Wiring and preparation
4. Make a hole of at least 20 millimeters in diameter through the deck or bulkhead to run the sig-
nal cable. (To prevent electrical interference, do not run the signal cable near other electrical
equipment. Do not run the cable in parallel to power cables.) Set the cable through the hole.
Close the hole with the marine sealant for waterproofing. Failure to do so can lead to water
seepage and may cause equipment malfunction or damage.
5. Remove the shield covers in the radome. (RTR-057 has three shield covers, RTR-057A has
two shield covers.)
