Hi Judy, it depends on where you live, as to the options available to you. To seek free options first put your zip into this site to see how many stations are within 60 miles of your location: https://www.antennasdirect.com/transmitter-locator.html. There are about 18 towers within 60 miles of me. Each town broadcasts multiple channels depending on the network they are connected to. With my 18 towers, I get 68 channels. If you can get enough channels in your area, it may be worth investing in a very good rooftop digital antenna. I have a Clear2 which cost me about $60 bucks, but their are even better ones out there. Depending on where your towers are located, you may want a very strong multi-directional antenna. That’s going to be the best option for free OTA. I ran my antenna directly into where my cable connected to house, so all my lines in the house received the signal. I also purchased a $15 in-line signal booster. You can also find those on amazon or google them. Also, are you sure hughes net is only provider for your area? make sure you check every option to see an unlimited internet provider as unlimited internet and streaming device with Terrarium TV is ultimate cord cutter dream. What is your zip code? I’ll check any additional options for you.
The question of "when does it make sense?" can easily be rephrased as "how much money can I save?" and one of the biggest factors will be the price difference between combined internet and TV service or just internet. These are also the options that vary the most widely based on where you live, and the availability of promotions or contracts that can keep prices down for a short time.
