I believe it was quite common for UK airfields to have both a 10cm and 50cm radar concurrently. Jersey and Bristol spring to mind.
Glasgow had 2 x S264s when I was there in the '70s; no 10 cm.
Many RAF airfields relied on CADF to 'vector' the aircraft overhead and let down until they could be seen on either ACR 7 (424) or PAR to commence a talkdown, both of these being 3 cm so still not 10cm, the problem being 3cm radars are more affected by weather clutter than 10cm so need some sort of weather suppression. The RAF's latest PAR is processed which effectively suppresses all but the very heaviest rainfall. They can also display SSR.
