ICV-IV |
|
Applications: The ICV-IV antenna is designed for fixed stations and is suitable for skywave propagation for medium to long range circuits. It can also be used for ground-wave circuits up to approximately 100 miles. It is well suited for shore-to-ship communication circuits. Features: The inverted-cone vertical antenna has similar RF characteristics as the VOBA antennas. ICV curtains in contrast to VOBAs are supported by six wood poles instead of a single vertical tower allowing for more compact installations. Characteristics: The ICV-III antenna is a broadband fixed station antenna. All materials used in construction have been field proven and subjected to rigorous environmental testing. Equipment Supplied: Prefabricated alumoweld curtain, guys, base insulator, embedment hardware, ground screen, antenna matching unit, and spare hardware. Optional Equipment: Repair kit, repair tool kit, wood poles, and spares kit. Coaxial cable, connector adapters and mating adapters. |
