Herk, this is from the desc. Looks like it does have fm? I have the same and its terrible. Maybe a email to them is due.
Soooo, I just read the installation instructions on that page and while it says "TV/FM" in the subject line, there is no mention of installing a radio in any of the directions. An FM "trap" is required to suck out the 88 to 108 Mhz band and route it to the radio.
Since there is a warning about installing any splitters in the down lead, if there is an FM "trap" it would have to be located in the TV2 output.
If this is the case, you are correct that the power to the switch must be on to get a roof signal through to TV2 and the downstream FM trap.
or something like it, is what you are looking for in the TV2 output line.

is an interesting read and could be the cause of your crappy FM.
