Well with bits dropping off your old aerial, it's a good job it was replaced, from a safety point of view even if your reception didn't appear to be affected.
You are very lucky because you are in a pretty good location where your predicted reception for COM7 is quite good, but what's more, you location is also giving some predicted reception from Storeton Wales, figures all in the green! I'd had a look at a random selection of postcodes elsewhere in your town and figures for COM7 were quite poor, none gave any prediction for Storeton, and the BBC didn't predict anything for COM7.
Let's be crystal clear, I was not saying that log periodics were no good for COM7, my remarks were to Peter Whitehead in the context of the poor predicted reception of COM7 in his location. His predicted "Served" figure is 4 - not just poor, very poor! compared to your figure 88. That's a huge difference for reliable reception.
Karl:
Whilst I haven't got your postcode, in your location at Cleveleys with that Antiference RX20, it's serving you well there. Those figures are pretty good. You've got plenty of gain from the aerial and with the amp and splitter, in a way I not surprised you needed the attenuator! The slight drop-off at C58/59 is no doubt due to it being a Group T, but even the lower strength figures on those local muxes is no problem to a good set, the key being the 100% quality.

Bob:
Have you had any luck? Propagation conditions should be a bit more stable now. Tell us a bit more about your installation, what aerials have you got? I'm guessing, but you don't have any amp/splitters?

Peter Whitehead:
I had meant to include this link to some gain curves as examples of how much extra gain you can get at the top of the band with a Yagi18WB compared to a log periodic. If it were a Log40 and you're in a good reception area, it would be quite good, but these aerials are no longer made.

Beacon Hill is a Group B aerial. But you are not in a very good area for Beacon Hill. If it's the COM multiplexes you are after, then you are going to need a high gain (14/15dB or so) to stand much of a chance of reliable reception.
I assume you know there's a relay transmitter 2km south of you which would of course give you reliable reception of the PSBs.
With an aerial pointed at Beacon Hill (horizontal polarisation) ~SSE bearing 161 degrees, you may/may not still get a signal off the Liverton relay (which is a Group A vertical polarisation but very low power) as it's close.
Note, you will not get as much gain with a Group T, K, or Wideband compared to a good quality Group B.
Also note, there's no COM7/8 at Beacon Hill or other local transmitters (COM8 has closed in any event).

Whoops, I did read "log" on the first reading of your previous post, but didn't reply until later and clearly read it too fast then! You are obviously in a good spot, even though I can't see your predicted figures (need postcode). Difficult to judge (from a distance) about how well an XB10A would do in a loft (you've got space I suppose) you've got plenty of extra gain, but attenuation from the roof etc. Loft aerials become much more of a black art, depending on what you've got in there (water tanks, metal flues, partitions walls, etc., lead flashing, solar panels and the likes outside! You really need a signal meter on site, especially for the two local muxes you currently get, the gain is dropping off quite rapidly at 21, and tailing off at 40, add the attenuation of the roof and etc.
Let's hope you don't need another replacement in the next two years ;)

I understand Freesports have pulled it from Freesat because apparently "it can't agree on commercial terms with the satellite TV provider."
It's obviously a bit of a mess because the channel is no longer listed in the header on the home page, but it's still mentioned in the FAQs ! Can't spot any explanation on their website.
Rxtv log has posted this -
"Most affected viewers have two options to restore access to FreeSports:
Live stream online via the FreeSports Player
Manually tuning their existing Freesat receiver although some devices, such as LG Smart TVs with in-built Freesat force viewers to choose between Freesat or a general unsorted list of free-to-air satellite channels.
The manual tuning parameters for FreeSports HD are:
Satellite: Astra 28.2
Frequency: 11426
Polarisation: Vertical
Symbol Rate: 29500
FEC: 8/9
Service ID: 52575
"
It's still available on Freeview at LCN64 now on COM7 UHF C55.

Karl:
You're doing quite well it seems. Both the Freeview and BBC predictors give COM7 as variable, with the Served figure being 57 from Freeview, not as good as Robert Lee (88). What is interesting though is that neither give a prediction for the Liverpool mux on C21 and of course the petal isn't beamed in your direction, so you might lose it with a loft aerial.

Keith Page:
Forces TV in on the COM7 multiplex which isn't broadcast from Sudbury. It's a temporary multiplex only broadcast from 25 main transmitters which will close by June 2022.
Unless Forces TV negotiate a deal with a multiplex operator to move to one of the other multiplexes, the situation won't change before then.

Whilst you would be best addressing your comment to ITV - details here - ITV3 the schedule is no doubt arranged by what is screened on ITV3 rather than the +1 channel.

Blimey, a bit of space there then, that looks like almost half the capacity!
