Topbanders,

During the winter, an icy pine branch saw fit to down my 160 inverted-L and
so I've begun planning a replacement. As we're allegedly headed into the
spring, and as it is unlikely I'll get to raise a tower with other work at
the new QTH still going on, I'm planning on something easy for all band use.

My plan is a 200' doublet (100' each side) about 100' high fed with ladder
line. At the base will be a legal limit remote autotuner and thereafter
hardline to the shack. That setup should handle 10-80. On 160, I'd like to
short the ladder line together and feed as a T against the existing radial
field.

I know some of you are using similar setups, but are any of you doing it
remotely as opposed to a "knife switch" in the shack? Any experience with a
high power switching setup (relay type, circuit, mechanics, etc.)?

73,
Mike N1TA
