I'd recommend not not buying antennas from ordinary retail outlets,
they'll sell anything that looks good in a shrinkwrapped box.  Look
here instead:

These are decent, and not expensive, we've used them before:

I saw some cheaper ones in there as well.  The ubiquiti bullets will
screw directly onto a female N-connector.  It's good to seal the
connectors too.

If you really are out in the middle of nowhere, you won't have a lot
of other transmitters to compete with.
