136-175MHz Fibreglass 3dBd Omni Colinear

136-175MHz 3dBd Gain Colinear


The CL3-3 is an omni-directional 3dBd gain collinear 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.
