The first is theoretically possible (there is a device called an OCAR (on
channel active repeater) which is literally 2 antennas and an amp). Trouble
is you'd have to home brew it (== illegal for our purposes)...
As for passive, you lose 32 odd dB in a passive repeater, before any other
losses can be considered... (I don't know the details, but there is that
constant in the equations). Might be workable with a couple of high gain
dishes in strong signal areas with some obstructions.
