Hi, I am a newbie to this field. I searched most of the topics and can't find the answer I am looking for. I have a budgeted project which do not allow me to use Cat5 or fibre optic transmission. Distance is over 600 metre and the choice is only coax RG6 cable. I was told I could use an FM Modulator for both end or every 150 metre. Pls advise, where can I get this modulator and how does it look like? Is FM Modulator the only option?
