Jim, you are correct when you say there is no DC voltage on the "TV 1/2" output F-81 connectors and the Park Cable input F-81 connector since the DC power needed by the Roof mounted amp is shot up the roof antenna feed only.

That being said, the power switch serves another function besides turning on the roof amp. It also electronically switches the inputs to the TV1 and TV2 outputs. That circuitry could be the interference being experienced.

i would have to see a schematic or tare into it to see how they are doing it. i'm looking at the switch as switching between the park and ant. the output of this switch being fed into a splitter: one output of the splitter fed to tv1 at the plate and the other fed to tv 2. if this is the case, the output of the splitter should be able to be used as a feed to go to the other set.
if it is going thru a switch (a ppt circuit comes to mind on a cb), the signal won't back down that.
in his case, he had the signal and needed a better signal. an amplifier placed between the dtv output should upgrade the signal. i'm thinking that the output from the dtv receiver is not great enough to overcome the distance plus a splitter.

in my case, i did not want to loose the ability to use the ant so i chose an external wireless transmission system (~$50) that would transmit the audio, video, and ir signal to a second tv. that set could be moved around.

for a greater expense, dtv has equipment that will combine the ant and dtv feed (between dish and sat receiver) and another device that will strip of the conventional antenna signal at the set.

my first suggestion to diamondjindustries should have been to check his connections: make sure cables are making good contact and tight. then go from there. it sounded like he had an outside connection factory installed for the purpose of adding another tv. i'm hoping that he wasn't referring to the park connection.

I got the impression (maybe wrong) that he was using the Park Cable connection as an output to feed his TV.
If he is not, you are 100% correct.

I found a IR system at radoi shack it works great.

Thanks
