Much snippage...

Only if you feed the 1/2 in the low impedance point, which is halfway in
the
middel. Since this is impractical on a boat, feed it at the endpoint. But
at
the endpoint of a 1/2 wave, the impedance is very high so you need the
least
capacitance you can get at the antenna feedpoint. So GT15 is ok, but keep
it
1" away from any grounded or other conductive area (like strapping the
GTO15
to the uninsulated lower part of the backstay with tie-raps... BAD
PRACTICE).

Is the 1" just a rule of thumb or is there some engineering calculations to
support this distance? I see many sailboats with 1" varnished wooden dowels
or even plastic hair curlers with cable ties used to keep the GTO15 off the
uninsulated backstay wire. I have a feeling wider spacing would be even
better.Comments please.
