TV box to record with poor signal.

Rodders53

Amplifying a poor signal won't help one bit.

Aerials for caravans and boats – A.T.V. Poles, Brackets, Clamps & Aerials and Splitters, amps and diplexers – A.T.V. Poles, Brackets, Clamps & Aerials may help to explain why.

If your existing box has red/orange writing rather than purple then ditch the roof flying saucer aerial for a directional log periodic connected to that existing amplifier. {It's probably the Status 350 equivalent from when the caravan was made}. If the box is purple then it's a power supply to the amp built into the outside flying saucer unit.

Justin of ATV sells a kit Aerial kit (Caravan) – A.T.V. Poles, Brackets, Clamps & Aerials But one can do similar by buying individual items from elsewhere.

You could even upgrade the omni to the latest directional version if competent at caravan DIY and roof sealing… STATUS 570 Directional Digital TV & FM DAB Radio Antenna – Vision Plus

Edit: Almost all TVs and PVRs have signal diagnostic meters that can be seen when manual tuning or under a Diagnostics menu… some brands make it harder than others to find and use. Higher Q quality is more important than high S signal level.

I would echo what has already been mentioned. No pre-amp will help at all with a mediocre antenna. Pre-amps are really to overcome long runs of coax cable, or to overcome the loss in a splitter. Neither of these scenarios are relevant in the case of a caravan.

The solution for terrestrial TV reception is a larger aerial on a pole, or to pick a pitch with a view of the sky towards a compass bearing of 164 degrees, and use a dish with Freesat.

If there's a poor signal then an amplifier will probably make it worse by amplifying noise.

The only answer is to use a better aerial and locate it higher up, although if there's not a lot of signal then even that may not work.

What sort of aerial have you got at the moment, if its an omni then you really have no chance. A decent log-periodic on a pole would help like this - https://digitec-aerials.co.uk/log-periodic-tv-aerials/ pointed towards the transmitter and oriented correctly (Kings Lynn is vertically polarised and only has a subset of all the available freeview channels)

Belmont is in Lincolnshire at a bearing of approx 320 degrees from your location and is horizontally polarised.

exactly this terrestrial TV is UHF

there are simple rules for UHF

1. Height is might
2. gain eases the pain
3. good feedlines get the most signal from the antenna to the reciever

FWIW my PVR does a much better job on a weak signal than my TV or TalkTalk box.

I'm not going to give the model as it's long out of production.
