TV transmission does not work as you seem to think.
Please would you gove a full post code of your locvation so we can check the receptions conditions there. Would you also give us the signal strength readings.

I don't get that problem at all, the green coverage overlay is still showing as before. I use a laptop running Windows 8.1.

I've just tried Opera, Chrome, IE11 and FF in W8.1 and all seem OK to me with the expected overlays. Seems odd that it differes unless we are being provided with different versions. Briantist does say he is testing.

Michael Watson:
We need a full post code to be able to consider what may be the cause, Giles Gate / Durham is not accurate enough to get specific details of transmitter, reception conditions, terrain, etc - all of which we use to seek possible causes of your problem.

Seeing something different? We are doing A/B testing on a new

Briantist:
Found a problem with the prediction page. My brother has just moved to an EX36 3DY - but the prediction suggests he is served by Emley Moor in Yorkshire whereas he is in North Devon!! Please can you correct whatever is causing that major error?
I've also found that some of the coverage mapping does not show the green covergae areas, as others have said above. For me it's a bit irregular and I haven't found and rationale to explain it yet.

R Murchie:
If your satellite reception is seriously affected by weather then you either have the wrong size dish (too small) or an alignment fault. The oft fitted 35 cm dish is far too small for most parts of the UK in my extensive experience. The smallest for your area should be at least a 50 cm or maybe a 60 cm one. (I use a 60 cm in Trowbridge and have no weather problems.) So with a decent size dish your Freesat reception should be very good and uninterrupted unless we have a blizzard of polar proportions!
Your TV licence is to allow you to operate TV receiving equipment to watch live broadcasts or catch-up on the BBC iPlayer. So Ofcom will probably not respond to your suggested enquiry.

GeordieLad:
Any passive aerial splitter will contain 3 resistors of 37 Ohms configured in a 'star' formation, one leg being the input and the others the outputs. I know of no splitter that is as basic as you describe. The main issue with passive splitters is the impedance mismatch you mention and the standing wave problems if the cabels are an unfortunate length. Plus the degree of signal loss with any such passive arrangement.
An active splitter would normall isolate each output so leaving one or more unterminated by a TV would not be a problem.

Eugene MC Geehan :
An indoor aerial, in the same room as the TV, has always been poor - even in the days of VHF 405 line TV!
An aerial in the loft would always be better but one outside the roof is always best, if possible.

Dave:
Would you please give us both a full post code and the signal strength readings for several channels. Then we may get some ideas on how to proceed and p[otentially resolve the issues.

P R Kenny:
It could be an indication of either weak or strong signals. The ony way to tell is to check the signal strengths indicated by your equipment when there are no aircraft around and again when recpetion is being affected. Ideally you want between 55% and 85% for SD channels and between 60% and 80% for HD services. If your signal is less than that, check all your aerial connections first, bad connection play havoc with reception. If the strengths are above that indicated then you need to reduce it by fitting an attentuator.
