First of all, you want to know the range. If you’re homesteading and you’re far away from radio towers, you’re going to want at least 70 miles of range (which is why the models we reviewed are from 70 miles and up). You want to account for about 10% of that range being choppy, so try not to meet the full demand if possible.
Next you’re going to want a motorized 360 degree pivot system. Antennas aren’t all-powerful, and we know that weather and heavy clouds can restrict our viewing pleasure. With a 360 motor, you won’t have to hoist yourself up on the ladder and manually adjust it.
Some arbitrary things will be the amount of coax cable you get, or the height of the mounting pole. Those can all be DIYed to perfection, so don’t put a heavy focus on those. Instead, you’re going to want to look at the maximum streaming potential, such as HD or 4K, and how many units you’ll be able to run off of a single antenna.
Last but not least, we want these to survive in the rain and wind. Pay attention to the mounting bracket system, and the overall material build of the antenna and mounting pole itself. You don’t want a measly 20 MPH wind knocking it down or bending it. Part of the responsibility comes down to what you’re mounting it to and how it’s done, but starting with a sturdy pole is half the battle.
