This indicates it has poor directional gain and will under-perform other antennas. | + | **IMPORTANT:** do not buy an antenna that claims to be omnidirectional or claims to have 360 degree performance.

| - | IMPORTANT: do not buy an indoor antenna with a built-in amplifier or one that requires power to operate (this indicates a built-in amplifier). The HDHomeRun has a built-in amplifier – using an antenna that also has a built-in amplifier can make reception worse and may result in fewer channels. | + | **IMPORTANT:** do not buy an indoor antenna with a built-in amplifier or one that requires power to operate (this indicates a built-in amplifier).

| Amplifiers are generally only useful with a rooftop antenna where you need to split the signal to many devices or you have significant cable lengths. A typical install with a good rooftop antenna at 45 miles split 2 ways will generally not require an amplifier. | Amplifiers are generally only useful with a rooftop antenna where you need to split the signal to many devices or you have significant cable lengths.

| - | 55-65 miles: Use a large outdoor antenna mounted on a mast on the roof. | + | |
| - | 45-55 miles: Use at least a mid-size outdoor antenna mounted on the roof, or a large outdoor antenna mounted in the attic. | + | |

| - | 0-30 miles: A well designed indoor antenna will generally work. | + | |
| - | If you need VHF support look for a well designed indoor antenna with VHF support. An indoor antenna with VHF support will usually feature telescopic elements that you pull out to full length similar to an antenna on a portal radio. | + | |
