Comrades,
what I was wondering was whether an analyzer would help me locate and
tune an antenna on my boat. I was hoping to find out whether it would
"see" the capacitance and other effects of several of the large metal
structures above deck. I was hoping that I would be able to move the
antenna around, maybe tip it a bit, adjust its ground connections and
try a lot of things and have some hint of progress show up on the
analyzer. I was hoping I would be able to see whether grounding these
other structures was worthwhile or indifferent. I am not likely to
have to deal with strong adjacent signals nor other structures. All
"near-fiield" effects will be caused by a large radar arch (aluminum),
an aluminum jib crane (dinghy lift) and the other antennas. As always,
I'm astonished at the knowledge available on this reflector and am
appreciative of the help I'm getting.
