thank you for the video, that was an awesome assembly. i am currently building something similar, however the difference on mine is that the grounding bus will sit outside of the house and the antenna cables will pass through the arrestor that will be grounded to the bus that is grounded to the grounding rod, before making their way in to the house. I also am going to run the grounding rod line that grounds the bar , into the house electrical panel to bond with the ground already present. i believe this will help level out the voltage potential difference all around.
Thanks. Gave me some ideas. Generally, it is best to have the surge suppressors outside. Keeps the sparks and hot metal outdoors. May be less of a fire hazard. Thanks again. N0QFT
Very super good, question: what size thickness ground cable wire to the outside rod do you use? and what size from the distributon bar to the radio and other apparatus? many thanks
With all due respect, I concur that this is a troublesome solution. I can find no source that recommends placement of lightening "arrestors" inside a building including online ham radio authorities, the ARRS book referenced in the video and online electricians and engineers. The misnamed arrestors do not in fact arrest the lightning if there is a direct strike. They offer some protection from nearby strikes and static discharges. This setup is in violation of the NEC in the U.S.; I don't know about regulations in the U.K. I expect the setup works just fine for fair weather, but I am concerned about an increased fire risk in the event of a nearby lightning strike. While neatness is desirable, safety should be paramount. Kind regards, John - KK7JBZ

Liked the video .. :) Was there any noticeable difference in noise level ?

Does the earth bar have to be mounted to the wall
What size grounding wires did you use for your equipment
Can I ask you where you sourced the 2 x 4' earthing rods please?
Do you have an issue with a lightning strike bringing the lightning into the loft before it hits the arrestors?

Overkill......
better then underkill
