Is R/S RG6 of "decent" quality for a receive only application (to a scanner)

It's fine. And I notice you keep saying "receive only." Loss is loss
whether transmitting or receiving. I've used RG-6 for Transmitting at
VHF with about 25 watts of power. RG-6 can easily handle that power,
and the fact that its characteristic impedance is 75 ohm matters
little.
