Now you can use 5 antennas on your 1 all band HF radio without having to run a bunch of coax out the shack. The RCS8V remote coax switch is a relay driven box that mounts outside on your mast or tower, and allows 1 coax input feedline to connect to 5 different coax feedlines at the top of your tower, handles 4000 PEP 16010m, and 1000 watts above 30 mhz.
