I have a large, thick plate of aluminum and to it I have bolted about a dozen
Alpha Delta switches (all with a gas discharge tube) . Every antenna line is
connected and every radio as well, it allows me to easily connect any source to
any receiver, transceiver, etc.
I will have my cables grounded at the top of the tower(s) as well as they enter
my shack. Nevertheless I want to make certain that this switch board is
effectively connected to my SPG.
I want to make this connection with a wide copper strap. In the past I used
brass plates between the copper strap and the aluminum plate and used stainless
steel bolts to hold it tight. I also used one of the greases (don't remember
which one) to keep moisture/air out of the areas of contact.
Is this right?
Is there a better way?
Thanks!
