Yes, it is, and a fairly large transistors are used, along with
some protection. Observe voltage/current limitations given in the manual
(13.8 V, 250 mA), and do not forget the protection diode at the realy coil.
No additional components are needed to connect any number of outputs in parallel.

Actually, it's simpler than that.

A plain SPDT coax relay can be used, driven by, say 160..30 m outputs
in parallel. Connect 160..30 m antenna to the NO connector,
and the other antenna to the NC connector.
