>> ... Is there an after-market antenna worth looking at for this little HT?
If it is the reverse SMA that many of the Wouxuns use, then you are limited to the Wouxun 17" whip - available at Powerwerx.com.
But if you purchase a BNC-to-Wouxun antenna adapter, the world of aftermarket BNC antennas opens up to you.
"Better" means longer, in this case. TThe 17" flexible whips from Pryma (RD98-BNC) and others arew better performers.
