Possiblly using other Bands for which we may have RF exciters.

622.062 = Television = 1.4811 x C Upper Sideband unwanted but suppressed by SWR

420.000 = Ham = 1.4811 x C = F0 Longitudinal Wave Transverse Wave

283.573 = Military = 1.4811 x C Lower Sideband unwanted but suppressed by SWR

===============================


333.041 = Military = 1.4811 x C Upper Sideband unwanted but suppressed by SWR

224.860 = Ham = F0 or Center of Oscillation by standard C Transcerse Wave

151.820 = MURS = 1.4811 x C Lower Sideband to tune to; unwanted but suppressed by SWR


If one were to tune to best SWR for 151.820 this most likely would support the Longitudinal wave as a primary and sidebands as follows:

224.860 = Ham = 1.4811 x C Upper Sideband unwanted Transverse Wave but suppressed by SWR

151.820 = MURS = 1.4811 x C = F0 Longitudinal Wave

102.504 = Broadcast = 1.4811 x C Lower Sideband unwanted Transverse Wave but suppressed by SWR

Also you may want to think about a coil at the feed point of the open end that is fed from the feed point by wire that causes the magnetic current to flow in the opposite direction to cancel some of the magnetic current.
This may however cancel the Longitudinal wave since the two would be out of phase. However if a resistor is placed in line with the coil then a partial decrease in the magnetic current may be achieved without full cancellation of the Longitudinal wave.

You may have to make the feed a bifilar pancake coil.

Another option is to place a primary coil around the can at F0 and then wind a secondary coil around that in the reverse direction Tesla coil style. This may be tried with the standard feed point that you have but not energized, hence it becomes a passive tuning fork style radiator ala a sound style transverse wave from a speaker.

Another option is to use your standard feed point but connected to a bifilar wound pancake coil, for magnetic current canceling. Also you may want to try placing a small ball at the top of your feed point instead of the disk.

Just some ideas I have been toying with myself. You are almost there so I hope some of this may help.

I understand and accept that longitudinal waves exist and have been transmitted.

My uncertainty, and hence my questions, is around this whole matter of "grounding."

From my (Faraday-like) physical understanding, I can see how both the transmitter and the receiver need something to "push against" in order to resonate from a wave, in the same way that an oscillating spring has to be fixed at one end.

So if the transmitter is sending a wave into space then it is pushing against the Earth, and (from your comment about Wardenclyffe) if it is transmitting into the Earth then it has to push against the aether. Either way, it has to push against something much bigger than itself in order to transmit (or receive, i.e., resonate to) waves.

That is actually the reason I came up with my first idea of partial concentric spheres:

Hi all,

I made a new drawing of the lamare longitudinal dipole antenna, with dimensions for 1296 MHz:

Updated spreadsheet with my calculations:
http://www.tuks.nl/Spice/Lamare_dipole_calc.xls

Oh yeah, I almost forgot. Aluminum and copper can be soldered together:

solder-aluminium

Based on the last update in the above post explaining we can choose any odd multiple of 1/15th of the circumference of the big sphere, we can also opt for 5/15th, which would be 1/3d.

Therefore version 4 of the design:
http://www.tuks.nl/img/Lamare_Longit..._dipole_v4.jpg

Grrrrr.

How much is 360 divided by 3??

Right, 120...



Yep, that's another number than 90....

So, back to the drawing board....


Update: Here's version 5:

With a high-res version for printing, etc:

Update 2:

I have done some calculations on the surface area of these so called "spherical caps", which you can find in my spreadsheet:
http://www.tuks.nl/Spice/Lamare_dipole_calc.xls

It turns out that a cap for 1/5th has a surface area of about 86% of the surface of the small sphere, while a 1/3 cap will give avout 225% of the surface of the small sphere.

So, I think we'll go for version 3. Easier to make, and more in balance with respect to surface area's (== self capacitance and/or charge density):

High res version:

And that's it for today...

I never went further with those ideas, because they are pretty hard to construct.

It's an issue I've looked at before too. I'm looking at a simpler lack though--there are a few video clips of Meyl's boat and airplane, and they seem to be the only ones showing a non-wire connection. All the other experiments seem to use a wire to simulate ground. One of my first plans once I get around to serious Tesla experiments(will I ever?) is to do this.

The "wire" is there. It's actually the water the boat floats on which is used as a wire. See:

Update:

Airplane? Never seen that.....

It also occurred to me that perhaps if you either shortened you can or lengthened your feed point you may find some interesting things. Especially if you used a ball on your feed point.
I have wondered what happens if the ball is near of just outside of the mouth of the can concerning Longitudinal waves. It may be that the can may act as a reflector with an active ball resonator.
I have also wondered, that if the ball size is not so specific in size in Tesla's works how do really determine a wavelength in longitudinal. Yes, in theory it is 1.48 to 1.57 times C. I used the 1.4811 x C as that seems to be the physical reality of your SWR charts at 1296 Mhz. So the can must affect the velocity factor in real life, as does a coax cable for C.
Can we use EM math to determine the wavelength of Longitudinal waves just because we do know a difference of C. Does the length of the Longitudinal Wave become different since it should not have Magnetic inhibition of its wavelength (magnetic inductive resistance) as it does in EM. If there is no magnetic inductive resistance of the wave, then is not the wavelength different? Hence this is why my other suggestions of varying the feed point with a ball termination.

Is not the ball in front of the can similar to the ball in front of your parabola. A push off reflector. As the speaker is an emmiter for sound pushing off from the magnetic driver and or the back of its resonance box.
My understanding is that Longitudinal waves are an electrical equivalent of a Sound speaker. Compression and uncompression needs something to push or pull against.

A parabola of the right size may be had perhaps by lining an audio parabolic microphone base with aluminum foil. This allows feeding form the base which is the center of the parabola of from the microphone mount position. This seems like about the right size for 1296 Mhz, and or 2450 Mhz or WiFi.
