Water Proof Treatment 

 

The water prevention sealing for the outdoor jumpers and the 

feeder grounding clips of the antenna feeder system is an important 
part of the antenna feeder installation. During the installation process, 

must use waterproof tapes properly to ensure the quality of installing 

the antenna feeder system.  

 

Connect and seal the 1/2'' jumper and the feeder as follows: 

1.  Connect and lighten the antenna jumper and the main feeder 

connector 

2.  Make water prevention treatment on the connectors in the 

following steps 
i.  Wrap the waterproof adhesive tapes from a low position 

where the connector is connected and wrap them about 
200 mm to fill in the low-lying parts of the connector, as 
shown in Figure 48.  

 

 

ii.  Extend the adhesive tapes to double their length when 

wrapping them. The direction of wrapping  must be the 
same as the direction of screwing the feeder connector, 
in case that the feeder connector may be loosened during 
the wrapping process.  

iii.  As shown in Figure 49, wrap the adhesive tapes layer by 

layer and then wrap them again in the reverse direction. 
The upper layer must cover the lower layer by about 1/3 
to avoid water penetration. Finally, wrap them layer by 
layer again in the reverse direction. Wrap the tape with 
three layers without any cut in the entire process. Wrap 
the tapes around the feeder connector till they protrude 
about 20 mm from the feeder connector.
