I once used UK Free TV to ask its users if they could name what I thought was a transmitter mast in the distance as I could see something with red aircraft warning light lit up in the distance, turned out to be just a chimney tower at a power station.

This time I would like to ask if anyone knows what the 5 transmitter masts are all used for, very close together around Newton, near Frodsham in Cheshire?
There are two off Simons Lane which on Google Streetview shows a little car parking area with the names 'Beacon Hill' and 'Sandstone Trail'. There is one on its own, East off Dobers Lane parallel with Manley Road.
There are three, North at the junction of Dobers Lane with Meeting House Lane.
I'm curious why the need for so many in such a small area? Why not just build two or three larger ones on the same land as each other?
Anyone know what purpose each mast is used for?
A friend told me once that there are radars used for Air Traffic Control for Manchester/Liverpool airports on the top of the Helsby Hill, though these masts I have written the location of aren't really in Helsby as such.

Am I correct about these?
Can anyone else give me any more details and information on these masts?
I see them to and from work so just curious about them as I'd like to take a trip up there and see them sometime.

Thanks,
Stuart.

Gillian: Sounds like you have a sick aerial system, so that the bulk of the channel are lost. Check your signal strength and your system.

Gillian: A terrain plot shows quite a few obstructions by the terrain alone, with objects on the ground no doubt being in the way as well:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


At 10 miles away you have the high ground of Bredenbury. And between 4 and 7 miles out there is also ground in the way.

As signals travel in straight lines, you are having to rely on them bending around the obstructions. Different frequencies bend to differing degrees and changes to the objects they are bending around can result in changes in reception.

While, as MikeB says, it could be your aerial system at fault, variable reception may be an occupational hazard.
