Good to know

A booster strengthens an existing outdoor signal rather than creating one, so results vary by location. This is an FCC-certified consumer signal booster; as required for all U.S. boosters, register it with your carrier after setup (free). Backed by a 30-day money-back guarantee and a 2-year warranty.
