The Biconical VHF – UHF Broadband Antenna VUBA 9117 offers a a flat gain characteristic in the frequency range 150-1000 MHz. The directional pattern is circular in the H-plane and”8″-shaped in the E-plane, similiar to dipole patterns. A typical application for the VUBA 9117 is the fast and convenient broad band evaluation of the actual site attenuation.
