For your particular installation I would suggest investing in some
decent coax. If I were you, I would use Times Microwave LMR 600 Ultra
Flex right from the shack, around the rotator and to the antennas. It
will hold up to the elements, is very low loss (less than HALF of
RG-213), and if you ever decide to run any power or do any weak signal
work on 6m, it will work FB for that too :-)

You can buy the cable and the special connectors for it from Texas
Towers. GL and VY 73, Lance
