What does a repeater do??

Question

I was just wondering caus my cousin is a cop and he said that their radios run through a repeater to get coverage all over the county, so I was just wondering what exactly they do...

Answer 1

A repeater for two-way radio is a base station located at a place that offers very good coverage of the desired area. This is either a tall building or a nearby hill top. It can be a single site or multiple sites for even greater coverage. It receives the car mobile or hand-held radio transmissions and sends the signal back out on a real time basis. In other words, it'w transmitting the signal back out as it receives it. To do this, the repeaters and the radios that access them use different frequencies for receive and transmit. This gives the hand-held or mobile radio the same power and range as the repeater has at the good site. The repeater can easily have an effective radiated power of 1,000 watts or more.

Answer 2

A repeater boosts the signal so he can hear the radio everywhere he goes. If there wasn't a repeater, it would be like a radio station when you leave the area - gets softer and more static. Same with cell phones. That's why you lose your cell signal when you aren't near a tower. The tower repeats the signals.

Answer 3

They are hooked up to both Area 51 and the Belgian Beast Computer System. They broadcast radio waves to satellites were fallen angels in UFOs in the Second Heaven can listen. If they deem anything critical towards the adminstration of the One World Gov. they will order the President to seen ATF and Navy Seal assasians in black helicoptors to their home at night.

Answer 4

i think it sends the signal further. im pretty sure its like a booster. it takes the signal with the message and 'repeats' the message over a greater distance (its using more antennas & towers to bounce the signal & send it further).

at least thats what i think. :D
