Dear Robin,
Since you're UK-based, it would do no good to suggest US
suppliers...
However, UK-based television stations, when they do an annual POP
or xmtr alignment, will rent a portable DL from somewhere in the UK.
These devices are on trailers and rent for the day, week, etcetera.
Check with a broadcaster on your island, and check into the internet
under Broadcast Equipment Rentals.
Cheerx,
Hal Mandel
