I live at the East edge of Rockford, near Alpine and Charles, which is near the highest point in Rockford. I am using amplified indoor antennas (2), one is a Terk which includes rabbit ears and the other is a Radio Shack which also includes rabbit ears. I find it nearly impossible to lock onto WREX, channel 13. Is the correct Transmit Number for this station 54? I did find that the Rabbit Ears need to be about 21 inches long to lock onto WREX. The other 3 Rockford stations lock in very well. Right now, I have the TV connected to the Terk locked onto 13.001 and 13.002 without breakup. Since I just looked up the transmit number, 54, I am going to try to set my other TV to that number and see if I can get a lock on WREX on that TV.
OK, I just went to the other HDTV tuner which shows Transmit number, Channel number and Signal Strength.
I set the transmit number to 54 and was not able to get any signal no matter how I adjusted the antenna. Then I set the Transmit number to 13. After extending the rabbit ears to full length, the meter jumped to 57%.
Apparently the reason that I was getting a good signal prior to the switchover, is because the transmit number was 54. I assume that 54 was UHF and 13 is VHF. Maybe now, thanks to the help found here, I can get WREX good enough to view it on that primary over-the-air tuner. :-)
After more tweaking, I got the signal strength up to 65. This is good enough to watch both WREX programs. The rabbit ear length is 19 inches for both. The tips are 6.5 inches apart. This Radio Shack antenna has a mesh reflector with a wire bow tie in front of the reflector and rabbit ears behind the reflector. The bow tie had to be rotated a little clockwise from full counter-clockwise. The upper left and lower right wire segments extinding from the center hub now form a vertical straight line. The amplifier dial is set to three o'clock, not quite maximum. Rabbit Ear length and Bow Tie rotation are very critical! Signal strength is about 90 for the other 3 Rockford stations.
The antenna is sitting just below and just in front of the wall mounted TV, which is not ideal.
Before the switch-over, I used the Terk with this tuner and had it on a high shelf in a nearby closet, where the Terk was getting all four Rockford TV Stations most of the time.
