[amsat-bb] Godd info about parabolics feeds and antennas

[fredf@xxxxxxx]

Hi!

If you need informations for feeding parabolic antenas, 
and more,see the " W1GHZ microwave antenna book" online 
at :

www.qsl.net/n1bwt/contents.html

The download of the entire book is about 6Mb,but you can 
just get the chapter you need.

Itīs full of very interesting information for 
construction and testing feeds and antennas at microwave 
freqs.

I have constructed the VE4MA type for 1,2 and 2,4 ghz a 
couple of years ago (my 3 meters antenas have a F/D ratio 
of about 0.3 ,so it was the best solution), they work 
fine,if you need any particular constructional info just 
send me a mail at:
microwave@clix.pt
Thanks to W1GHZ

Good luck!
