Your antenna is a private label Mohu Sky 60, a product that I believe to be a triumph of enthusiastic marketing but an abject failure at being a good antenna. The included amplifier isn't much better, depending on which version you have. The stupidity is compounded by putting the amp indoors, at the wrong end of the 30' coaxial cable. That's before it's excessive 25-26 dB gain on VHF (box says 15 dB), overload susceptibility, and the COMPLETE lack of any filtering above 45 MHz despite the marketing claims of some kind of filtering. Also despite the manufacturer's marketing, the antenna does need to be aimed. It's broadly bidirectional with HPBW of an estimated 60-70°. That means it must be facing broadside to the signals and that it will tend to reject signals arriving from the general direction of its points.
Since you've already preemptively eliminated the one type of system that would most likely do the job for you, you're going to have to determine what the minimum requirements (which stations) are going to be for a "successful" install.
