The symbol shows the location of the Crystal Palace (Greater London, England) transmitter which serves 4,490,000 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 Crystal Palace (Greater London, England) mast?

I can't receive COM7, CH33 in Iver Heath SL0 0PT, although all coverage maps show strong signal. I know 100% that for example Talking Picture channel 81 definitely worked on the same receiver before, now it is gone. I tried all sort of reset/ retuned without cable then tuned again, nothing helped.
My Polaroid HD model DTT 1810 shows no signal on CH33, all other CHs up to 29 have good signal.

Alex : Whats your signal strength? If the remaining muxes are low, points to the obvious - you've got a problem with your system, and the whole thing is gradually going. Frayed cable, etc most likely reason. Start with the fly lead from the back of the TV - swapping it out is easy, cheap, and might cure it. If not, at least yo know its not that and then you can follow the signal path back.

Well I bought an indoor aerial and can get all the channels perfectly, including several I couldn't even tune in before. Up to 138 odd channels now and it's all working perfectly. Signal quality is much better and occassionally the picture breaks up during bad weather but it;s only for a split second and miles better than the rubbish outdoor aerial that could barely manage the main channels and would often go dead for minutes.

I bought the One4All SV9395 as have had good experience with One4All kit previously. Works great and very happy with the results. Am based in Esher area.

Knowing the Esher area fairly well having worked from Tolworth, I suspect your 'old' outdoor aerial was faulty or the cabling from it to the TV set was. The signals from Crystal Palace should be received perfectly well by a good aerial system, so I would advise having a contractor examine your outdoor system and correct the faults found. An indoor aerial is not guaranteed to give reliable results.

Alex : Hi Alex in Iver. Are you sure your Freeview receiver or box can decode HD (high definition) signals? I ask because COM7 is an HD multiplex rather than a standard definition (SD) multiplex. Standard definition (SD) receivers will not list HD multiplexes or channels on them when you carry out a service search or retune even if you do a manual tune, because they can't decode HD. You can purchase an HD set-top box for 43 online. I checked myself just the other day when my Freeview HD receiver failed: it simply connects via the HDMI connection to your tv set! Hope this helps, Richard, 11:18, Thursday 2nd June 2016, Norwich.

Hi MikeP,

I already connected directly to the aerial from the roof (it runs to a junction box inside the house) and although the picture is perfect there when I tested on the day, it still doesn't pick up half a dozen of the channels. I think the missing channels is because the aerial can't pick them up (I've never been able to tune them in properly) and either needs replacing for a wideband one or is not pointing in the right direction, perhaps because of bad weather knocking them askew. The picture dropping for channels I can receive does point to an internal cable problem but it's so intermittant and erratic that I've not the time or enthusiasm to spend hours trying to figure out what it is. The internal aerial works so much more reliably than the outdoor one with a much higher signal quality that there's no point trying to fix the outdoor one.

When you mention a 'junction box' do you mean an active splitter, a passive splitter or just a join between three or more coaxial cables?

There may be faulty connections inside a 'junction box' and you should double check all joints and connectors are fitted proper. If you are using a passive splitter, with no power supply needed, are all the output cables connected to a TV set? If not, an unconnected cable can give rise to frequency selective reflections within the cable and/or impedence mismatch which can cause you type of problem. Aerials must be connected to a 75 Ohm load, adding a passive splitter with an unconnected cable will change that dramatically! So check that there are no breaks in any of the cables too.

Any aerial for Crystal Palace must be either a Group A type (but not a wide band one, they will not help you) or else a log-periodic (which are wide band coverage) and all with the rods horizontal.

Hi MikeP,

I mean an active splitter. The aerial runs first to an amplified signal booster (goes from 0 to 20db but changing attentuation makes no difference though) and then from there to a powered active splitter. The splitter is used to feed an aerial connection to several rooms.

I've connected a TV direct to the aerial in three places; before it goes to the booster, after the booster and before the splitter and then finally, directly after one of the splitters. There are still half a dozen channels missing and same results so I don't think it's that.

The wiring was all done professionally but was a long time ago. What I don't get is that the channels will be fine one day (although still a bunch missing - channel 33) and then other times a multiplex will be completely screwed although it always seems to be the same set of multiplexes (channels 22 and 30).

With the indoor aerial, everything works all the time with only very minor interference.
