The easiest solution would be to use a relay.
For 10Mhz you don't need to worry about using an RF relay.
You may need switching delays to make sure you don't blow
up your receiver.
A relay will take a signifiant fraction of a second to
switch over, might not be suitable for your application.
100volts is a bit high for PIN diode switching, perhaps there is
a lower impedance point before you matching network
that is a better place to switch.
