Equipment: Wired, carrier-specific amplifier, such as the
Signalwide ClickitBase ($230; signalwide.com), connected
to your phone
Installation tips: The antenna doesn´t have to be outside, but it will work better if it is. Inside, your phone attaches directly to the amp with a
handset-specific cable or a mini-antenna, called an inductive coupler, stuck to the handset. Since the phone is tethered, use a Bluetooth headset to roam around the house.
