Hi,
I'm trying to hook up an active antenna that needs 5V at 30ma to be fed thru the coax, to a tuner that doesn't provide that power. I'm assuming I would be able to just hook up a 5V supply (from a USB socket in this case) to the coax, with a capacitor between the centre conductor and the tuner input.
Will this affect anything adversely? Is there a better way to do it? I wouldn't expect the weak RF signal to affect the computer much, but who knows. :)
The antenna will be mounted indoors near a window so lightning or surges shouldn't be too much of a problem.
I thought of modifying a 2-way passive splitter for this purpose. What cap should I use?>
I'd like to receive VHF and UHF, from 170-230MHz and 500-600MHz. It's a digital TV receiver if that makes a difference.
thanks!
