Antenna A10-23-H is specially designed for operate in the top sub-band of an amateur band 23 cm and intended for work in structure of a repeater together with duplexers MDF1-6-23 or DPRE4-6-23.
The antenna is constructed on a principle transposition 1/2λ coaxial radiators. Its sizes are optimized for achievement of the maximal gain along horizon, that effectively affects range of repeater. Therefore its working strip makes only 30 MHz. For operate in the bottom site of 23 cm band 1240-1270 MHz ask antenna A10-23L.
The complete set of the antenna includes convenient fastening with a collar from stainless steel. The antenna radom made from fiberglass. Antenna is earthed on a direct current.
