John,
Since this is your first antenna, my first recommendation would be to find a ham or club in your area.
They may be able to give you a hand putting an antenna together.
Stay away from the magnetic loops, even the very experienced have a time getting them properly tuned
and they are very narrowbanded!
IMHO, your first antenna could be a 40M Inverted Vee (or Dipole).
This will give you local QSO's during the day and some nice DX at night.
You have 40 to 45m (131-147feet) to play with.
So, when you have worked all the DX in the world with the 40M antenna

You could take it down and rebuild it as a 130-135ft dipole fed with 450ohm ladder line
and work all bands 80-10, with a good tuner...
Maybe even feed one side (1/2) against ground and work some 160M.
