Cell Phone Signal Booster GAGBK YBA70

Type: Cell phone signal booster / amplifier kit
Brand: GAGBK
Model: YBA70

Key Features

• Improves weak cellular signal indoors by capturing outdoor signal and rebroadcasting it inside.

• Includes a directional outdoor antenna to capture stronger tower signal.

• Designed for 4G LTE and some 5G bands depending on carrier compatibility.

• Works best when some signal exists outside (boosters amplify signal—they cannot create signal where none exists).
