Paul,
There is some stray coupling between ANT1 and ANT2, but no direct path.
The unused antenna is not grounded. One reason is that it can be used
to feed the subRX AUX ANT input when using diversity.

Hi all,
When messing around today with antennas, I had my aerial connected
only to
Ant 1 and discovered that when selected, Ant 2 was capable of
receiving
signals with no antenna connected to it, albeit at a much reduced
signal. I would have thought the unused
port would have been earthed out??
