Aerial sigal direction questions?

Hi Graham, my aerial is positioned vertically, from the pics I’ve seen the aerial is pointing more or less to storeton from what i can see.
I have taken a pic and attached of the house at the top part, hopefully so it can't be identified as such where the aerial is, would that because any interference with the roof do you think, mainly next doors at the top?
I have put an arrow to the right, would the aerial really have been better in that position?
Also on the left you can see a big mast in the background, i'm not really sure what this is for but it is kind of in-between the direction of storeton and where my aerial is pointing, do you think this may cause any issues?
I have attached a pic of this mast as well.

Looking at your photo I can't see the aerial elements. But it looks as if the transmitter is close enough to see.

That close to a 2000KW transmitter chances are the tuner front end is swamped way beyond the linear output of the UHF carrier is way higher than the tuner can cope with.

Fortunately too high a level is easy to cope with.

Try a cheap signal attenuator.

The last thing you need that close is extra amplification.

Ironically if the aerial was horizontal it would have reduced the signal considerably.

Sorry Graham think i may have confused you, that mast isn't the storeton transmitter thats just a random mast thats close by but i was just asking could it cause an issue with my signal from the storeton transmitter?

Unlikely but is does look very like the Storeton mast. This is a Google Earth ground view of the actual transmitter. Are you sure it's not Storeton ?

You could be correct, i have never thought i would be able to see it that big with the distance, think it shows as 5.5 miles away. I sshall see if i can find out if that is it, if so i will give the attenuator a try.

Thanks for your input

Pretty sure that is the Storeton mast.

You likely need a cheap UHF attenuator.

That cannot be the Storeton mast, it is the other side of the Mersey on the Wirral, not as near as that. The top of it looks completely different anyway, more like mobile phone aerials, but may be something else.

Blowing up the photo of the OP's aerial shows it to be clearly vertical.

Edit: That mast is just by the end of Stalbridge Dock on the Liverpool side of the river.

From the angle the photograph was taken, Storeton mast would need to be about 10 miles tall to appear in the frame.
This is almost certainly a mobile services (3/4/5g) mast.

Storeton (England) should not the excessively strong even at about 6 miles because it is only 0.56 kW.
