I sincerely hope the channel changes shown here for March are incorrect. Having invested in a new aerial and a freeview recorder box, it would appear that my aerial which is designed for the former group b and c will not get the main BBC and ITV channels which appear to be moving to a group A aerial.

I think it is a liberty to make people invest in new aerials to receive freeview and then a few years later change the channels used so that yet another aerial is required.
If the latest changes result in viewers being unable to watch their tv's because the broadcasting channels have been moved to a different aerial group, is there a body we can complain to?

In my case a wideband aerial was not good enough, I specifically needed one biased towards the muxes on channels 56, 58 and 60 which were weak. Now they propose to move the channels out of aerial group, to the opposite end of the available frequency bands, around channel 30!

nick horrex: Anyone who relies on their aerial for reception (i.e. doesn't have satellite or cable) will be eligible for a free replacement aerial if they loose any of the PSB1-3 or COM4-6 multiplexes as a result of the 700MHz clearance changes (provided the existing aerial is in good condition and not damaged etc). The link below gives details of the Freeview Advice Line who will assist anyone who finds they have channels missing following any frequency changes at their transmitter and will arrange a free of charge engineer visit if the missing channels cannot be restored by talking the viewer through a manual retune.

Michael Firth, Nick Horrex, et al:

That is why many contributors here have been advocating having a log-periodic aerial fitted if you need a change. They cover all the likely channels and predicted changes expected over the next few years. So having a grouped yagi design fitted will, in some cases, become outdated and potentially unable t provide satisfactory reception of all the wanted channels.

thank you, but log periodic is no use to me, not nearly enough gain.

Nick Horrex:

You can get log-periodic aerial of up to 56 elements with commensurate higher gain than those with fewer elements. I use a Log36 but my brother uses a Log48 as he is further away from the transmitter than me. Our uncle now uses a Log56 as he is even further away in a different part of the country. I must admit that such aerials a not easy to find though. However, a variable gain amplifier can resolve weaker reception as long as there is no local interference present.

Russ: Never. COM7 & COM8 are temporary multiplexes which are broadcast from 30 main transmitters covering around 70% of UK households and are expected to close somewhere between Summer 2020 and 2022. FreeSports is available on Freesat, along with almost every channel found on Freeview as well as numerous others.
