The Wilson Panel Antenna is a 50 Ohm outdoor mounted antenna used to pull in existing 3G and 4G LTE signals from your nearest cell tower source. This antenna is designed to be mounted on the inside glass-surface of your window facing the outside of the building towards your nearby cellular tower. It is a viable choice when a typical outdoor antenna (Omni or Yagi) cannot be easily mounted on the roof or high exterior wall. It is suitable for apartments and condominiums with limited exterior property modification access. It features up to +10.6 dB gain.
