HJ1212/HJ1278/HJ-D----Weatherproofing kits for BTS antenna feeder system



Three items available in this series:

HJ1212 : closure for antenna---to---1/2" feeder cable (jumper cable)HJ1278 : closure for 1/2" feeder---to---7/8" feeder cableHJ-D     : closure for grounding kits



Antenna feeder system is an important part of mobile BTS (base transceiver station). The installation and maintenance of antenna feeder system will directly influence the mobile communication quality and signal scope.The antenna feeder system is made of three parts: antenna, feeder, and connector.  Here, the protection of the connector is especially crucial. Our product is designed for this need.It is a new generation of product designed for quick sealing of antenna feeder connectors in mobile BTS. It seals completely irregular connectors and corrugated cables in mechanical sealing box to guard against the corrosion of moisture and salt fog and protect the antenna feeder connectors from stretching, twisting and knocking.  The housing contains an innovative gel material.


1, Fast

With special design of embedded seal pin, the installation and dismantlement can be done in a few seconds.Any non-professionals can perform the operation work and provide standard construction maintenance.

2, Economic

Over 10 years of service lifeRepeat application, reduce the maintenance and repair cost greatly (material cost, man hour cost)Reduce the economical loss of bad antenna feeder adaptor seal resulted from non-standard human factors

3, Reliable

The protection box, completely separating the adaptor from external environment, passes the most strict waterproof test and low-high temperature test, ensuring the stable and reliable electrical performance of cable and adaptor.The housing is by reinforced design with high performance engineering level macromolecule polymer, which greatly reduces the loose caused by wind load or vibration, reduces and proofs vibration, and reinforces the adaptor.Strong weatherability, resistant to ultraviolet radiation and impaction

4, Safe

Easy installation and dismantlement greatly reduces high-altitude operation time and makes the work safer.


Comparison with original rubber tape:


Closure Box

Rubber Tape

Operation difficulty level

Very simple;  Don't need training on operation ; take some seconds to finish the job

Complicated; Require good operating staff; take much time

Protection Specification ( waterproof / moistureproof / salt mist resistant / high & low temperature resistant / UV-asistant/ age asistant.)

Good; Apply to many international standard.



10 years

1-2 years. The tape always becomes old and crack in a enviroment with high sunshine and temperature change.

Times of Using

Many times. Reusage.

One time

Tower top operation safety.

Easy installation. Shorten the operation time on tower top

Long operation time on tower top

Maintenance cost

Low; Reusage and easy installation

High; One time use; Cause connector damage
