Holland G-F81F* Universal Coaxial F Splice Connector
Appears on the DISH Network Approved List!
has advanced the traditional F splice technology with a patented design offering a higher level of electrical and mechanical features. The advanced features provide increased return loss beyond 3 GHz, twice the pin contact area and increased holding force for higher current handling and greater reliability. This F-81 is 15.4 / 8.6 mm. (long side/short side) allowing Feed-thru Wall-Plates and Bulk-heads up to 5/16 in. and still accommodates the F Connectors. You can select the washer and nut needed to fit a wall Plate from the accessory box above. Use on Satellite TV and Other Critical High Frequency connections.
An adapter (or adaptor) is a device used to match the physical or electrical characteristics of two different Connectors so that a connection may be made between them and the Equipment You desire to Cross-Connect. Most Connections for Video and RF (Radio Frequency) Equipment is 75 Ohm in Characteristic Impedance. Radio and Microwave Frequency Connections Passing High Power Require 50 Ohms. A Majority of the Adapters offered Here are 75 Ohm. However, with the High Quality Dialectric Found Surrounding the Interior of the Mating Connection, Low Power Usage, and Transition Impedance Matching of Like Characteristic Impedances, Resulting Mis-match of 50 Ohm use woiuld be so Low as to be Considered Negligible.
