4-way beverage antenna system CLASSIC CTRL & BI-DIR 150Ω PL
This antenna system consists of 2x Bi-dir beverage sets, 4-way antenna switch and controller.
485.00 € (without tax)
This antenna consists of 2x Bi-dir beverage sets, 4-way switch and K9AY/4-way controller. That all allows you to have 4 directions beverage antenna system with only one coax line from field to the controller. Controller have got Bias Tee (AC/DC), HPF (kill AC noise), internal PCB with 3 BPFs, preamp and protections. There is also RX/TX RF switch for TRX which does not have input for RX antenna.
Main functions
