Hi all,

Was just wanting to know if people can shed some light... I bought a TV Signal Booster for my car TV obviously so i can watch TV while waiting for the mrs.. anyways... my questions are:

1) Why would it require DC-12v (-ve)??
2) Are others setup like this?
3) Is there a way I can invert it to DC+12v (+ve) with a seperate in-line circuit for the power lines?
4) Or is there a kit available in the market that i can build to combat this?
5) Can I simply replace the PNP transistors inside to similar NPN??

At this stage from my limited experience and checking out the components and circuitry, QUESTION 5 seems unlikely but am just making sure.

This is sort of a complex question guys so please no telling me to "reverse the polarity" coz it's no-where near the same thing... only want advice from persons who actually work in electronics. Even someone who repairs amplifiers or car audio repairs would be of big help.
