My grounding plan!
The best I could do given the location of the tower.

Valmont Microflect Panel - Installed between 2 studs 16" on center.
Feedlines entering shack via grommet ports.
2 6" copper flashing provides for ground connection path from SPGP on inside wall back to grounding field.
Valmont Microflect Panel with grommets installed. Copper Flashng is the ground coming from the SPGP inside. I used short pieces of coax to plug the unused holes. Plugs are available. These holes are now filled with new feedlines.
SPGP on inside wall installed over entrance ports from the outside. Polyphaser's installed for feelines, rotor, CATV and AC power.
Inside view looking down on the SPGP. Cables are coming though the Microflect panel and attach to Polyphaser protectors on the rear of the SPGP.

Nearly fully loaded SPGP -
Ethernet on left and CATV on right have been added.
Along with additional feedlines for dipoles and protectors for satellite antenna's
The compnents for grounding my coax at the top and bottom of the tower.
The components and tools used for coax grounding.
Making my own coax ground clamps from copper strapping
Homemade copper strap clamp. The clamp was formed by using the flat pliers and bending it around a twist drill bit of the same size as the coax with the sheath removed.
Sample clamp in place on a piece of coax. The ground lug can be flipped in either direction.
Sealant tape wrapped around finished clamp.
Electrical tape applied over sealant tape
Grounding clamps installed on all feedlines and attached to tower at top and bottom
Ground connections at the top of my tower
Bottom of tower bonding connections
Ground lugs attached to tower leg.
Copper strap is sandwiched between aluminum and Stainless stock with some penetrox for anticorrosion.
Uh Oh!! Cut the CATV Line!
Copper strap and ground rod runs!
