This was my first attempt brazing copper. These bolts helped hold the copper securely as I brazed them into place: Ready for brazing (attempt #2!) I drilled some holes and used M3 bolts to hold these brackets onto a 2" wide 1/8" thick sheet of copper ground plane. I then cut holes into them and added a bend using a vice and hammer: I'm using some leftover copper from the loop antenna brackets I recently worked on.įirst, cutting a couple of small strips of copper. Since my arrestors are chassis-mount I want to connect them to ground plane with a minimal amount of resistance and plenty of current-carrying capacity. You can save some effort by purchasing an alternate arrestor with the threaded hole that can be directly connected to a metal plate with a bolt. Note: these lightning arrestors are chassis-mount meaning they are grounding through the PL-259 connector and they do not have a threaded hole on the body of the arrestor. Solid-core 6 AWG copper wire from Home Depot.This was leftover from the loop antenna project. 1/8" thick copper sheet – approx 2in x 8in.1ft x 1ft 0.5mm thick copper sheet (for internal "single point" ground).Use Lightning arrestors on each coax line to shunt high voltages to ground. This system should be bonded to ground rods driven into the ground. Electrically bond all "earthed" items outside of the home together using mechanical attachment methods.A sheet of copper (0.5mm thick) screwed into a wooden board will work well for this. Use a single-point ground inside of the home.Here is a summary of some of the key points I've learned about setting up a ground system: There is a lot of information about how to setup a grounding system for radio. I want to get the best performance I can from the antenna and also take the appropriate precautions to operate safely and protect my equipment. I recently installed an end-fed wire antenna running from the apex of my garage into a large maple tree in my backyard. I have not had an antenna continually installed at my house and have not taken the time to setup a proper ground system. Until recently most of my ham radio activity has been QRP/remote.
