(meteorobs) antennae
>>>>Scott was talking about radio astronomy. I remember an article in
Sci
Amer. a few months ago in the amateur scientist section. It dealt with a
wound core kind of like an electromagnet that could detect low frequency
waves. ......... Could a used satellite dish or a waveguide work? <<<
Hello 1st,
Receiving meteors at very low frequencies (VLF) is an understudied field.
There are only a few experimenters attempting this. Indeed, meteors
--mainly the occaisional *very large fireball*-- may cause a receivable
very low frequency emission. But I don't think there are many papers on the
subject.
The common "satellite" dishes are designed for much higher frequencies and
I don't think they have application in radio meteor work.
Fortunately, for $20. ( twenty dollars) you can but a Radio Shack FM
antenna that will be quite superb for working meteors at near optimum
meteor frequencies. One could hardly do better than this specific antenna.
Clear skies,
Thomas A
