2 VHFs sharing 1 VHF antenna

I have an Apelco VHF mounted in the nav station with a remote speaker in
the cockpit. A Raymarine handheld is kept near the helm. Of course the
handheld has nowhere near the range of the fixed VHF below. Instead of
replacing the [perfectly good] Apleco VHF, I would like to install a
second fixed VHF at the helm connected in such a way to share the mast
top antenna.

Is there an adapter or junction/splitter type device which will allow
both VHFs to be on at the same time (not transmitting, of course) and
share a common antenna without manual switching or other intervention?

Seeing all the responses makes me wonder if this question is too simple
for me to understand. Since you say you want to install a second radio
anyway, why not just select one with a remote mic option to replace your
existing radio? That would give you the two stations you seem to be
looking for while using just one antenna.
