However with a TVonics MD-252 freeview box there is no reception of any digital channels.
As I understand it currently Analogue Ch5 is on C39 @ 10kW (-20dB), and the nearest digital signal is MuxC on C40 @ 20kW (-17dB).
Is this correct? - if so I'm confused why the TVonics box can't see at least MuxC as I would have thought that the 3dB difference in power between would more than compensate for the roll-off on a Group-A aerial between C39 & C40.

I have a loft mounted Group-A aerial pointing directly at Sandy Heath Tx (aligned with a compass) from Cambridge, distance is 30km.
Currently the analogue TV receives all the main channels, including Channel 5, with excellent picture quality.
