I built a large cap to hopefully investigate many circuit claims that there are
no diagrams for what so ever, and to investigate the possibility that I could
achive a stronger power transfer from an existing circuit developed by a man
in Meadville , PA (last name is Prentice) that uses a 18 foot long antenna to
extract power from a half mile long conductor.
I was fooling around and hooked it up to my TV set and now don't want to
remove it. best antenna I've seen for local reception so I will have to build
another one. I'll build a much larger one next time.
How I made it:
I first took a 4 inch can lid and a piece of cerial box made a template by
holding the lid and tracing around with a fine point marker.Sharpie worked
good for me.I set the lid down so each overlaped 1 1/2 inch making a
triangle of 4 inch circles. I free hand drew counter curves between the
radiuses Then I cut it out with scissors and traced the template onto roof
flashing , 4 pieces aluminium, 4 steel. The next part is a little bit of shoddy
work to make it (quick) With a tubing cutter cut a 1 in. piece and an 18 in.
piece of 3/4 in. pcv pipe.Take the 1" piece place it on the plates at the edge
and center of a four inch radius trace a line, draw a smaller circle inside of it.
cut out the smaller circle and cut a few radii cuts out to the traced line from
the pcv pipe.Bend these sections sharply 90 degrees.Use a tiewrap gun to
tightly clamp the plates to the 18" long piece of pcv pipe.(every other one
aluminium). I used a two inch gap because at some point I intended to
apply high voltage dc to the cap.Put gap filling super glue between the plates
and the tiewrap(don't get it on the pcv pipe). Make a L shaped long strip to
solder to the one side top radius. Cut (3) 1' wide 6" long strips of aluminium
bend 1 inch tabs on the ends, place them all together drill a small hole for
nylon bolts.On the opposite side from the soldered on l plate drill small holes
for the nylon bolts.Bolt the short strips between the aluminium plates and on
one end add a solderless eye.Drill and bolt a solderless eye on the soldered on
strip and it's finished. Makes a good antenna. Very directional though.
funny thats how i get better reception on my radio and i did something similar when i was in junior high to my tv. my mother was shocked to see how well I picked up LA tv signals in Clovis.
but grounding your antenna with a cap is the best something to do with zenic ground waves. i think tesla may be to blame for his secretive work with RCA. :)
Got some pics ? Jim out
Can you post a photo?
