Hello,
I am used to having a few days of poor reception periodically over a year. I live at the bottom of a valley and reception can, on occasion, be difficult. I use the Mevagissey repeater for terrestrial TV. However, this year and specifically in the last 6 months, reception has been consistently very poor. Interestingly the BBC channels are first to break up and ITV channels the last to fail if indeed they fail at all.
I have had a full review of my aerial installation by a professional installer and they could find no problem with the equipment and had no better or more up to date aerial to offer that would improve things. Coming from a technical background I can only conclude that since nothing has changed at my end and that the equipment I have is operating correctly either there is a new obstruction in the path of my signal or a change at the transmitter. Weather conditions do have some affect. High pressure tends to cause me problems, but once they clear I used to get back to normal reception. Now, reception is almost always poor. BBC is impossible to tune. I have installed a satellite dish as an interim solution, but would very much like to resolve my aerial reception issue. My problem is further enhanced by a poor broadband speed and so on demand television is not a practical solution. Looking forward to any assistance,
Kind regards,

David Sargeant:

Can't find any reported faults either by Freeview or the BBC, and the Mevagissey transmitter isn't currently listed for Planned Engineering.

There has been a lot of "Tropospheric Ducting" accompanying High Pressure over recent months, most recently it did affect quite a few areas of Devon and Cornwall as well as other parts of the UK from time to time. However it is currently totally clear according to current predictions.

Without a full postcode, we can't look at what your predicted reception might be, or what even the typical Line-of-Sight to the transmitter might be. That in any case would not take account of any new buildings or trees etc on the L-O-S.
Do you have any trees near you that have grown larger and maybe on the LOS?

Whilst you've had your aerial checked, have you changed you installation in any way?
Also check any wall-plates, coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them.

See what signal strengths and quality you are getting for the multiplexes (groups of channels) shown in your TV's tuning section.
The UHF channels for Mevagisey are C46, C43, C40 in the order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3.
Are the BBC ones poorer than D3&4?

Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
