well i've only been in the headend once. i spent about 2 hours tightening fittings so i didn't even look at the problem. it wasn't a problem when i was down there. they don't come in through an amp but they do go out of course. since it wasn't a problem i don't know the output. the property is four hours away and they maint supe can't provide me with this info. actually i did hear there was an amp on the ant. so if thats true then yes. sorry.
i will try the new mod. also plan on changing all the fittings too. some of our headends have bad fittings or fittings that are hand tightend. thanks for your help. i'll probably leave on wed. to look into the situation. thanks.
