Maybe to vehicle specific, but I get no responce at bimmerboard.com

I have bought the bumper antenna for E46 cab.

I want to use it with USB TV for my PC.

Goes into car like this: (left side)

Do I also need an amplifier, or is it maybe built into the antenna? It is supposed to be connected to a VideoModule.

In case its got inbuilt antenna amp the Videomodule is supposed to power it thru coax.

If someone out there has got a Video module could you please check if there is a DC signal on the coax input? And what voltage in that case? (probably 5V)

If the antenna (it is actually 2 antennas, one of each side of the bumber) has got integrated amplifiers I need to power it, and combine the signals to my USB TV.

I have found a combiner but what about DC power?

Thoughts on this? I need a helping hand!
