The symbol shows the location of the Caradon Hill (Cornwall, England) transmitter which serves 180,000 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 Caradon Hill (Cornwall, England) mast?

I regularly experience poor quality reception which has been ongoing for months. I'm going to upgrade my roof mounted aerial.
Can you tell me if it would be best to go for a gorup A or wideband aerial for Caradon Hill? (Loaction Holsworthy).

Dave Atkins.Holsworthy,EX22 6JB.As Caradon Hill is an all group A transmitter located almost 20 miles from your abode to mast,your best bet is to go for a group A (red tipped) aerial or a group K (grey tipped) semi-wideband aerial but only if you decide not to persue the group A aerial itself.
However a group W wideband aerial (tipped black) on the other hand is by and large rather useless on an all group A mast such as Caradon Hill in a poor/marginal reception area.If you decide to buy a new group A (preferred) or group K aerial (as a last resort),then simultaneously buy new superior copper-copper black coloured (sometimes darkest navy blue it appears) co-ax cable,and importantly new brass co-ax aerial plugs,not alloy or worse plastic plugs as they're useless.
I would strongly look up the ATV Aerials and Television of Sheffield website for proper advice in buying new aerial and accessories and belive me they are the No1 in my honest opinion in the UK today.Forget the rest ATV of Sheffield are the best.

Does the whole of Bodmin get its TV from Caradon Hill, or are there any repeaters as well? I have been asked whether it would be feasible to broadcast a local TV service for the town and this would only be commercially viable if a single transmitter site (possibly not at CaradonHill but in line with it) would do the job.

Black Torrington.
We receive our Freeview from Caradon Hill... or we would normally. For the last 3 days we, and a number of our neighbors have experienced extremely weak signal or no signal what-so-ever. Our living room TV is rigged up to Freesat, so we have been able to watch one TV at least. There was a mention on a Spotlight weather report on Saturday afternoon of strange atmospherics due to the high pressure sat over the country... though there has been little other mention beyond that.
This website has been saying that Caradon Hill is working, though I cannot help but wonder if their diagnostic/monitoring equipment may be on the blink.
On behalf of my neighbors, myself and anyone suffering from similar issues, I request that an engineer perform a detailed manual inspection of the transmitter, or that someone be sent out with the necessary tech to determine if we have some kind of localised interference here in Black Torrington... who knows, perhaps some inconsiderate so-and-so is playing around with field-generators nearby, lol.

Under atmospheric high-pressure, distant transmissions (from France or the UK) can break through and interefere with the signal you want - Caradon in this instance. If things are back to normal now we have a low, this would be the most likely explanation. If the problem persisits, you might wish to check whether you can get a signal from Huntshaw Cross on a CD aerial.

Dave Fletcher: Mark's advice is sound. However, you may find that a log-periodic aerial serves you well. I receive Caradon
at 50miles on a log from ATV :-) If Caradon is weak at your location, the group A aerial recommended by Mark would be best, but, being longer, needs a sturdy mount. A log is robust and wideband and normally should give you a good signal at 20miles. It would also allow you to try other transmitters in the Southwest if you were interested in experimenting.

My signal comes from Caradon Hill. I have a one year old TV with integrated Freeview. The aerial is in my attic, not exposed to the elements. I have never had a reception problem. But since the past three days approximately, I have had "no signal" on all the ArqA multiplex channels (aerial group C24). I tried doing a Freeview reset, and that resulted in all the ArqA channels disappearing from the EPG. I do not have a digibox, VCR, PVR or games console or any other analogue video equipment. Also, we do have any new electric equipment that we have plugged in in the past few days. I tried to manually tune in C24, but my TV digital setup showed on C24 signal quality of 0 and signal strength ranging between 0 and 7 out of 100, so the TV could or would not tune in C24. Any ideas?

Paul: At 5 miles away from the transmitter and with only a minor obstruction being seen on the signal path (about 0.25 mls from you) is liable to suggest that some problem "might" exist with your aerial system albeit I do acknowledge the fact of you having said that its located in the loft.
As you haven't actually mentioned what the other channels are indicating, what you should do is go into the tuning menu / manual tune and enter Ch21 (ITV3 etc) but do NOT press search or scan, because on practically all devices with a manual tune facility after you have entered the channel number the level of the signal will be seen, make a note of whatever it is then carry out exactly the same procedure again but this time enter Ch27 (Film 4 etc), once again noting the level, then finally repeat as before but use Ch24 then compare this with the levels that's been seen across the other two commercial mux channels, and which by the way all radiate on 50Kw compared to the PSB's on 100Kw.
Its quite common for levels to change over the year through atmospheric reasons, but not with the magnitude such as you are reporting.
It might transpire that you will require to move your aerial about 12" or so either side of where its presently positioned, this done while leaving your TV on the manual tuning procedure as mentioned as its tuner acts like a signal meter when used that way, but further advice is dependant on the results of your test.
By the way, work was going on at Carradon Hill yesterday connected to DAB radio but not according to info the TV services.
