Buz Earth Bar
This is a typical arrangement of equipment bonding. A thick piece of 2X2 1/4 inch aluminium angle was fixed under the stations rear desk top, as shown. Double nuts and bolts secures each item to the buzz bar, with a short semi flexible one piece aluminium strap. Double fixing these straps prevents rotation which eventually would have loosened.

Cable Tray
An additional plastic cable tray was laid along the rear operating desk edge. This carries all the screened equipment inter wiring, and makes for a neat and tidy installation. Center right is the LPF bolted to to the RF earth strip.
