The Waveform Wideband Log Periodic Outdoor Antenna is a high gain directional antenna. It offers 10 - 11 dB of gain across all wireless frequencies (Voice/3G/4G/AWS/WLAN) from 600 MHz up to 6000 MHz. The antenna is made of white ABS plastic. It measures 440 × 205 × 60mm. The Waveform Wideband Directional Antenna needs to be set up pointing in the direction of the cell tower. We recommend it for situations where existing outside signal is weak, and you only want to boost coverage for one carrier (or if more than one carrier has a cell tower in that direction). If you need to boost signal coming from different directions, it is possible to set up more than one log periodic antenna. Contact us for more help with this.
