Waveguide questions
I'm a beginner in µW. And, after a lot of reading I've some questions unsolved:

"Is my car an all-terrain or a sport one?"
It depends on the use..... Usually, base stations want to communicate with mobiles geographically dispersed and a omnidirectional antenna is mandatory, but sometimes will be enough to reach a repeater, in wich case a...
Re: How to find out the operating frequency of a Co-axial ca
If I get it right,
coaxial cables have not such as "operating frequency". Propagation in coaxial cables is TEM, which has no cutoff frequency. You only have to deal with it's attenuation per longitude wich increases with frequency...

Does anybody knows how the "auto" function works?
I've read something about you can tune from 8Mhz up to 1,5 GHz by means of an external oscillator in the 17 - 28 MHz range. What is this relationship? I understand nothing.
Or... does anybody have the user manual? :D
Thanks.
