The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 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.
Are there any planned engineering works or unexpected transmitter faults on the Sudbury (Suffolk, England) mast?

Chris SE,
I have been in touch with Blake. I believed logs were meant to be good at rejecting signals from the rear. They say not and that their DMX range are better. Since their largest dmx is pretty much the same as what I have made myself, I doubt I would see any improvement.

I'm totally surprised that someone from Blake has said that logs aren't good at rejecting signals from the rear, they are, and very low/no sidelobes, they are also good at impulse noise rejection, good cross-polar rejection and they also have a flatter response and considerably less wind resistance!
Perhaps you were talking to someone from Sales, just wanting to flog you a more expensive aerial, they're at least 10 & 20 more depending on the number of elements!
I suggest you get back in touch, ask for technical support and ask them if they can email you the polar diagrams for the DMX10K-F and the BLA-LP56K
In the meantime have a look at this from ATV Aerials and TV
Their XB10 range is almost identical to Blake's DMX10s

Compare to this
Aerial polar response diagrams A.T.V. Poles, Brackets, Clamps & Aerials
You will note the absence of sidelobes and low rear rejection for the LP in this second graph top LH plot.
You will find similar information from multiple sources (not just the sellers) if you bother to do the research. Frankly, you have no idea exactly what your homebrew aerial performs like unless you have had it professionally tested. It could have a very peaky response, have particular problems with 602MHz - C37 etc.etc.
You have been bleating on about the C37 problem for months and months, so long I've lost count. Yet you seem unwilling to take the simplest of steps to eliminate possibilities, the free Filter to eliminate Mobile signal interference. The problem may go away and your home brew could continue to give years of service. If it doesn't then my next choice would be a decent well made LP as already suggested, but you try what you like.

Chris SE, thanks.
I was communicating online, and he sent diagrams. It started with your advised log but ended up with the highest gain which from the 'x' type.
I have made extensive tests with my homebrew, just for my own interest, testing at each tiny change. I have altered spacings, length of elements, width and height of reflector and it is one of the few that gets 37. lengthening of elements brings better signal on 29, but if I do too much it loses on 47. I am particularly proud of the dipole which I call batwing, substantially larger than most.
Any more thoughts on 1.5v lithium batteries?

Does anyone know about freesat, please?
I used to get all channels. Now Sky news and others break up or disappear with a message about weak / no signal.
Why does this affect only some channels?

The transponder that the Freesat Sky News is on happens to rank 55th out of 60 in terms of link margin, with a value of 5.1, according to recent scans of 28E with one of my satellite TV cards.
Link margin is the excess, in dB, of signal to noise ratio over that required for error free reception.
Thus, under unfavorable conditions such as rain, blockage by trees etc., that transponder would be one of the first to go.
If Sky News is your requirement then you could, perhaps, manually tune to 11837H in non Freesat mode, where you will find the ROI version. That transponder also carries the Freesat channels Together TV and Challenge - its link margin is much better at 9.9dB - ranking 11th out of 60.

Did you get a filter for your Freeview, and how did it go?

js,
thanks. You mean it is KNOWN to be inferior? They don't try to improve it?
A bigger dish would not help?
This other version of it, is that from Sky?
I would not know how to tune my recording box to get that.

Yes, I know I am an ungrateful sod. I never got round to it. I will do though. At present it is not causing problems, but if the weather heats up it will be a pain and I will do something.
I have been using freesat a bit, but now have a similar problem with that one on some channels.

No, not known. All that is supposedly known is the beam used for transponder - UK or Europe.
Astra 2E / Astra 2F / Astra 2G (28.2E) - All transmissions - frequencies - KingOfSat
Do you receive 164 Together TV and 146 Challenge without error?
They are on:
11837H 27500 5/6 DVB-S QPSK
which also carries Sky News ROI on BSkyB
and which, on my system at least, has a much better SNR than:
12071H 27500 5/6 DVB-S QPSK
which carries 147 Sky Arts and 202 Sky News.
What hardware are you using for satellite?

will get back to you re those two channels.
The pvr is Echostar, about 12 years old.
