  • Questions & Answers
    1. Can I get a configuration for a Dual Antenna Array that has VHF (138 – 174 MHz) for each exposed Dipole? The exposed dipole should be one (1) element each. The antenna configuration should be Heavy Duty and meet Palm Beach, Florida Wind Speed requirements (150- 170 MPH). The antenna gain should be minimum 2.5 dBi.
