We're looking forward to following the build!

I plan start building an observatory in my shop in the next month also. Looking forward to following your progress.

Any advice on line filtering, protection, isolation ...assuming an electrician won't be hip to noise issues.

I occasionally have strikes within a tenth of a mile but no fried electronics yet. I heard of a local house burning to the ground when a charge came through a ground circuit and fried a kitchen appliance that then caught fire.

The rod is on the north side which, behind me while I took the picture are very tall ponderosa pines, so having the rod at that location does not really affect me much as I could not do much in that direction anyway.
During the monsoon months, July/August, we get numerous strikes on my property. While I've yet to take a direct hit I've lost lots of routers, modems, etc to what I believe have been ground strikes. (I have buried CAT5 between my home and garage/shop). I had a licensed lightening contractor put rods on my home, garage/studio and observatory. The observatory has a large copper cable buried all around the structure as well as a huge copper plate buried about a foot down. There are lightening interrupters on all of the electrical boxes as well as grounded bypass on all of the main CAT5 feeds between all of the buildings.
Another reason for the protection, in addition to the electrical damage from a strike, my home, as well as many in the location, use propane for heating. The propane feeds from a 500gal tank through underground pipes to each structure. Within the structure the propane is distributed via flexible gas lines. While these lines are within code and are perfectly safe to use, their wall thickness cannot carry the current that older, traditional black pipe can. Because of this, if not protected (grounded with LARGE FAT CABLES!!) a strike on my home or garage could literally explode the building as the current could easily burn through the metal of a gas line and then explode the propane within the line. This has happened to buildings in my location.
As a wise person said, an ounce of prevention is worth a pound of cure.

Another thought is to avoid burying Cat5/6 cable. Bury fiber optic cable and use media converters at each end. Not only is the bandwidth higher (who knows how bandwidth demand will evolve in the future) but the fiber will not transmit current from a ground strike.

After a month and a half of delays...plans approved, subs hired, ready to go. Should be done by mid September....hoping to miss first real snow.
