Radar antenna directly affects the performance of radar receiving and receiving. Good maintenance is very important for radar performance.
Often (semi-annual):
1. Clean the radiation outlet once (clean water, soft cloth, soft brush)
(2) Check that the waveguides and connectors are fixed and the cables are watertight across the deck.
(3) Paint the antenna base once, but don't Paint is strictly prohibited at the radiation opening, otherwise it will cause scattering and attenuation.
