[TowerTalk] Common Mode Choke Locations

[john at kk9a.com]

The only location where I use a choke is at the antenna feed point.

The questions:

I realize that the bonding and lightning ground system isn't an RF 
ground, but I wonder if it influences the location(s) of common mode chokes?

I -think- a CM choke is appropriate at the antenna feedpoint, despite 
the bonding setup. Is that true?

Is an additional CM choke appropriate near the bottom of the tower? On 
which side of the bonding at the bottom of the tower?

Is an additional CM choke appropriate before the lightning arrestor? Or 
between the lightning arrestor and the equipment?
