Hi Gene,

This has a good chance of working, even for a simple single element
antenna.

but I think that the losses through the coax cable could be
substantial.

You don't explain why, and an external antenna, up high can make a big
difference.

In order to alleviate this problem, I could put an in-line
amplifier just under the antenna.

This is also a good idea especially if the simple antenna does not
work well. More antennas probably will not give you as much gain as
the amplifier so if the simple antenna does not work, go straight for
an amplifier.
