Operating Safeguards
Load Impedance
It is a known fact that our FM equipment enjoys 50-ohm load impedances. So
much so, that it is imperative you maintain 50-ohm impedances throughout your
system. In return, your equipment will provide you with maximum power transfer
to the antenna and decreased reflected power heading back towards the
amplifier pallets, reducing the amount of magic smoke that gets let out of the
equipment. Before anything is turned on, ensure that there is a 50-ohm path from
the output of each stage to the input of the next, all the way to the antenna.
Operating Warnings
Our FM equipment is designed to reliably generate a specific RF output power
level. Failing to adhere to overdriven amplifier, high reflected power, and high
temperature, and other warnings can decrease the reliability of your system, and
frankly, makes our repair department busy and grumpy. If you need to transmit to
a little larger coverage, you are better off increasing antenna gain, and more
importantly, antenna height above average terrain. On FM broadcast
frequencies, insufficient antenna height puts an upper limit on your range,
regardless of power levels, as the
distance from your antenna to the radio
horizon is limited.
