We just pulled into our campsite, which doesn’t have cable TV. So I turned on the antenna boost (green light) and did a channel scan. Nothing. There’s a chance we just can’t get any OTA channels but we’re close to a city so I doubt it. And we’ve gotten them in other locales using the antenna. Is there anything else I should do? Does the short coax jumper remain connected to the two coax plugs? Thanks!
