The Diamond F-23 is a professional VHF antenna that is ideal for base stations, has very good gain and high quality construction. It can be tuned for maximum gain on a selected frequency from 144 to 174 MHz.
All Diamond's base antennas are fitted with a grounded radiator (minimum), which protects us from dangerous electrical static discharges. This is the key feature of Diamond's antennas that makes them stand out from cheap imitations.
Diamond antennas are made of high quality and durable materials providing us with the best possible performance and durability. The main tube of Diamond antennas is made of fibre glass, which effectively protects the active elements of the antenna. The base is made of reinforced aluminium and the short radii are made of stainless steel. The connector plug is integrated into the main antenna tube for better protection from dust, shocks etc. and all Diamond antennas are available with 2 clamps for easy mounting on our roof or balcony.
The F-23 covers operates from 144 to 174 MHz and the gain it offers us is 7.8dBi. It has an impedance of 50Ω and the standing impedance it exhibits is less than 1.5:1. Its height reaches 4 meters and 60 centimeters and its weight is 1 kilogram and 700 grams.
