This should work OK as long as you keep a few things in mind. First, the quality of drop splitters ranges from ultra cheap garbage to good. If you want very good or excellent, find a used 550 MHz, 750 MHz, or 862 MHz Scientific Atlanta headend combiner. But depending on how many remote sites you have, these may introduce more loss than you want.
The isolation on a god drop splitter will be about 24 dB. That is, if you terminate all ports either with connections to receivers or with resistor terminators. Off the top of my head, I'd be a bit cautious of the potential for saturation of the splitter cores from strong VHF field of the repeater transmitter. Cheap splitters, or splitters made a few years ago weren't designed for high levels of RF. Their cores can saturate easily. If you can notch or passband the UHF feed, I'd do it. Using a preamp in line will provide the passbanding that you need, also. --- In [email protected], "Bob" <[EMAIL PROTECTED]> wrote: > > So, I was thinking (often a dangerous proposition)... > > If I want to run several UHF link receivers off a single antenna, > what's to stop my using a conventional TV splitter?
