380-520MHz Fibreglass 6dB Omni Colinear

380-520MHz 6.0dB Colinear


The CL4-6 is an omnidirectional 6dBd gain colinear antenna with all welded internal elements which minimise the generation of intermodulation and spurious products. Through the use of internal DC grounding and radiating elements enclosed in a heavy duty fibreglass radome, the effects of precipitation static and lightning are reduced. The radome is bonded to a marine grade stainless steel mounting tube.
