W3ESX Posted August 19, 2021 Share Posted August 19, 2021 Hello, After having spoke with several seasoned hams about my setup, I've come to the conclusion that I need a grounding system for my rigs and antennas for safety purposes. For the past few days I've been doing some research and I've come up with a system that I think will work and will last, but I have some questions and I would like some feedback. Thanks in advance! Summary Basically, I want to: drive a new 8' long (5/8" diameter) ground rod on the side of my house, fasten a 1" width copper strap onto the rod (using a clamp) and run it up the siding of my house and into an enclosure (details to follow), fasten the copper strap to a grounding bar within the enclosure, which also has lightning arresters mounted to it mount the enclosure to the side of the house and run the coax into the enclosure, through the arresters, and then back out into my shack via a passthru panel Enclosure From my research, I think a simple AC disconnect box will serve as a great enclosure. I will of course rip out all of the guts that I don't need. I will use the existing punch-outs to create ingress/egress for the coax, with clamp-downs (my electrician terminology is weak, I know 😆) to hold the cables in place internally. I have some moldable non-adhesive sealant that will go around the ingress and egress points to waterproof them. The grounding bar in the enclosure as-is is pretty small and the arresters are pretty bulky, so I think I will need to buy a new one. However, none that I've found on DX Engineering or HRO have been the right size (they are usually 10+" long and the box is 7" long). Any tips on a good one to purchase? I don't need a big one because at this QTH I will likely not be able to have more than the 2 antennas I already have (well, one operational, one planned). Materials This is pretty much everything I think I will need for the project: 1x AC disconnect box 2x Diamond Antenna SP-Series Lightning Arresters (one per antenna) 1x ERICO grounding rod 1x DXE Copper Strap Bonding Clamps 1x Set of Copper Ground Strap Jumpers (for jumping from passthru panel to enclosure) 1x 25' Run of Copper Ground Strap (for grounding from enclosure to ground rod) 1x DXE Copper Cleaning Kit (for making sure my connections stay happy and healthy) 1x MFJ Universal Window Feedthrough Panel Questions I have the following questions: Which do you think would be a better setup: having the enclosure mounted high up near the antenna (shorter coax runs, longer ground strap runs) or low down near the grounding rod (longer coax runs, super short ground strap runs)? I'm leaning towards the latter because RG-8X is pretty cheap, and copper is expensive. What product(s) are recommended to serve as the "raceway" for the copper strap and/or coax from the enclosure to the grounding rod? Needs to be mountable to standard vinyl siding with minimal damage, and of course weather-resistant. Thinking D-channel, but haven't found any that is specifically listed as being outdoor-safe. Also has to be pretty wide diameter, as depending on the setup I may want to also run the coax through it along with the grounding strap. (Is it safe to run the grounding strap parallel to the coax? Is it safe to run the pre-arrester and post-arrester coax lines parallel to one another?) Any other red flags from reading my plan, either safety-wise or code-wise? I do not live in an HOA (thank goodness) but want to maintain code adherence wherever possible to avoid damaging value of home (and pissing off XYL). 😍👽😺 === Thanks!!! === 😍👽😺 I am open to any and all (constructive) feedback and am happy to engage in discussion or answer any clarifying questions. 73 DE W3ESX Link to comment Share on other sites More sharing options...
