One very easy way to do it is to key a small high speed SPDT relay with 
the "QSK" signal of the Jupiter.   The realy common terminl goes to the 
Jupiter, the NC terminal to the Beverage and the NO terminal to the 
Yagi.  In receive, the relay will connect the Beverage, in transmit it will 
connect the yagi.  By adding a toggle switch in the relay coil line, you can 
manually select one or the other for both transmit and receive, although 
you probably would not transmit on the Beverage.  A time tested relay 
that will easily handle the 100 watts and key in less than 2.5 mS, which 
means it follows the full break-in keying, is the Radio Adventures BK-173 
relay.   It is used in the Vintage T/R Adapter featured in the ARRL 
Handbook the last several years.
