No. The 70 cm amateur band is around 440 MHz -- way above 160 MHz.
The marine frequencies would be closest to 2 meters, and not all that close.

I think a dedicated antenna is going to be simpler, cheaper, and work
better.



Sorry, my misprint, I meant a dual band 2M/70cm tuner.

Absolutely, a dedicated antenna is the best move. Unless you are trying
to mount an extra antenna
on a certified aircraft. Lots of paperwork and $$$. I was speaking to
the concept of using a HT marine
radio on an antenna "normally" used for aviation band, and already
installed in the airframe.
