The N4NEQ Atlanta ATV Repeater, also known as the Sweat Mountain or Big Shanty repeater is located on top of Sweat Mountain. The exact location is where Cobb, Fulton, and Cherokee Counties meet.
This repeater has a Microwave input on 1253 MHz (1.253 GHz) and the input is F.M. TV (like satellite TV). The output signal of the system falls on 427.25 Mhz and is a standard AM TV signal as used by regular, home televisions.
As a matter of fact, a standard cable-ready TV or VCR can receive our signal when tuned to CATV channel 58! Be sure to select the CATV tuning mode. Our signal is vertically polarized, so you must use a vertical antenna. A preamplifier helps a lot. Coverage has been obtained to high locations up to 100 miles distant!
The repeater will retransmit a signal that appears on its input. If the NASA shuttle video is currently being shown, a local ATV signal on the repeater input will override NASA.
