The symbol shows the location of the Waltham (Leicestershire, England) transmitter which serves 770,000 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.

See previous posting please:
Ar ha, my antenna is slightly, cause of brackets not being equal so to speak, pointing down, which is why with slight wind also it appears to dive the signal up and down.
So my question now is, or guess, maybe BBC on ch 61 is higher up the mast, or lower, or whatever, anyway, meaning if others at different heights, mean I need to tilt mine back and might improve it more still, cause obvious I can not easily get it, and if necessary, though picking up Allesley Park, strange, must be amplifier, I can increase gain still, but first I'll try tilting it back some.

Wasted money then as I think I found my answer on a web site:
Note how the MUX 5/6 antennas are almost hidden on the NW face of the mast so as not
to broadcast in the direction of Sandy (which is SSE) and cause co channel interference.
A similar situation existed with MUX1 and Emley Moor (to the NNW) and Oxford to the SW,
Information on radiation patterns can be most useful, and I cannot for the life of me understand why it is not more widely publicised.
And of course that's the one I want channel 57, but still not explain then why only one I get is 61, and not 54, both at 50,000 kws and should be facing the same.
Waltham TV Transmitter
In fact they are, all around, but bit lower down the transmitter, so whether that is the factor, but makes no sense, cause I'd least expect something, say red and 20$ or 10% on the reading signal quality meter, get 70% mostly on average on the signal strength one, not sure lowering and increasing gain further might help, maybe.
Or to try Oxford, or whatever else, being in a dip, pot luck and when windy no chance, wish now in hindsight paid for someone to do it on chimney one, but had this hassle years and years back, but with powers increased and amplifiers now allowed as such, surely one would think, great, I stand a chance now of getting something.
Just in case, maybe also, might be that I'm on some relay or something weird, about to check other digital channels that might be on 794mhz ch 61 etc.
But as it says East Midlands, I suspect it is Waltham.

Does anyone have an accurate idea of when the work to the Waltham tower will actually be finished? I've setup the inlaws and their neighbours to Waltham a couple years ago and gave them the completion dates posted at that time. However, the ongoing issues are causing them (and subsequently me) continual problems and I would like to be able to give them an idea of when it will actually be finished. I understand that it has only been 13 years since this whole process was started, but they wonder if it will be done in time for the 2012 Olympics or if they should get freesat while the deadlines get extended on the freeview changeover. Keeping in mind that as pensioners they are averse to learning new systems

YAY, lowered and increased the signal, likely 20db gain now, but might still need max, loaded them, but playing up badly, see previous posts for what I'm on about, anyway problems sorted it seems, now one has to always hope for now wind, lol, fat chance, especially this time of year, :(.

Billy: That is old information. ArqB now transmits from the main antenna, which is unrestricted. However, there may be a clash with a relay that uses C57 for a different service. Can you provide a full postcode, so we can check the predictions?
I don't believe that a 20-odd element Log Periodic can have even 15 dBi gain. 6-7 dBd (=8-9 dBi, 0 dBd = 2.15 dBi) is much more likely. You could be reading the front-to-back ratio, which is also very important - this is just measured in dB as it is a ratio, not a quantity.
All relays simply retransmit what they received from the parent transmitter - all relays of Waltham will say 'East Midlands', including Nottingham which is fed via cables rather than off-air.

Steve: The only remaining step published is SDN to change to 8K mode and increase in power (and presumably move to the final antenna) on the 12th of October.
There may be engineering works to dismantle the antennas used for low-power digital services before switchover. The masts are now shared with mobile phone companies and carry DAB and FM radio services, any of which might require new aerials to go up or existing ones to be changed, which might occasionally cause interruptions, but major re-engineering shouldn't be required for another 40 years.
There is also going to be another retune at some time, to free up C61 for 4G mobile phone services. This depends on getting international clearance for whatever channel gets used in its place, so we don't yet know when this will happen or even when we will know.
In the international planning for digital TV, we did ask for C35, but that might still be released for other purposes, or for new multiplexes - it's unlikely to be the new home for BBC A or for one of the COM muxes, if one is bumped out of the way for BBC A to use.

No it was from maplins, not the advertised one, so better still, at the max now, 22 element log perdodic with 25db gain amplifier.
Ironic, cause only get two well and the one being what I needed for sky sports on ch 57, odd glitch some times but compared to years back, rare.
Off top of my head, yeah think the antenna itself is only 7.5 db gain, it does pick up another station close by despite it being vertical, lol, but it finally works.
Worry is the wind and rain, especially with ex - hurricane Katia coming in, though that's mainly gonna effect northern UK more.
Thank you any way Mike for your kind reply, but, so lucky, out of all of them, the one I really wanted I got and rang top up tv already, no lets just hope it stays that was, being in dip and getting waltham over 40 miles away is a major coup for me, and so much better than over 10 years back.

I Live in DE3 and since the DSO at Waltham my signal strength has decreased on all multiplexes. I use a high gain wide band aerial and before the DSO had a good signal. Now the signal regularly changes strength and drops out.
I have tried retunung options and checked for excessive power but neither solved the issue any ideas.
Channels 57 and 61 seem the worst.

LE14 4PE (Waltham transmitter)
just back from holiday, have retuned our TVs - all ok except one attached to an old Pace set-top box which finds only the 24 channels on Mux A (ITV3, QVC, Bid, ITV2+1 etc), have tried attaching to a different aerial that is used by one of the TVs that retuned correctly but still just those 24 channels, this digibox worked fine until the August changeover
- any ideas?

Is your Pace box on TVs and boxes that do not support the 8k-mode | ukfree.tv - independent free digital TV advice
If so, you need a new box and you will receive nothing after October 12th.
