Christopher Sercombe: I'm surprised you're using a loft aerial. I can see you have a rooftop aerial. Indeed, I looked closer at the series of Street View photos and saw that both you and your neighbour had your aerials replaced some time between May 2009 and June 2014, when the first and second photos of the road passing your house were taken. May I ask why you are not using your rooftop aerial?

I was thinking about your neighbour and that if you were having difficulty with reception via your rooftop aerial then your neighbour may be, as his/her aerial is closer to the tree.

Having looked a little along your road and nearby streets, I can see there are a number of trees. I would have thought the council must have a plan on maintaining them and wonder why the one near you is not being maintained. Indeed, in May 2009 it was much smaller than it is now, albeit that even then the top of the canopy was above your apex.

Noting you have Wiltshire Council as a unitary authority and Trowbridge Town Council at parish level, it begs the question as to which council is responsible for it. If you haven't already done so I would raise the matter with elected councillors of your wards at both levels.

Engaging with the department responsible for the environment, one is seeking to have something done. It is civil servants you are dealing with who follow procedures. By contrast, elected members are there to represent their constituents (or supposedly at least), and they may be able to exert influence in the necessary place to get a result.

Potential damage to building foundations is one such issue, and of course your neighbour has it overhanging onto his/her property. There is also the aesthetics of the overgrown ground around it. I guess having put the railings there then the council stopped coming along to cut the grass.

Until Thursday my Wife was able to get TXT on BBC1 & BBC2 to keep herself up-to-date on News & Sport. Yesterday & today this is not available.

Has this Service been lost as one of the upcoming Budget Cuts?

Hi Bruce. The service hasn't been cut, it is still working.
Mendip has been on Planned Engineering for a few weeks, whilst we've no idea of the exact work that has been done, PSB1 appears to have been on reduced power or the Reserve Antenna this week and it's possible there may have brief interruptions to the service but not that I've noticed.
I've used it during the last couple of days and it was working earlier and just now.

Do check obvious things such as your aerial still pointing correctly, check all your accessible coax connections for corrosion or water and check the downlead is not flapping in the wind.
And of course check you are still tuned to Mendip PSB1 on UHF C32.

Is anyone still having problems with channels breaking up? Just wonder if the transmitter is still on reduced power.

You haven't said which channels you are having breakup on!

Whilst it's not listed for Planned Engineering, we know the lists aren't always 100% however nothing has changed over the Christmas period which might simply mean no-one is there actually doing anything but I'm not convinced that it's necessarily running as normal!
Whilst I'm not getting any pixellation, I'm not getting my usual signal strengths on PSB1, ArqA and SDN.
I'm not sure if that's due to reduced power, reserve antenna, or something else!
I am however getting 100% Quality on all of them!
