Hello Chris,

I  have about 17 acres to play with,

That's very well suitable to play with!

  mainly woodland

Doesn't matter, no disadvantage.

  but with a 5 acre
field  and  a big front garden. I thought an aerial antenna would be a
none  starter  due  to  the voltages involved, so I'll be looking at a
ground  loop  for  sure.
Yes, do that! It is so easy to build up! No coils, no high voltage. It will have a high bandwidth and you can simply put the two wire ends into the shack and series resoante them there. 
  but I am going to need some basic advice to get going I am afraid

Don't worry.
I do recommend this ferrite core: https://www.buerklin.com/en/Products/Passive-Components/Inductors/Ferrites/Ring-core%2C-outer-%C3%98-x-inner-%C3%98-x-height-%3D-63-x-38-x-25-mm%2C-N30/p/84D258
