CATV Anti-theft Filters

The male end F-type connector of this kind of filter, because of its special design, must be locked or loosened by using a special wrench to prevent it from being arbitrarily removed, so it is called "anti-theft" type filter.

Soontai's "anti-theft" type filters have been approved and widely used by many MSOs.

This "anti-theft" type filter can be any of the Soontai 1 series of LPF, HPF, BRF, BPF, WF, DBF, TBF, ... filters. Please refer to our filter series.

To order this "Anti-theft" filter, just select the type of filter you need and provide your specifications. Then tell us that the filter need with an "anti-theft connector", and how many piece "anti-theft wrench" you need, it's that simple!
