Folks, Thought I'd try purchasing a book from antennex.
I now have three of them.

So far, they have been very accessible pdf files.
Go to

http://www.antennex.com/

nd have a look around.

Also, alll the info at the old www.cebik .com site is available for free. 
You just have to register with them.

Thought this might benifit some one out there.
