Exactly why "US" wireless folks dont use flat copper strap. To difficult to
get a good mechanical connection!
It is fine in a HIGH RF environment. (25+ kW lower on AM frequencies).
If you can do some looking on the internet on in catalogs that specialize
in broadcast products, you will find a device and perhaps duplicate it.
73 and good luck!

Subject: [TowerTalk] ground strap to ground rod
|
| In my never ending attempt to provide the best grounding system I was able
| to pick up some pretty think, wide copper strips from a local sheet metal
| company.
| It was scraps left over from making a copper roof on a bay window.
|
| I took a couple of ground rods and with my saw and a vise cut a slot
| lengthwise at the top of the rod.
| I made up a jig to hold the rod and guide the saw.
| The saw blade was a close match for the copper thickness.
| I then drilled three holes through the slotted ground rod.
| After installation of the rods, I slid the copper in the slot, drilled
| through the copper and used small brass screws, washers and nuts.
|
| It sure seemed like a good mechanical connection.
| Anybody see any problem with this?
