VHF 140 174MHz 1/4 mobile antenna
Description
The Atel-Antennas VHF mobile antenna covers the 140-174MHz band with a 1/4 mobile design, perfect for automotive installation. It offers standard 50? impedance, power up to 50W, and a gain of 2.14dBi, ensuring high signal quality with omnidirectional emission and vertical polarization. The robust AISI302 stainless steel body, combined with resistant components such as the self-extinguishing Moplen cap and Kraton gasket, ensures durability and reliability even in extreme environmental conditions from -40°C to +80°C.
The antenna uses a 4500mm RG-58 coaxial cable with a capacitance of 100pF/m and is equipped with a cutting diagram to adapt the tube length based on the operating frequency, maintaining a VSWR of less than 2.0. Dimensions: base diameter 43mm, base height 40mm, rod 500mm, weight 350g. Mounting hole Ø24mm. Ideal for radio amateurs and professionals who need a versatile and high-performance VHF mobile solution.
