I live in the DFW area and I noticed around May 1st that KDFW's signal strength dropped by about 40%. Normally I enjoy about 90% signal strength and now I'm getting about 50%. THE PROBLEM IS UNLIKELY TO BE YOUR ANTENNA. Perhaps they're doing some maintenance on the tower, or KDFW has a need to reduce the power temporarily (or maybe it's those absurd arches they are placing on the bridge over the Trinity River interfering with reception). Whatever the reason, be patient and just wait it out. I'll repost when my signal goes back to normal strength.
