VHF 147-156MHz omnidirectional antenna
Description
The Atel Antennas omnidirectional antenna for the 147-156MHz VHF band is designed for uniform and efficient coverage. Its 50? impedance, 2dBi gain, and VSWR of less than 1.5 ensure reliable performance. The 78° -3dB beamwidth and vertical polarization provide optimal 360° coverage.
The structure is made of a glass-epoxy mast, an ENAB-44100 aluminum alloy support, and stainless steel hardware, ensuring strength and durability. The antenna withstands winds of up to 160km/h and temperatures between -40°C and +85°C. With a length of 1410mm and a weight of 1200g, it is equipped with an N-female connector and can be mounted on Ø33-60mm poles. It also features a DC grounding system and a condensation drain hole:contentReference[oaicite:4]{index=4}.
