Will cordless phones purchased in U.K. work in U.S?

Question

There are several cordless phones offered in the U.K. that have external antennas to boost signal strength. Will they work in the USA and would they be legal? Why is the USA lagging behind in offering these phones to the public?

Answer 1

you sound like you are referring to DECT phones... we have DECT phones in the US, but the US phones are 1.9Ghz, the UK phones are 1.8Ghz... they are not compatible...

Answer 2

No. The mains power is different (110 vs 220), the operating frequency is different, and the phone interface circuit is different.
