Topband: Where to ground the Beverage feedline?

[Martin]

Topbanders,
please comment on this :
The feedline of a beverage is buried all the way from the feedpoint to 
the shack. There it goes up vertically about 5meters, enters the shack 
side by side with other feedlines and is- after about another 5meters  - 
connected to the radio .
The cable is fitted with a common mode choke near the radio.

Where should i ground the feedline? Is it a good idea to ground it where 
it comes off of the soil? Should it ( additionally) be grounded at the 
radio? Should i install another common mode choke at the feedpoint?

All comments welcome.
