We recommend a high gain wideband TV aerial for Freeview DVB-T reception from the Sandy Heath TV transmitter. Many homes served by this transmitter will need an aerial upgrade to get good Freeview reception as a high proportion of existing TV aerials will be Group A, which will give very poor reception.

If retained, Sandy Heath Group A aerials will give poor Freeview reception on all DTT multiplexes, as all Freeview channels from Sandy Heath are transmitted on UHF channels between 40 and 67 - well outside the frequency range that a Group A aerial will receive.

The Group A aerial is designed for channels UHF channels 21 - 37 only. Only in areas very close to the transmitter will DVB-T Mux B be receivable on a Group A aerial.

Sandy Heath Freeview Reception Problems

If some Freeview channels are missing from your channel line up start by checking your aerial. If you are getting Freeview reception problems from the Sandy Heath TV transmitter, start by checking the signal quality on the Mux B UHF channel 67 DTT multiplex. If Mux B signal quality is very low compared to the signal quality on Mux C (UHF channel 40) and you are well inside the DTT coverage area from Sandy Heath, it is possible that your installed aerial is not the required wideband type. In this case, you'll need to buy a high gain wideband aerial and get it installed by a CAI registered aerial contractor. Alternatively, if you live in a strong DTT signal area, you can try installing a loft aerial yourself. High gain wideband aerials are available from eBay.co.uk. A suitable wideband aerial for Sandy Heath Freeview reception is a Triax 52 element array.

If you're using an indoor loft aerial for Freeview from Sandy Heath, it's worth noting that the higher the UHF channel number being received, the more TV signal attenuation will be experienced through trees, roof tiles and walls. Therefore, it's likely that Freeview Mux B from the Sandy Heath TV transmitter will be received at a lower signal quality on an indoor aerial than the other DTT multiplexes, even with the correct wideband aerial. This is because it is transmitted on one of the highest UHF channels (67).

The best solution is to use an outdoor TV aerial mounted on the chimney, to eliminate signal attenuation caused by the roof tiles. In fringe DTT reception areas, Sandy Heath Mux B may not be receivable on an indoor aerial. Mounting a UHF TV aerial in the loft will typically halve the received TV signal.
