Passive antenna meaning

WebPassive systems, also known as cell phone signal boosters or bi-directional amplifiers (BDA), use a donor antenna ( omni or uni-directional) to send and receive off-the-air RF signals from the signal source – generally nearby cell towers. The signal picked up by the donor antenna is sent to the repeater via coaxial cables for boosting.
