Poor wifi

[GF1]

I am a seasonal pitch in North Devon and the site WiFi is intermittent. I am thinking of installing a modem with SIM card. Advice please on:
Internal or external?
Need for an antenna?
Which equipment is recommended?
The set-up needs to provide a good signal for my mobile phone, smart TV and laptop. Not all at the same time though.
Any advice or articles on this would be much appreciated.

How good is the signal on your mobile phone when you're in the caravan - if it's good, you could use it as a hotspot - if it's poor, you need to research which network gives the best signal there.

Which site?
It will make a huge difference.

I am in a similar situation, site WiFi being "rural" and much slower than available 4G. I just used my large cellular data allowance and phone to downloaded programmes to whatever app, then used device screen mirroring to my FireStick to watch on the TV.

Only time this fails, is if I can't download a film/video and need to stream; phone can't handle doing both downloading and mirroring at the same time so it's unwatchable. However, I don't really use it like that much, so investing in a fixed solution isn't on my list of priorities.

Good videos on the subject and on how to install the Avtex WiFi device. But it needs a hole in the roof for the antenna.

Excellent point - You can use the Mobile providers website to view their coverage maps. e.g. O2: https://www.o2.co.uk/coveragechecker
