Detailed Product Description

Grounding Block

Features:   

    Technicians use Groudning block barrel connectors to link coaxial cables together within satellite, antenna and, cable television systems. Often, little thought is given to the F-81 used and things tend to work as expected. Satellite systems in particular, use high frequency signals. As satellite services increase offerings, so too does the bandwidth of the satellite system to transport these services. As bandwidth is increased, higher frequencies are employed to transport additional video channels and this challenges the integrity of the F-81 connector!

   The familiar F-81 90 degree connector is a small threaded coupler with a PVC insulator surrounding center-conductor contacts. The body is generally just long enough to couple two F-connectors. The smaller size reduces the cost of the product. This type of F-81 provides acceptable performance in broadcast television (antenna systems) and cable television installations. Satellite systems however employ higher frequencies and use of the lower-cost F-81 connector in these systems degrades performance.
