RSB 0093 - drain hose at the bottom ???

[proasegler]

I have bought a used RSB 0093 Antenna as a replacement for my flooded one. On the bottom of the dome unit there is a small hole with a hose ?? coming out about 5cm. Is this made by the factory and what is the pupose? I also found some salt cristalls inside the dome. Should I be concerned? There is no corrosion on the electronics and wires so far. The dome cover and seal are like new.
Thanks, Peter

You must have gotten an older 1623 radar dome because the newer ones do not have a hose. The hose if the breather. You want to make sure that doesn't get bent over or closed because the dome needs to breathe via that breather vent.
