Freeview reception at FY8 1HW


Terrain between FY81HW and Freeview masts

For reliable and stable Freeview reception, you need an unobstructed path between the TV aerial on your roof and the digital TV transmitter.

The diagrams below show the transmitters you can get a signal from - in order from best to worst. The blue line tests the line-of-sight between an aerial 10 metres above ground level (the line is red if there is an obstruction in the line-of-sight). You may be able to improve reception by raising the aerial higher - for safety's sake consult a reputable aerial installer if you need rooftop access. See below the diagrams for advanced options including selecting the receiver aerial height.

The terrain information (from Ordnance Survey and GIS) does not include forestation (where leaf cover changes with the seasons) or city buildings. The line-of-sight line can appear curved as this straight line moves over the Earth's surface.

RDD: You could do what I've done, and have for some years - split the feeds from the wall. I originally did it when it turned out that my PVR was much more sensitive than the freeview box, after getting a new aerial.

One of the reps at work (who'd formerly been a TV installer) kindly made up a set for me, but its easy enough yourself.A decent bit of coax out of the wall socket, then a good quality splitter, then two cables off that, one to the PVR and one to the TV. Mine has F-fittings, but whatever works.

Then you can vary the attenuation seperately, and looping through isn't an issue. I got a variable one, but it didn't seem to do much, so I got some from Amazon (the same as these https://www.maplin.co.uk/…59p) which fit into one another, so you can buy perhaps a 3db, a 5db and so on, and put them in series to get the right level.

The trouble with a masthead amp is that you can't just switch it off (my new house has one), but at least you can dampen it down.

MikeB:
Thanks for the suggestion. My concern is that splitting at the wall will lower the signal to the DVR which is already at circa 55% . However this could be due to the tuners of the DVR being less sensitive than the tuner of the HDTV..

However, I will give it a try and see what happens, I think I have enough bits a pieces to rig your suggestion up.
I will let you know. Thanks.
