|Good Ol' Block 21...|
I know there's more intelligent (& cheaper/lighter) ways of dealing with stray RF than throwing more splitters, combiners, sharkfins and preamplifiers into your rig. In doing so, you are essentially re-designing the front-ends of receivers that have already been very carefully designed. But this seems to be the popular trend, based on general lack of understanding, and I'm sure the equipment vendors don't mind at all. Of course, I'm often wrong, but certainly never in doubt.
