Maximum output is 27.5kw from the 25kw transmitter pushing it to its limits.
They are using 8kw output to get 4kw radiated, i.e half the output power so there's some attenuation going on from the transmitter to the omindirectional antenna.
The solar meter panel shows between 10 and 12kw output to fully power 648 at 4kw though.
Was similar when they had the 2.5kw transmitter, they needed most of that output to get the effective radiated power.
6db does give double the coverage area and needs 4 times radiated power, inverse square law I think is the term.. If you need 8kw output to get 4kw radiated I don't see how 16kw output gets 16kw radiated power, should be less though I don't know if you increase the output power the radiated power would always halve.

Yes Roger already worked that out!
Also, it is mentioned in the detail of the application. Previous Message
The increase from 1Kw to 4Kw radiated was reported at the time as a 6dB gain.
So, I assume another 6dB gain would take the 4Kw to 16Kw, would that be right? Previous Message
Just noticed that myself on Digital Spy.
It says at first ""We request a 6dB increase from our current 4kw. "
Reading through not clear to me whether the 16kw is a request for output power or radiated power given they mention currently using 8kw output for 4kw radiated
It does say that Ofcom will determine the power needed for the desired extension area given. Previous Message
See this Ofcom link for Caroline's application for more power.https://www.ofcom.org.uk/__data/assets/pdf_file/0026/256913/Radio-Caroline-coverage-extension-request.pdf
