Installation Proposal This transmitting antenna is intended to meet the requirements of maritime mobile services. It should find application wherever on account of extreme climatical and operational conditions the antenna has to guarantee maximum strength, stiffness, and reliability. It requires very low maintenance. The antenna mainly operates as a vertically polarized radiator with an omnidirectional pattern. Mechanical Specification Design The antennas consist of two sections, and the lower section with its seawater resistant cast aluminium base has a length of approx. 5 meters. The...
