hello people . i don't know if this is the right place to ask , but I'm studding for my cisco ccna and now I'm learning more about radio waves and wifi networks and i fall in love with the subject , what i don't understand is what's the difference between a radio and a antenna , because i asked in another forum they told me that the radio create the radio waves and the antenna only transport the encoded signals of information inside the waves . i just would like to know more i don't like the feeling of something messing because for me the waves are spread using the antenna ,also because antenna's are semi duplex ( can send only to one other antenna at the same time) so how can it works at two different frequencies at the same time ? hope you help me see it better thanks
