Also what you will find is that most repeaters hold built within amplifiers to boost the productive (lossy) signal up to the artistic signal.
A repeater is a device used to repeat the signal after every couple hundred foot (not exactly sure how far). The piece around a repeater is that eventually it will start to deteriorate the signal because of clatter and interference.
An amplifier freshly boosts the signal out a small distance, and still maintain the signal.
just similar to it says
a repeater merely repeats the frequency it is given and sends it posterior out - it is used to broaden the distance, example - read aloud your signal can merely travel 200 ft next get delicate, a repeater grab the signal since it weaken and sends it vertebrae out
an amplier will pocket alike signal and boost it appropriately, depending on its capability
