From location SA67 8BB
Using freeview.
Aerial on roof.
Good reception on most channels.
However typically can not receive all BBC channels.
This has only been a problem over recent months.
Trying to also find correct compass direction for aerial to point to Presely mast.
Is there a internet site to access to find compass directions to nearest mast?

John Cook:
If you look at the boxes inserted below your post and open the 'digitaluk trade' one iot will give you the details of the recommended transmitter. In your case it is indeed Presely and the aim angle for your aerial is 36 degrees east of north.
Hope that helps?

John Cook: You can also click on the first three links to see a map, or a terrain plot (with compass directions) or all the data. Freeview reception at SA67 8BB for example shows the 36 degrees too!

I have conducted several several retuned and programme scans, but I am not satisfied with the quality of signal received from the Presely transmitter.
My location is Gwaun Vale Holliday and Touring park,llano hear SA65 9TA.
What is the best antenna to receive a good quality signal from the Presely transmitter?
Thank you

I am on the Gower just West of Swansea. Poor or no reception on the lower MUX's due to the high barometric pressure, and likely to stay like this for a few days. Ah well at least the weather is good.
