Freeview reception at PO20 0SU
Terrain between PO200SU and Freeview mastsFor 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.

Firstly there is no such thing as a 'digital' aerial. All UHF aerials of a wideband type will receive all the available signals, the type of modulation does not affect how it is received.
Secondly, please check all your aerial cables and connections, if there are coaxial plugs/sockets please unplug those and the refit.
Thirdly, check the signal strengths of the affected multiplexes, You want to have between 60% and 85% ideally, too much or too little gives bad results.
