KSLA-TV's 1st transmitter tower in Mooringsport, LA stood at 1709' before it fell in 1977. It was replaced the same year with the current tower, which stands at 1,650', and carries KSLA's signal from the station to 387,060 homes across the ArkLaTex.

You may have noticed a disruption in the KSLA News 12 signal on Friday. We are currently on a back-up transmitter system while our engineers work on the issue getting our main system back up.
 
The issue is the with the antenna, which is believed to be failing, and the high power of the main transmitter has the potential of burning the antenna completely, causing a prolonged outage. As a precaution, we are currently using our backup transmitter, since it is less powerful this minimizes the risk of burning the antenna.

Our signal was off the air for about 30 minutes, beginning around 11:00 a.m. Friday, while measurements were done on the antenna and line, during which we had to be disconnected from the transmitter. This measurement allowed us to locate the source of the problem at two locations, 1500 Ft (around 5/6 of the total height of the tower) and at the top, in the antenna complex.

A longer interruption is scheduled to take place Saturday night for the antenna and line evaluation and repairs. A tower crew is currently on the way to Shreveport to climb the tower at night and complete the repairs.

While we are a lower-power antenna, some viewers who receive our signal via antenna might find taking steps to adjust the antenna might improve reception. As signal booster may help. An outside antenna is more likely to pick up the signal than an inside one.

We apologize for the disruptions and hope to be back up to full power very soon so that you can enjoy all of your favorite KSLA News 12 and CBS programming. This TV ArkLaTex - DT 12.2 and Bounce ArkLaTex - DT 12.3 are also affected, since these are carried in the same Digital signal.

Viewers watching us via satellite and Comcast in Shreveport are not affected because we have a direct signal feed to these distributors from our studios.

Thank you for your understanding and patience.
