Is this all what I need to broadcast on the FM frequency (87.5 to 108 MHz)?
What the range that I'll get if it was 1000W?
What is the difference between the "Exciter" and the "Transmitter"?
Your real problem will be legal. In all countries you need government permission to set up a broadcast station and in many countries they never give it to individuals.
You will also need a place to transmit from, feeder cable, an antenna and perhaps a mast or tower to put the antenna on.
The hight above ground of the antenna and the local geography make a big difference to the range. You will get more coverage from the top of a mountain than the bottom of a valley.
That's natural to need a place to transmit from ,but:
What is feeder cable?
The high above ground of the antenna and the loca geography make a big difference to the range. You will get more coverage from the top of a mountain than the bottom of a valley.
Feeder cable is a coaxial cable. You should use 50 ohm cable able to transfer 1kW of power at 100MHz.
Coverage depends on transmitter power, antenna gain and hight of antenna above the terrain. Power of 1kW with antenna gainof about 10dBi can be enough for range of 60km.
If you want to transmitt stereo modulation you will need a stereo coder or stereo generator like model 710A DIGITAL FM STEREO GENERATOR from the same QEI company.
