Thanks. Would you advise a high gain aerial or a wide band aerial for this area?

Paul: You need a wideband (all frequencies) aerial if you want to receive all the multiplexes.

You don't really need anything more than a standard one after switch-over is complete in 2012. A high gain one will get you no additional benefit.

Hi. I'm no technofile when it comes to TV so here goes....

Sudbury transmitter area - based in Ipswich.
Outside aerial in loft.
Although on top of a hill, the position of the house means the aerial has to point at a party wall to face the transmitter.

Using an amp, my analogue reception on BBC1 BBC2 ITV are A1. Channel4 is a B+ and as usual Channel5 is a D- (but then so are the programmes)!

Have full set of squares on the test pages on BBC1 BBC2 and Anglia but cannot get teletext / ceefax on Channel 4 to test squares on that channel as suggested by the switchover pages on Ceefax.
Have Philips set top box but it cant find any Freeview channels at all.
Have tried replacing aerial with brand new AllForOne SV9351 (outside) aerial in loft to no advantage - in fact all channel pictures are slightly worse.

Question 1 = Is Ceefax / Teletext available on Channel4 in my area. Is my inability to get it indicative of why my set top box can find no Freeview channels?

Question 2 = Are Philips DTR220 set top boxes any good, as I have read many poor reviews since I purchased it a couple of years ago?

Thanks for the link to this site's incompatible kit list Briantist.

Just another point for readers - in the case of my elderly relative's Panasonic iDTV (a TX-32DT2), I contacted Panasonic by email ( and, after confirning that the iDTV could not be modified internally for 2k/8k working, offered a payment of up to £25 (against printed or emailed proof of purchase) for the purchase of ANY Freeview set top box to enable continued use of the iDTV.

Whether other manufacturers will be as generous I don't know but I have my cheque! (TQ2546538159).

The info re Mux 2 for Sudbury is not entirely correct. Mux 2 is broadcast on Ch2 68 and 56. To the SSE of Sudbury only the Ch 56 transmission (Sudbury B) is receivable, but the ERP of this transmitter is only 1100kW, which means that the signal does not radiate fully to the full distance of the area. E of Colchester towards Clacton only high-gain aerials high up and with amplifiers will receive a sufficient signal.

Heinz: That's very good of them, sadly many companies don't seem to regard their reputation as important.

Aytchgee: Your location should provide very good reception of all multiplexes, with only multiplex 2 being poor.

However, this requires a rooftop aerial that is actually on the roof.

If you use a wideband rooftop aerial, you will certainly get all the channels now and after switchover.

You are experiencing a typical problem for a loft aerial.
