OK, have been monitoring reception over the past few weeks since having my new TM F3/5 (mid March 2014). As you know, this gives a % point reading which is more revealing than my Humax - which is limited to a % range.
The frequencies that I have been monitoring are on both 2e + 2f and are of interest to me (the channels we watch) so provide a good selection of 'normal' UK TV (BBC/ITV/CH4, CH5 etc) on both H and V.
The attached reception .jpg gives the latest set of results that I have, taken on Tuesday 15 April. I only uploaded the one set of data because, to be honest, not much has changed in terms of reception during the past 5 weeks. All readings that I take are on clear sunny days/clear nights with no cloud. The slightest hint of weather (rain) and I loose the lot. Individual readings in the % column may show more than one set of digits (e.g. 61/62/63), this is because the TM F3/5 data 'flicks' from the lowest to highest %. So I record them all. In general, anything at or below 61% on a SD channel gives a degree of pixelation but when it is 62% or above things are fine. For HD channels I need 64% or more to avoid pixelation, so its a close thing.
As you can see, 2e is the problem child but apart from Ch4 and BBC2 UK, I do get a reasonable set of channels to watch most of the time and there is a work-around for BBC2, I switch to BBC2 NI when/if the programmes I want is available. Best reception appears to be in the very early hours of the day.
I know that this is not a truly 'scientific' set of data as it simply relies on the readings from my TM, and that can obviously vary from one machine to another, but it does demonstrate how close to the edge things are and any small % point gain can make the difference between picture/no picture (hence my earlier obsession with receivers and LNB's). I will maintain a weekly check to see how things go throughout the year.
