Want to know which transmitters will carry extra Freeview HD?

Details of the new Freeview HD transmitters to come on air next year

Details of the new Freeview HD transmitters to come on air next
published on UK Free TV

I am working on integrating this information into UK Free TV. Note there are a number of sites with restricted radiation patterns. This information may take a couple of days to generate coverage maps for.

I have used the "Nominal ERPs" (the power levels most likely to be employed in practice by the licensee).

Taken from Ofcom - Award of the 600 MHz spectrum band - it's bad news for The Wrekin and Sudbury, but good news for:

The reason for the low power levels is in part because Arqiva are going to reuse old assets as far as possible. The nominal ERPs match their latest Reference Offer. They're based on whatever the available antennas can handle, and what power the available transmitters can provide.

So, for example, Crystal Palace C33 will be from the PSB antenna at the top of the mast, using the transmitter previously used for pre-switchover Mux 2, while C35 will come from the COM antenna just below, and use the pre-DSO Mux B transmitter. Meanwhile, the former backup transmitters from Croydon will be travelling to Winter Hill, where they will drive the pre-switchover digital array, which has to be rotated so its null points in a different direction.….pdf for the details.

As far as which sites have been selected: "the list of 30 sites has been chosen based on indicative population coverage and ease of implementation." You have to remember just how many people the top few transmitters serve. The whole point of this is to get a cheap service serving as many people as is feasible, as soon as possible.

If it becomes apparent that existing frequency allocations to mobile communications are sufficient for the foreseeable future, will COMs 7&8 be extended to cover other transmitters, with existing transmitters being given additional power?

This question is really curiosity. At the moment everyone seems to worship the mobile phone and mobile data. What if the growth in demand ends and the level of demand plateaus at a quantity that can be served by existing available bandwidth, either as is or by using new technology to utilize it more efficiently? Just because demand for mobile communications seems to have grown exponentially up until now, surely that doesn't mean it will necessarily continue so?

How likely are these muxes to come to other transmitters and for what (technical) reason are some main transmitters left out? In my case I'm served by Knockmore, which according to this site has both C33 and C34 free, so why aren't they being used to carry these muxes? Thankfully we have a dish set up in addition to the aerial, so we should be able to get the new channels that way. We won't however be able to use them on our YouView DVR.

I see that ofcom are saying that Crystal Palace and Sutton Coldfield could be broadcasting Com 7 by December this year.
Will Com 8 be broadcasting soon after?

Are there any HD channels available in Hereford area,and if so where are they transmitted from?

Johann Techman: Every transmitter in the UK carries 5 HD channels, so you should be able to pick them up assuming you have Freeview HD equipment.

If you mean the extra HD channels via the com7 multiplex, then go to, put your postcode and tick the "detailed view" box. Using a sample postcode of HR2 6PD you should be able to get it from Ridge Hill later this year.

Please could you advise if the sudbury transmitter will get the extra HD channels soon, i.e. BBC4 and BBC news HD etc as it seems a bit unfair that such a large population area i.e. Essex should be deprived of these extra channels.
I am very disappointed as I was expecting to receive them in summer 2014 at the latest!

sherise: Nope, not likely. The plan was drawn up for 30 full service transmitters only, and this didn't include Sudbury, Dover or Heathfield, to name but a few.
