Me neither. Nor on caravans (still fitted as cheaper).But I simply can't see why anyone would use an omnidirectional aerial for TV in a fixed location?
Still do have Welsh and English TV. Also Scottish and Irish TV (in two flavours UK and RTE from the EU <ducks>).OK before digital when we had Welsh and English TV, but today no.
The proper way is two antennas and frequency-selective filtered combiners... but that's not so easy post the 700 MHz clearance. In NI they provide RTE in some places from an almost co-located site so within a single antenna's acceptance angle.
As for TV on the move -- there were tests of that with DVB-H (handheld) in the early 2000s that failed to become mainstream. But it'll be with us any time now via 5G mobile phone signals.
