The symbol shows the location of the Rowridge (Isle Of Wight, England) transmitter which serves 620,000 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 Rowridge (Isle Of Wight, England) mast?

MikeB: Thanks Mike. An interesting observation. I immediately wonder why though? I'm aware that there is some current passing through the aerial - but on the whole it is an passive device - so unless it has become damaged in some way [and we *can* still receive BBC mux] why would the aerial be the component at fault ?
Hmm... thinks... current driven out of one or both of the devices [TV/ PVR] ...could one of them be loading the current too much and the signal reception "locked up" , err , read, can't read that signal because the driven current is somehow locking it or blocking it [not technical terms, I'm not a hardware engineer but have a bit of an awareness at that level].

David Fox: Your overthinking it....
Rowridge has no reported problems, so its not the transmitter. Nor is it one of your boxes, since they both have the same problem, which is that your missing (at the least) the PSB2 Mux.
Your TV is linked by a thin coax wire up to the aerial. Its subject to extremes of heat, mositure, wind, etc. And of course it degrades, like anything else. Its also possible that it was put in my someone who bodged the job, used the cheapest cable, etc.
It could be a frayed or loose wire, moisture or corrosion. If you've an amp, it could be a failing power supply. In one recent case, it turned out to be a dodgy fly lead.
Whatever it is, it will have nothing to do with the current, etc, but almost certainly everything to do with a simple break somewhere along the chain.

Vanessa, it sounds as though water is getting into the aerial system somewhere. Possibly the downlead. Could be a number of things, but from your description that sounds most likely. This can affect only certain groups.

Bob.
Thanks. I thought that too, but I have two tvs fed from the same downlead. One fine (the cheap one), one not. Unless the internal lead went wrong. But once the bad weather cleared, it all got better. Plus, it was ok in daylight hours, but dropped off after dark. I am on the edge of good reception where I am, admittedly. This time it was my Dad's signal that went, a couple of miles down the road. Mine is ok. . I continue to investigate - it's an intriguing little mystery????

Vanessa: It sound exactly like moisture in the system. Since one tv is fine, the fault is on the other one, which at least means you can narrow the search for the problem.
Could you give us a postcode, because it would help to find out if your on the edge of the signal range. Personally, I think your fine - my parents live in Poole, so I know the area where you live, and its not only about the same distance, but your predicted to get a better signal from the transmitter than they are!

MikeB: Thank Mike - you are absolutely right; after a bit of investigation , it turned out to be the amplifier in the loft that has "failed" in some way - not just the fuse in the plug :-) - I've bypassed it and returned and all is well. To be honest I forgot we'd got an ampliflier - we've only had to use it a couple of times - when we've moved the TV between rooms. anyway, I witter on, problem found.

Hi,
I have good redemption from a small loft aerial in my bungalow on all Freeview channels but cannot get BBC4 HD. What kind of aerial do I need to get this channel as well as the others?
Thanks

Chris Shaw: To get BBC Four HD your aerial will need to be horizontal rather than vertical. So if you switched to vertical polarisation it will need changing back again as the new HD muxes aren't VP..
Judging by the terrain plot you may have clear line-of-sight at 22.6 miles. A loft aerial may do. It's not that you need a different type of aerial per se but that the transmission power is lower, although at just over 24kW it should be ample to serve you.
Can you not put the aerial outside or try moving it in the loft? See whether any trees might be in the way.
Also, try going to the manual tuning part of your receiver and enter/select UHF channel 31 but don't press the button to scan/add channels immediately. Instead wait and see whether it gives you any indication as to strength and quality.

Thanks, Dave Lindsay.
My spell checker turned 'reception' to 'redemption' - I have good reception on all channels but I think I am beyond redemption!
Our current aerial is tiny. About 30cms long with 20 vertical elements of different lengths and no reflector. The signal strength on nearly all channels and certainly the main ones is 8-10 and the signal quality is 10, as shown by the tuner.
Is it possible to get an aerial that does horizontal and vertical at the same time?
Cheers
