Macon, GA WGXA-DT  1000. 226.0 dH 32°44'58"N 83°33'35"W DT-CP
Macon, GA WGXA  1.16 155.0 d 32°44'58"N 83°33'35"W DS-STA
Macon, GA WMGT-DT  110.0 189.0 H 32°45'12"N 83°33'46"W DT-CP

The number after the channel number (note that the channel number in brackets is the actual RF channel, not the "branded" channel... WGXA-DT is 24, WMGT-DT is 41) is the power authorized in kilowatts, the second number is the height of the antenna in meters. The first line for each station above ends with DT-CP, that means that they have a construction permit from the FCC for the facilities shown.
The second line shows the current power level and height. As you can see, WGXA is currently transmitting 1,160 watts from 155 meters (approx 508 feet). WMGT is transmitting 3,300 watts from 143 meters (approx 469 feet).
WGXA is currently building their full-power facility, and when it's complete (I personally hope within the next 6 weeks, before NASCAR starts), they will transmit 1 million watts from 226 meters (approx 741 feet).
I'm sure Ralph will pipe up with the latest on the construction at WGXA.
WMGT has a construction permit for 110,000 watts at 189 meters (approx 620 feet), but I've not heard a word about them starting up actual construction, and I wouldn't hold my breath on it happening anytime soon.
Incidentally, the DS-STA at the end of the 2nd line for each means they're operating under a Special Temporary Authority from the FCC. Basically, they went before the Commission and said "we can't afford to build this right now, but we know we have to have a digital signal on the air, so could we please have a special permit to go on at really low power?"
