The symbol shows the location of the The Wrekin (Telford and Wrekin, England) transmitter which serves 280,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Some yagis have reflector elements that are wire; others a sheet with holes in it. Is the latter better at keeping out rear signals?
John Low - if you know what is happening, you may be able to avoid unwanted channels(broadcast) by disconnecting the aerial whilst the box is scanning that frequency.
Brian - Is there approved terminology to distinguish between "Channel" a transmission frequency and "Channel" a programme?

Just prior to the Wrekin Switchover I was able to record digital channels from my TV onto my non digital video - using Ext 1
Since switchover I cannot do this.
I want to be able to still record to my video. How can I do this now?
Someone has suggested connecting a freeview box to the video - (although I have a digital TV). Is there any point to this?

Robin Oliver: if your video has its own dedicated freeview box you will be able to record a different channel to the one you are watching and also record when the tv is switched off. You just have to remember to set the freeview box as well as the VCR for timed recordings.

Robin Oliver: If you did a factory reset when rescanning for switchover you might have changed the settings in the menu for what is available on the output on Ext1. The switchover should not have changed the facilities on your tv (except for receivers not supporting the 8k mode which don't receive signals post switchover). Selecting the required option in output settings might be all that is required.

Following the recent updates to the Wrekin transmitter I still cannot pick up any HD channels on the Welsh border near Oswestry.
Why is this, am I missing something mindnumbingly simple?

NickA - do you hgave an HD Tuner?
"HD Ready" does not mean all you might think!

Steve: My understanding is that the length of the reflector elements is more important than the number and type.
The stamped plates are usually indicative of 'contract' aerials which have relatively poor gain and usually uneven gain across the band.
Justin Smith of AerialsAndTV.com performed some tests with the reflector missing and fitted incorrectly at Aerial Positioning Tests . Bill Wright has written about short reflectors at http://www.wrightsaerials.tv/articles/whatsat-short-reflector-syndrome.pdf . I'm sure I've seen one of them comment on folding the reflector plate to reduce its height, with no noticeable impact on the performance, though that probably matters more for vertical polarisation acceptance angle than for the horizontal example.
Briantist: Please look at some polar diagrams at Aerial Polar Reponse Diagrams . The claim that aerials work nearly as well behind as in front is completely unsupportable. If the reflector is missing, this is possible, but if all elements are intact, it's simply untrue. The diagrams show -20 to -24 dB front to back in the examples.
Digital UK's predictor only allows for -16 dB of attenuation, based on ITU-R recommendation P.419-3, so it can indicate co-channel problems that turn out not to be a problem.

Steve - up the Trefonen Road, good line of sight and BBC1 comes in at high 80s % signal strength.
Noticed some of muxes on Wrekin still low power till Sept upgrade - any relevance?

NickA: The *commercial* muxes - SDN, ArqA and ArqB - remain on pre-switchover channels at pre-switchover power levels. The HD multiplex has launched at full power and on its final channel.
If BBC One is working reliably, if your equipment is Freeview HD-capable, you should get reliable HD channels (but do see Single Frequency Interference).
"HD Ready" does not mean it can receive Freeview HD signals. It means that it can handle HD-format pictures supplied by another box. Freeview HD uses a very new transmission standard only completed in mid-2009. You must look for the Freeview HD logo.
