How do I switch away from Hannington? Do I have to re-point the aerial?
Sorry - I answered "How do I switch TO Harrington" but the same ideas apply to wherever you try. Be aware that the repeater transmitters don't transmit all stations - just the major ones. If you choose a repeater, you will have to orient the aerial vertically and you may need a different aerial from your current aerial.
Rowridge is a Main transmitter transmitting on 21-37.
See http://www.digitaluk.co.uk/reception_guide for aerials.
1. You need to have the correct aerial for Hannington so that you can pick up the channels it is transmitting (32 to 45). If you were previously using a repeater transmitter your aerial will be vertically aligned and will probably be the wrong group.
You need to point it towards Harrington.
It needs to be set with the elements vertical or horizontal as required. As Hannington is a Main transmitter, set it horizontally.
Ideally it should be mounted on a "cranked arm" so you can move it nearer to or further from the transmitter by a foot or two to ensure the aerial is not located in a null for any of the channels you need. (It's like a car radio. You pull up at, say, a traffic light and the radio goes noisy because the aerial is in a null. Ease forward 12-18" and you move out of the null and the radio is OK.)
Look at your neighbours for clues.
2. Reset the box. Now do a Manual Tune selecting only those channels the Postcode Selector says Harrington transmits.
3. If you are using "traditional brown TV Coax with copper braid" chuck it away - it is useless for Freeview. Replace it with "satellite co-ax" which has a solid foil sheath.
It may be easier to get an aerial installer, who has a signal strength meter, to install any new aerial.
What is your postcode so I can look at the checker.
