[TowerTalk] cooper ground strap to aluminum panel

[Kevin Shea]

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!
