Actually this is not true. A non-shunt fed vertical
(i.e. ungrounded) only needs a few pf to ground to
initiate re-radiation. only one foot of coax connected
to the vertical will cause it to make it mess up other
local RX antennas. A relay opening the vertical
element to any matching components or coax can stop
the re-radiation. I'm not sure how to make it go away
with a shunt fed arrangement.
