Jackie Webb: Sky News is on the COM5 multiplex which moved to a new frequency a couple of months ago, which is outside the range that a Group C/D aerial (which you are likely to be using for Mendip) was designed to receive. If you don't have satellite or cable you may be eligible to have a replacement wideband aerial fitted free of charge, which can be arranged by contacting the Freeview Advice Line (see link below).

SJ Dunnett: In addition to what has already been said by StevensOnln1, you heed a high(ish) gain wideband (group T) or log periodic (log36) aerial. You have line of sight to the transmitter so should not have any problems. You should not need anything as big and clumsy as a Tri-beam or a 22 element. Unless you are planning to install the aerial yourself, I would seek the advice of a CAI registered aerial installer.
Jackie Webb: A lot will depend on your location (need your postcode to see what predicted reception is for your location) and how old your current aerial is. After Ch.5 analogue (UHF35) started transmitting from Mendip (long before digital), there were some "enhanced" C/D group aerials produced which weren't too bad at the 30's UHF channel range. It would be a good idea to check that you are actually tuned to the correct UHF channel for COM5. See my post Tuesday, 6 March 2018 3:55 PM for detail. Check your TV manual for how to do this & manual tuning.

Hello,
Since the change in frequencies I have been unable to receive Sky News and Dave.
I have installed what I thought was an upgraded wide band aerial Screwfix high gain 48 element code30515 but no better. I note both are on channel 36 ARQA.
I also have a Tevion 14dB amp in circuit.
Can you advise further please. Aerial is on roof. Thought of higher pole as on bungalow.

I'm confused. Recently I changed my tv aerial and started to receive signals from Mendip (before that I was tuned in to Hannington, all legit because I live on the border between these two transmitters). I did a complete retune and now get a bunch of channels with BBC1 West (etc) on channel 49, with good reception. So far so good. But your table shows (I think!) that on 31 March this year BBC1 (etc) moved to Channel 32. I get nothing at all on Channel 32. What gives, please?

Just purchased a brand new up to date TV and had a new K aerial installed and guess what from my location here in Somerset I still cannot get consistent reception of all the HD channels, it has now proved beyond doubt that digital reception on the Mendip transmitter is worse than useless in the Yeovil area. We sit on the crosswires of Mendip, Stockton Hill and Rowridge and none of them give us a decent service. If ever a place needed a relay it's here. I think it's time to pack it all in and go back to radio.

Sorry that should be Stockland Hill and not Stockton!

Bill McDonald: I can see that parts of Yeovil seem to be a bit of a no-go area, but obviously it depends on where you are, your postcode will enable a better prediction of likely reception.
Is it only the HD channels you are having a problem with - if so which mux? BBCB, COM7 or 8?
Another possibility you might consider, does your new TV have a built-in Satellite tuner?

A G Hearn: Is it only Sky News and Dave you are having a problem with on the ARQA/COM5 mux - ie. are you getting - Pick (11), Sony Movie Channel (32), Movies4Men (48)? If you are getting these other channels, then it's possible that retuning hasn't put all the channels in the correct location - you might find them in the 800's. In which case I would suggest a full reset - see your TV manual if need be, but the usual method is the do a full automatic scan with the aerial unplugged.
You may get some help from the Freeview reset procedure link (in the top area of the comment box here).
However there are other possible reasons and your postcode would help to look at the likely reception in your location. You may be in a difficult spot, there may be local interference, you may possibly now have too much signal.

Bill McDonald: put your postcode into the site, and it should tell you signal you should get at your location. If it's rubbish because of geography etc, just get Freesat.
