At the DTV transition in June 2009, WPVI's signal was terrible. The FCC granted a power boost and it was satisfactory at my Mount Laurel location. However, all this year, the reception has been marginal. I suspect that the FCC took back some of the boost. I have a large vhf/uhf antenna, with a preamplifier and booster. I am 20 miles from the transmitter. I called and emailed WPVI a numerous times. Their technical engineer stated that WPVI would be building a polarizing antenna and to go online this pass summer. Don't know if this happened. I receive numerous uhf channels nd cannot understand why WPVI stayed with vhf. As I understand, with uhf, the FCC can grant a large power output, but not for vhf and especially the low band vhf. Are you having problems as well and do you have any additional information that may help me?
