My bet is, you will blow the Pre-Amp.
You have to separate those things!

        ER... um... maybe.   Even Wellbrook says one should
        locate it away from strong transmit antennas to
        avoid overloading the receiver input.

        I think the correct answer is that it all depends
        on how well you isolate the receiver input from
        the transmit antenna and whether or not you use
        a separate receiver from the transmit radio, and
        similar considerations.  SO2R installations have
        similar issues - sometimes guys use a "front end
        protector" as is reviewed in QST this month, and
        other guys use a "time sequencer" to kill the \
        antenna when transmitting, tied to the PTT line
        and still others use a separate receive-only
        antenna input on the rig, as is available on the
        Omni VII, but not the Eagle.

        Yep... This COULD be a serious concern if not
        fully thought out.
        

        BUT YOU COULD TRY IT AND SEE HOW YOU LIKE IT
        AS A RECEIVE ONLY ANTENNA AND DEAL WITH THE
        TRANSMIT LOGISTICS LATER...

                I know SWLs often use hula hoops ...
