Straight line trajectory

[KB9MZ]

If a lazer can achieve a straight line trajectory as well as the most efficient use of propagation via point vector. Why not the same for radio waves ie point radiation? If an electron operates as a single particle (acceleration of charge)
in propagation inside a scope, why not the same for radio antennas that can accelerate particles in a continuous straight line?
Final question. Why does a radio antenna not work on the same principle
other than the longer, bigger, better approach that hams take. ? Seems like the Classical physics approach which is based on boundaries and vectors should not vary so much when accelerating a charge when it should be standard for all.

Lasers are optically focused, and because the mirrors are so much bigger than the short wavelength, they're much better at focusing the beam to a point. To do this at even UHF frequencies would require a monstrous antenna array.

I once did a gig with an OEM of 23- and 38 GHz point-point digital radio equipment (Innova Corp). Their claim to fame was that, because the wavelength was so short, they were able to use optically-focused antennas. Naturally, the RF units were mounted to the antenna, eliminating feedline loss. The IF to the control unit was 1.2GHz. When I left, they were working on going to 50 GHz.

I was thinking pencil type lasers and to me optical means light so we have a radio connection. Doesn't a reflector reflect? How would a pencil laser compare
with radio for point to point? I am all at sea with laser stuff.

Advanced amateurs are experimenting with laser and light communications; several VKs, including Mike Groth VK7MJ and Rex Moncur VK7MO are in the forefront.

I got the flame suit on just in case I am completely wrong. KC Masterpiece only, PSE.

The difference I see in the radio wave (sine wave energy)when compared to the laser energy is you have less/don't have the Lorentz or Conformal invariancies in the laser energy.

A reflector is a reflector but 1 that can turn a sine energy wave to a laser/continous energy wave is a special guy. To my way of thinking, for this type of reflector to work it has to amplify the same tiny part of the sine wave each time so there will be no "gap" of straight line energy in between the rf sine waves. If this happens rf energy can look like a laser's energy at the other end of the "tube".

Thank you for sharing that with the group. So AUSSI AUSSi is still in the experimental mode? Was it the Tasmanian devil that made you do it?
To be honest it was way above my pay grade on the first reading but I will go thru it again so your efforts will not be wasted
Cheers

You are a smarter man than I am Gunga Din!
I was looking at it as a acceleration of charge only that would put it into the Classical Physics mode of which light is part and parcel of. Radio is said to flare out as per light yet the flare seems to be the format supplied by the reflector. If light or laser is in the form of a particle then radio propagation should not be barred from a pencil type trajectory. Ofcourse that is personal intuition only knowing only part of the facts. When the Aussie said there was bounce off from the haze intuition pointed to similarities i.e dense particle rebounds in series to form a curve rather than refraction.

Who sells more "home" antennas than anyone?

The DBS Satellite companies (DirecTV, Dish Network, et al) do. Millions and millions and millions of them.

They all use 18-36" dishes, depending on location and application.

I want to see them use something smaller, as it would save them billions of dollars and maybe we investors could benefit from that.

TNX for the information Art. Your describition of the pencil lazer is spot on, finally made the light go on in my head after I thought about it for a while. Very simple idea and it might prove that bigger isn't always better for antennas. TNX once agn Art for "pointing" me in the right direction.

I wish I knew more! We all know that a solenoid will accelerate the mass inside of it while it is in the confines of the contained field exactly like a bullet. But it is particles that are doing the driving. If the ferrite was not in the solenoid we would still have projectiles but each start from a different point on the surface of the windings to form what appears over time a helical path exactly like the helix pattern of our DNA. so mass with spin is everywhere and common with all in the Universe starting from the day of the BIG BANG.
With the solenoid the external magnetic field is prevented from forming by having the current flow change direction as the wire moves forwards and backwards but on top of each other in a concentrated internal field such that it never gets the chance to flow nicely between a capacitive field and a inductive field. Thus the external magnetic field never gets to form ad it has no movement as we know it and with the field so goes the magnetic fields foothold called skin effect. Now force vectors can get right close to the resting particles without wasting energy pushing thru the resistive skin depth.
You can visualise these particles as being so dense that to the eye they have the appearance with a liguid so in effect we can supply a nozzle to the flow
that is so thin that it can cut thru matter like a knife with butter.
Everything I have stated above describes radiation which is created by the passage of a current thru the magnetic filed inside the confines of a capacitor where a magnetic field is also created. Thus a simple hollow solenoid can take on the phenomina of water in a pipe or a bullet in a rifle barrel where the particle in flight is of the smallest mass possible so it can
be accellerated to the speed of light ( max speed because it is the smallest particle of mass) which is the equal and opposite reaction required to that of gravity with spin.
The idea of length in propagation comes from the logic of the length of a wave, where actually Gauss's law of static particles when added by movement or made dynamic provides the same format provided by Maxwell for radiation
So are we to ignore mathematics this one time for waves. As for particles we have billions of them floating around on earth looking for a diamagnetic surface ( conductive but unable to retain magnetism) where they can rest
just like the skin on water that can support an insect. Remember that you can only accelleration mass with a force point or vector in our Universe.
Nothing but nothing is new in the above, science recognise all the phenomina
occurences as factual and not just made up. The only thing they will not introduce is that Gauss.s law of statics when made dynamic become the same as Maxell's laws. They will not deny this existance but just don't want
it to be discussed as it reveals their impotence to accept change which they in the past 100 years have been ignored. Don't believe me then do the math.
Don't understand the math? Then call on your Physics teacher or professor
If you prefer to do nothing as your education did not take you that far then call in pseudo science.

Try doing the same with a magnetic or electric wave!
