    So is this possible and what do I need if so?
    Mobile station two dual band vhf/uhf(extended receive transceivers) presently connected to separate dual band antennas. I want to clean things up a bit and see if its possible to connect both radios to one antenna.
    Naturally I wont transmit on both at the same time.
    I see SO2R boxes for HF but hadnt seen anything broad banded for the nosebleed frequencies.
    Thank in advance

    MEH, I googled the situation and it doesnt appear possible without relays, switchboxes, and the like.The consensus is its cheaper to have the second antenna..

    It cannot be done safely. Separate antennas for one radio? A-OK with the right duplexer. Two radios on one antenna? Only if they're on different bands, and the appropriate diplexers are used. Otherwise.... Pufff!

    I see no reason you could not use a coax switch to alternate between radios. I use a coax switch at my QTH for swapping around various antennas. As others have mentioned you do not want to coax from the radios connecting to each other.
