Wi-Ex zBoost zForce YX240 Cell Phone Signal Booster, Dual Band 800/1900 MHz, Auto-Shutoff

The Wi-Ex zForce Cell Phone Signal Booster extends an in-vehicle Cell Zone. The dual band unit captures the signal outside of your car and amplifies it on the inside for a stronger "hands-free" signal. The unit incorporates a cradle and works with both 1900 MHz and 800 MHz phones - most carriers and phones. The product consists of a bi-directional amplifier unit housed in a sturdy, lightweight cradle. The amplifier connects to the vehicle's 12 V power through a supplied Cigarette Lighter Adapter (CLA).
