bruce tearle:

I'm sure StevensOnln1 will continue to help with your Humax issues (I dont' have one so can't), but I thought it worth commenting on terminology to avoid any confusion.

ITVX is not transmitted, it is not a Freeview "channel". It is a "streamed" service like iPlayer, All4 or My5 and many others you'll find on a Smart TV or Box that has an internet connection.
ITVX will not work on some boxes or TV's with older technology but All4 should continue to work at present as far as I know.

I-player is working fine as is Channel 5 and all of UKTV.

bruce tearle: I can't find anything on Google about any issues with All4 on your box. I only have a Humax Freesat box, which All4 was removed from several years ago, so can't check for any similar issues here. I take it your Samsung TV doesn't have the All4 app? My 2016 Samsung 40" got the update to ITVX so presumably yours is an older model. I think your best option is probably to contact Channel 4 Viewer Enquiries via the email address or phone number at the link below and explain what you've told us to see if they have a solution (please come back and let us know how if they manage to solve it).

have e-mailed Channel 4 but no response as yet.

connected my laptop via HDMI link and had not trouble getting channel 4.

It's frustrating because the HUMAX/Sansung combination did work in the past. just can't think what I could have changed that is causing the problem.

Mrs. Pocock : We need a full postcode to see the predicted coverage at your location. Also, please note that the contributors to this website are all volunteers who have no connection with any broadcaster or the company running the transmitters.

Mrs. Pocock :

Personally I wouldn't use any washing powder to receive Freeview :)

I've managed to find a postcode for that beach area.
You'd need a Group K aerial.
Whilst there are some local relay transmitters, they won't give you all the channels and signals will be a bit unreliable down there on the beach.
You should be able to get good signals from the main Mendip transmitter (West local news) or Wenvoe (Welsh local news). Wenvoe signals should be stronger.

Considering that you are likely to have problems with seagulls (and maybe other birds) perching on aerials and causing damage, you need something fairly sturdy.
I would tend to go for something like this Blake Log Periodic -
56 Element Log Periodic Group K Aerial - Blake UK

You'll also need a suitable pole and bracket to secure the pole to the chalet.
The aerial should be mounted with the rods horizontal. You'll need an F connector to connect to the aerial and some double screened cable similar to CT100. And of course a coax plug for the TV end as well as someone who is competent at fitting the plugs etc.

The aerial should point at Compass bearing 86 degrees (that's almost due E) for Mendip 57km away.
Or pointing at Comp[ass bearing 20 degrees (that's almost NNE) for Wenvoe.
