Freeview reception at HX2 9JY


Terrain between HX29JY 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.

hi,for viewers who have technical knowledge,is to replace the aluminum dipole in the aerial with copper wire dipole,this must be bent to look like the aluminum dipole and may improve reception,i have done this with a indoor aerial and got a locked picture from hannington at 10ft off the ground ,location nr bicester,but i stress u must have some technical knowledge.

N Mugford:

It is perfectly correct to replace an aluminium dipole with a copper one. However the dimensions are critical. So it would be better to carve an exact replica of the aluminium dipole in a sheet of copper, using the resultant item to replace the original dipole. The need to be an exact copy is to maintain the required frequency range coverage and the impedence presented to the TV set, always required to be 75 Ohms. It would also be wise to protect the copper against corrosion, especially if it were to be placed outside the property where it can get wet.

Having difficulty finding Channel MUX for new Paramount on 57. Our Sony DVR has to be manually retuned for every change, as it prefers distant Cumbria to our local Emley Moor transmitter.
can anyone help, please?

Hi mikep,thank you for yr polite reply,other people seem to be otherwise,in my eperience in using insulated copper wire seems to be fine,the tv or whatevers input circuitry seems to uncritical,i use a set top single element because im in a swamp area from oxford,before i changed it to a copper wire,in spite of the high
field strength it was troublesome,when changed to copper,hannington at 40miles,10ft above the ground produces a locked picture,the only disadvantage of copper sheet is the cost and the work involved.Possibly,in poor signal areas copper would produce a better and more stable picture,its a pity someone in a fringe area cant try it and advise,but again some technical knowledge is needed,tks............

Banacek: this seems to be a problem with todays tv circuitry,the tuner gets pulled to the strongest signal,i have a car radio that wouldnt hold a weak signal in the presence of a stronger signal,possible realign aerial or more directive type fitted.

Is the new Paramount channel free-to-air? If so, what are the required values for my 'Openbox' receiver?

I live at the bottom of a narrow valley that points roughly North/South (it's wider at the North end). Postcode is TA4 2HJ. My nearest, and predicted to be strongest, transmitter is Stockland Hill which is about 31km away to the SE. Beyond that is Mendip which is 55km to the NE.
I have installed a wideband antenna on my roof and I'm getting a pretty stable picture on CH26 (BBC1 etc.) with 100% signal quality but only 20% strength when pointing the antenna to the SW. On CH28 I'm getting 20% signal and quality but no picture. I can't seem to get any signal from any other direction on any other channels.

What's puzzling me is that getting CH26/28 suggests I'm picking up Stockland Hill which is to the SE but my antenna is pointing SW. I could just about understand it working 180 degrees out but not 90!

The only explanation I can think of is that I'm picking up a signal bounced off of the hillside. And because it's a lucky/spurious bounce I'm only getting one channel (if I move 100yds maybe I'll get 28 but not 26!).

Does that sound plausible? Any suggestions for what to try? I realise I'm not exactly in the best place for a TV signal!

Ben:

You appear to be in a particularly difficult location, valleys are not helpful to TV reception especially is they do not enable sight of a transmitter directly. There are three possible transmitters around you, but all are 'hidden' by the valley. You've tried Stocjkland Hill and Mendip, the other is Huntshaw Cross - but that is to the west so again 'hidden' by the valley.

The only suggestion I have is to try raising your aerial as high as possible - but make sure it is safe. There is no guarantee that it will solve the problem though.

Aerials receive best in the direction of its main lobe to the front of the aerial, but they always have side lobes that can receive some signals - though usually not as well. That would explain what you are seeing with the aerial aimed in the general direction of SW - where there is no transmitter! It can only be a reflected signal which will be very variable and unreliable.

My brother lives in South Molton and gets good reception from Huntshaw Cross but he is not in a valley.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
