FW: Srike rail/tank circuit shield grounding

It is my understanding that the strike rail and shield for the tank
circuit are to be connected to RF ground.  If this is indeed the case,
if using a counterpoise are the before mentioned still connected to the
counterpoise?

Also, although wanting to keep the distance from the tank circuit to the
primary coil short, how long can this realistically be on a small 6 kV
30 mA coil.  On the same coil if one decided to mount the tank circuit
beneith the primary coil what sort of clearance is required and would a
fan motor on the spark gap be affected?

Thanks for your help.

Chris.
