Getting a signal into vintage sets?
 

Ok, with no cable out here (Catawissa, PA) the best I can do is the cord cutter internet method.

The modulator part is easy to figure out, but, how do I get a signal up to there?

What is it that you want to watch?

Assuming your modulator has a composite input, get an HDMI to composite adapter. Then pipe your laptop or whatever through the HDM to composite converter and from there into your modulator.

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.

Isn't that also known as Giants Dispair?..
