Default Antenna gain question

Thank you very much for your corrections to my translations...


Hi Miguel,

You do very well with English.

If you wish to be very, very, very specific, then yes DC will radiate.

Let's take something a little more practical than a cyclotron - the
monitor you are looking at to read this. The CRT is accelerating an
electron to strike a phosphor to illuminate a pixel. We will neglect
that light radiation as not being part of the discussion.

That electron will be accelerated by a field of some 20KV. What is
its frequency?
34.6 exaHertz
the wavelength of roughly 1/10 the distance of an electron orbit
around a Hydrogen atom.

Now, for something completely different. Does a car driving 40
KM/Hour down the road radiate? If you wish to be very, very, very
specific, then yes the car will radiate by the same principle at
5 zetta-yottaHertz
