Re: [Repeater-Builder] New Repeater Desense Problems

Additional accuracy can be obtained by providing a 50 ohm load for the generator. This can be accomplished by connecting the center of the ISO "T" to the center of the unmodified "T" to form an "H" configuration. Then connect the generator to one end of the unmodified "T" and a 50 ohm load

RE: [Repeater-Builder] New Repeater Desense Problems

John, In the cases I have seen, an "Iso-Tee" is constructed by removing the center pin in the offset side of a UHF "T" connector, grinding it down until it is flat with the insulator surface (add a notch so you can re-insert with a screwdriver) and reinsert the pin into the connector. This pro
