These simply refer to different antenna mounts.  The TNC and BNC are
larger mounts (the TNC being a bit more common on modern radios), while
the SMA is a much smaller mount, and is used on some Icom models (such
as the M1 and the M15) and on some Standard models (such as the
HX-250/255).  All of the telescoping antennas that I have seen have a
TNC or BNC fitting--thus the need for an adapter if you have a radio
with an SMA mount.  (BTW, depending on the nature of the adapter,
waterproofing the connection is fairly simple.  However, I suspect that
for most handheld waterproof radios the waterproofing of the antenna
adapter is primarily a *corrosion* issue, not a water penetration issue,
but don't hold me to that...you should look into this for your specific
radio.) 

Your Apelco 510 has a TNC mount, which means that all you need to do is
to buy an antenna with a TNC mount--there is no need for an adapter.
These are readily available from marine electronics stores.  Those who
own an Icom need to exercise care in selecting an antenna and/or
adapter, as Icom has produced models with all three types of antenna
mounts.
