New Antenna Design

RS2 Fora Comments - Sun, 06/29/2014 - 11:10

Rainer has come up with a spherical antenna structure, designed to amplify the electric field effect. The idea was to increase the surface area, which will increase the electric field while distributing the RF energy in a more spherical pattern, rather than radial, to lessen the possibility of interference.

We went to great expense, using stainless steel mixing bowls from Bed, Bath and Beyond.

The sphere on the left is the receiver, which is designed as a capacitor with a dielectric between the halves and an internal coil to make the resonant frequency near the 2-meter transmit frequency (which also helps eliminate noise, which is considerable here in the city).

The right sphere is the transmitter, just two bowls bolted together.

We initially tried to put them on the pole setup from the last experiment, but they were a bit too heavy and kept tipping over. Made some quick pedestals, but the results were only showing the speed of light in all tests, indicating that the RF was dominant. Some checks indicated that the dielectric field was just jumping to ground (only 2 inches away), so we've made some extension pipes to get them up higher and will re-run the tests this evening.

Also, I took some photos of Rainer's vacuum tube experiments that are described in his papers, so you can see what they look like. We may try to fire these up again as well, now that there is much better technology available than there was in 1979.
