In this part of the state, the four active channels over the air are RF-11, 12, 21, 22. These come from Penobscot Knob, 35 miles northeast of Catawissa.
Connect a DT converter to a rooftop antenna like an 4-bay bowtie using RG6 and a matching transformer. Don't even consider using an indoor antenna in this area. The best spot is high above a roof where its not blocked by buildings, trees, etc.
Once you have stable reception to a DT box or HD set with ATSC tuner, connect the A-V outputs of the DT converter to a channel modulator, which in turn has a monopole antenna connected to the output, cut to 1/2 wavelength of the channel you're broadcasting. This makes for easy use of any TV using rabbit ears.
Using Blonder Tongue "AM" series ( ebay for $20-40 each) , I broadcast analog on 3 VHF and one UHF channel this way.
