I don't have it in front of me at the moment, but if I remember my old ARRL,
(American Radio Relay League), Manual correctly, they should be mounted so that
one edge of the circular portion is down on the circuit board, so that the board
is at a tangent. If two are to be mounted in close proximity, then looking down
at the board, the two should be mounted tangentially to it, but forming a
capital, "T", with respect to each other, to minimize cross-talk. A lot of
these together, may require Mu metal shielding. Your mileage may vary, of
course.
