Useful interface

I have these SAT F-connector set as an alternative to an antenna socket. By connecting the can some originated in DB loss. So I tried it with the connector. On the receiver side, you can work with the set F connector on the socket side I've also put a plug and set this connector between. With box I had a signal strength of 47% at 90% quality. After conversion to joint 62% signal strength and for little money and a little work. Very useful part so.
