4220.06 - TETRA 6dBd Colinear Antenna

The 4220 Series colinear antenna is designed for demanding applications where a durable and high performance colinear antenna is required. The centre fed dipole design and feed network gives a stable radiation pattern across a wide bandwidth, and allows tilted beam designs to be effectively employed without large pattern distortions. High quality materials and manufacturing techniques are employed to ensure that the antenna has excellent intermodulation performance, an essential characteristic for TETRA and other multi-channel communication systems. The antenna has been designed to withstand lightning strike and has a conductor through it’s centre to allow a finial to be fitted to it’s top cap, and is supplied as standard with a 7/16 female connector.
