If the antenna device uses an electronically adjustable antenna, the waterproof treatment method is slightly different. The electronically adjustable antenna is generally connected to the AISG interface of the RRU through the electronically adjustable antenna controller of the RCU. On the RRU side, the AISG cables do not need to be waterproofed.
On the side of the ESC antenna, the two ends of the RCU adopt different waterproofing methods:
1. The joint where the RCU is connected to the ESC antenna adopts the "1+3+3" method for waterproofing.
2. Wrap two layers of anti-ultraviolet tape at the joint where the RCU is connected to the AISG cable. Note that the first layer of anti-ultraviolet tape should be wound from top to bottom, and the second layer should be wound from bottom to top. That is to say, the outermost layer of tape must be wound from bottom to top to prevent water droplets from penetrating.
