The first thing was to saw the base off, carefully, and then drill a hole with a pin vise- just sufficient for the pin in the base of the aerial. I fixed the unit in place with rubber glue, in the event that I need to remove it in future, for maintenance.


The MK aerial has a rubber base, supposedly to allow a little flexing- units for Russian tanks are spring-loaded, I believe.
This is the German one.
