using them for a low power cross-band vhf-uhf repeater system, working satisfactory, able to cover 3-4,kms in suburban location, connecting dual-band radios when they 8kms apart on opposite edges of coverage pattern. technically it is possible as 1watt radios give about half the coverage of a 10watt radios in the same location. thanks
