Before June 12th I could get all the locals OTR 5,11 19,39 easily. Now 5 is weak, 11 I cannot get, and I can get 19, 39. I assume my problem is that my current antenna is a UHF. 40" Boom Length, 17 Elements Outdoor Antenna for UHF-Only - RadioShack.com Any suggestions. I also have been using an amp. Have not tried it without since June 12.
