tvs show no no signal. Please could you advise steps to check system?

J G Lobb:

Now that is a tricky one!
I trust you haven't retuned whilst you had no signal, if so, this may have cleared your correct tuning, so try a MANUAL tune of Torosay's UHF channels as listed at the very top of this page.
Other than that, it's possible there is unlisted Engineering, but feel free to proceed with any checks you want.

Firstly check the aerial is intact and still pointing correctly but do a visual check of the cable en route to see if there is any obvious damage. Check the aerial and other connections whilst you are there for corrosion etc.

Do you have a (digital ideally) voltmeter so that you can check that 12v supply.
First unplug the feed to the masthead and check that 12v is present on the output of the distribution amp. If it's not, there's the problem.

Even if it's there, the distribution part of the amp may have failed but checking that will either be by taking it somewhere where there is a signal (a friend's) and connecting it to their aerial output and see if the outputs provide signal to their TV. Alternatively by substitution, but that means buying or borrowing another so probably best left as a last resort, or of course getting it professionally checked! Probably best to check the rest of the system first.

If 12v is ok, then check if it is arriving at the masthead amp,

If it's arriving at the masthead, and all other checks are ok, the masthead itself may have failed.
In your situation I cannot think of anything other than get it professionally checked, but read on first.

If it's not arriving at the masthead, there could be a break in the coax cable somewhere. Finding that may be difficult. You'll probably need someone to help and an ohm-meter or continuity tester.
Disconnect the cable at both ends and then short together one end and put the ohm-meter or continuity tester on the other, then work your way along the cable flexing it slightly to see if you can find a break where your friend sees a reading which wasn't there to start.

If everything else checked out ok, then if you still have no signal you ideally need a signal strength meter you can connect direct to the aerial so see what you are receiving. There are currently no reported faults that I can find, and as previously mentioned the transmitter is not currently listed for Planned Engineering but there could still be work in progress in which case i would expect signals to retune later in the day.

I don't know if anyone else has any bright ideas about checks that I may not have thought of.
