An rf module short for radio frequency module is a usually small electronic device used to transmit and or receive radio signals between two devices in an embedded system it is often desirable to communicate with another device wirelessly this wireless communication may be accomplished through optical communication or through radio frequency rf communication. Since high gain antennas direct most of the rf energy toward the horizon and not toward the ground high erp transmission systems such as used for uhf tv broadcast tend to have less ground level field intensity near the station than fm. These rods can be mounted virtually anywhere on a roof see photo 5 and unlike the microwave dishes they emit radio frequency rf energy uniformly 360 degrees known as omni directional.

Erp is the transmitter power delivered to the antenna multiplied by the directivity or gain of the antenna. Generally the highest exposure levels are at the same height and directly in front of the antenna but the exposure levels rapidly decrease with.
