Antenna F1 VHF has less gain than F2 VHF, but in contrast to the popular antennas of Anli and Diamond companies it possesses more reliable design - its diameter is 2 times larger, the case made of glass-fiber material is more thick, the mounting is massive and the counterpoise are replaced for the cutting balancing barrel hidden inside. Thus, it is not risky to install antenna F1 VHF in most severe climate conditions, "hanging" on it the data transmission or any professional duplex communications.
