If a product was available that offered these features with the same

Something that should not be overlooked is acoustic noise generated by an
antenna matching unit (ATU) if it is to be used outside, relays clattering
away at 2am could upset the neighbours! Far better is the 'purr' of a motor
driven capacitor used in an 'old fashioned' link coupled matching unit,
nevertheless I have mine in a soundproofed box.
My wish is that the designers of commercial tuners would allow tuning to be
achieved with milliwatts of RF rather than watts, which is feasible. IMHO
tuning with RF levels above a few milliwatts erp is anti-social in terms of
QRM.
