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!
