When connecting data and power cables to radars in harsh or corrosive environments Navtech recommends the use of Chesterton© 740 as a product to protect the military specification connectors from corrosion.
This is a recommended best practice. Failure to apply the product could mean extra down time for radar and longer field time for engineers.
Over extended periods of exposure to the harsh environments that radars are often installed into the connectors can become corroded making their removal difficult, even causing damage to the radar in extreme cases.
