[amsat-bb] Re: Arecibo on 432 MHz Moon Bounce (some calculations)

The mathematical model is well proven. The difference between a isotropic
and a dipole antenna is 2.1 dB. The practical accuracy of field strength
measurements on a antenna range is +/- 3dB, making this whole discussion
theoretical. (Just In The Interest Of Science) or JITIOS!

I guess because it's impossible to build an isotropic radiator and therefore
just as impossible to measure it.
Why would I believe, or want to use, something I can neither have, use or
measure?

An isotropic antenna doesn't exist.
