Antenna AC MARINE CX4b
CX4b is an omni-directional dipole antenna. CX4b made of high quality materials in order to prevent galvanic corrosion. Radiating elements are made of brass. CX4b has the same 
robust design as well as all other products antennas AC MARINE, thus withstand harsh environmental conditions, both at sea and on land.
Vertical radiation pattern for an omnidirectional antenna at the center frequency. It shows that the antenna has a gain of 0 dB near a horizontal plane.
