Minimum gauge for groud...

Got the 6' solid brass ground rod and 24' ground strap today from ICE. We have clear weather forecast here for Saturday, so I plan to pound it into the ground. I'll mount the balun to the foundation low to the ground and connect the ground strap. I ordered 100' spool of antenna wire and a 100' length of coax. If they arrive in the next day, I'll be able to put it up Saturday along with the balun and ground spike. Then I can test it out Saturday night. If I don't get the antenna wire and other goodies by the weekend, it will have to wait another week for completion and testing. I'm glad I also have the 102' G5RV to test it against. That antenna is currently laying on my roof in the shape of a sigma. I plan to leave it as is. I'd say the 6' brass rod into the earth is a better ground then the brick chimney, but I don't think it will out perform the whole uncooked chicken. I'm still not sure if I should also ground the radio in the shack. The radio is on the second floor in the house, so any ground wire would have to be about 75' long to reach the spike, unless I just ground it to the iron radiator... or a chicken. I use a six receiver, six radio MFJ- 1700C switch to go between antennas and my two radios. The new properly grounded inverted L will always be hooked up to the switch along with both my radios and all antennas. Given that one antenna is well grounded and all items are hooked up to the same switch via shielded PL-259, will the other radios and antennas benefit from that one single grounded antenna ??? Forgive me for being a total retard here... My first ever antenna was a roll of aluminum foil and an alligator clip :-) I'm making some progress... Mike D Ground the switch. To what ??? Given that the switch will already be connected to the PL-259 connection of the well grounded sloping L antenna's shielded coax, hooking up another wire to the switch from the outside ground rod will be redundant, no ??? The best I can do is put a ground strap from the switch to an iron radiator in the shack. Think that will be any help ??? Michael Yes. Lightning can induce voltage onto the cable shields that will either pass through your radios or find another path to ground. A radiator is usually a very nice ground. Will do. Thanx :-) Michael |
