Freeview reception at AL5 4QH


For reliable and stable Freeview reception, you need an unobstructed path between the TV aerial on your roof and the digital TV transmitter. The map below shows the transmitters predicted to provide a signal at this location.

You can click on any transmitter symbol to show the coverage area as a green overlay on the map. Double click on a transmitter symbol to go to the transmitter information page.

You can also view the ten closest potential '4G-at-800' mobile phone masts within 1.5km of the selected location - these masts may be used for 4G-at-800 mobile broadband services from 2013-2015.

Bishop's Stortford

I live in bishops Stortford CM234PB and the free view maps show that my aerial should point towards sandy, but they actually point to crystal palace. However, I see that there is a booster transmitter in bishops Stortford that is within range, which of the three transmitters should my aerial point towards please and does my existing aerial work for the other two transmitters or do I need different aerials?
Thanks

The signal in Hull has been bad these last few days then last night we lost every channel, still same this morning. Almost wasted money on aerial guy, because we get no warning or info about signal problems, Surely something is wrong in Hull with signals
HU5 5DT is my postcode but other people in HU5 area are also affected

Gary k: Your aerial should point to the one you want to point it. There is no compulsion to use any particular transmitter!

The Bishop's Stortford relay transmitter carries only PSB (Public Service Broadcaster) channels, so you might like to use either Crystal Palace or Sandy Heath, if at all possible, so as to receive all channels.

It would appear that you are on the edge of the area served by the Bishop's Stortford transmitter and that you might potentially find the signal degraded at times due to interference from other high-power transmitters which use the same frequencies.

I suggest that the area that the Bishop's Stortford is intended to serve is that low-lying and near the river. This presumably has difficulty in achieving reliable reception from Crystal Palace.

Crystal Palace uses Group A channels exclusively and if your aerial is a Group A one (red tip) then it won't be suitable for Bishop's Stortford relay or Sandy Heath's COMs.

See:

Aerials, TV Aerial and Digital Aerial

Sandy Heath's PSBs are Group A and its COMs are top of Group B/bottom of C/D. Thus, for Sandy Heath an aerial spanning at least Group K is required.

For a list of PSB services and a list of COM services, see:

DTG :: DTT Services by Multiplex

Whilst Sandy Heath is only 24 miles away, line-of-sight is obstructed 13 miles away, due to the high ground around Therfield.

The effectivenes of yagi aerials on lower channels (frequencies) isn't as good on higher channels, so for Crystal Palace either use a log periodic or Group A yagi:

Crystal Palace Transmitter

You appear as if you might have line-of-sight to Crystal Palace (this excluding any obstruction on the ground such as buildings and trees):


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


The area between the yellow line and the pink one is known as the first Fresnel Zone. Objects within it can adversely affect reception. The ground from you up to Sawbridgeworth and the high ground around Epping Green are all within or near to it. For that reason, even though you have line-of-sight you could potentially have difficulty.
