YEs good thought, but a nice copper ground transmission line through it to ground level and a nice radial would complete it..
OK so 2 – 10 foot pieces of pvc pipe, with a nice thick copper line randown the center, filled with concrete for stability, joined together with a PVC joint.. that thing should be self supportive in burried into the ground about 5 feet, that would give you a 15′ tower for your radial.. hardedst part how do you hoise up a 20 foot long tube filed with concrete… probably weigh about 300 pounds 🙂 Great idea if you got a crane..
How about building a tower out of copper pipe, all soldered together and radials aroun the base.. the structure that the antenna would be held up by and about the best huge ground system you coule make.. The Fcc would have to count it as the structure thatteh antenna is mounted to, your ground lead could be 2″ and the rest could be radiator..
I kind of figured it out, i bought a 10 foot 1″ copper pipe for $14 so eight of them, a bunch of couplers and joints t’s ect, you could make a 20 foot tall copper tower out of copper for a coupe of hundred bucks.. Dang.. I may have to rip that antenna out of the ground now..
So How high of a copper tower can you make that will hold its self up.. Or how high can you make a signle coper pipe filled with concrete?? Add some guy lines.. I bet you could get a good 30 to 40 feet up with guy lines and a tower.. probably cost a god chunk of change but would get your signal up to a goot elevation and provide a awsome ground transmission line..
Maybe now that we think we have the best LPAM antenna wecan make we should try making FCC compliant big ass towers that are actually our ground..
Anyway my design is hollow, and all the ground radials converge inside the PVC.. All soldered together into a big wad.. It was super easy to build it this way and is rock solid, we had some decent winds today and the mast simply wiggles in the wind a bit.. Sweet
