One antenna and multiple card

Is it possible to use one antenna with several radio cards? I figure it would need an amplifier to do so, otherwise the power would be reduced significantly. Anyone done this? Thanks,
David

Well I was thinking more a long the lines of numbers of antenae on my vehicle. I already have two large antennae for mobile phone and uhf radios. If i add another two, it becomes an antenna farm.... Thanks

In theory it can be done. Another bit of theory is that as soon as one of the cards tries to transmit one packet, it will blow up the receivers of the other cards. So you want to be really sure they are in receive-only mode.
