The questions about DSO and grouped aerials are important. If your bod
stuck up a wideband one and the channels broadcast by your transmitter
are in the newly extended group B (low) then you have lost 4-6dB of
precious signal just like that cos wideband aerials aren't optimised
like grouped ones and favour the high end. (A wideband aerial will have
a black plug in the back of the aerial extrusion.)

Yup grouped aerials are particularly important for group A and B
transmitters - especially in difficult locations.

If you're pre-DSO then you'll be seeing a whacking improvement in signal
power when DSO happens in your area.

Indeed - we saw a rise of 19db overnight on the muxes that have just
gone full power.
