Consider TV coverage, UHF channels versus VHF channels. The difference
in coverage is small..

In the good old days, increasing the frequency often meant decreasing
equipment performance. Solutions have now been found to many UHF
equipment problems.

Not sure about the TV stations but I was thinking they can run more ERP than
the VHF stations.

In the 'good old days' it was difficult to build a receiver that was as
sensitive at 440 as it was at 150 mhz and power was harder to generate also.
With solid state there is very little differance in the devices sensitivity
up to atleast 1ghz and maybe higher than it is at 30 mhz. Power in the
range of 100 watts is easy in the solid state units also now.
For the last few years it seems that many ham rigs have about 35 watts on
440 and 50 watts on 2 meters. Mainly in solid state gain blocks. Not that
much differance .
