I have always been a fan of full-wave HF Loop Antennas, especially when I can "go to the field" and hang lots of wire in trees and other tall structures.
In this video from K7SW, we get a full start to finish discussion of designing, building, testing, and using a full-wave antenna for the 80-meter Amateur Radio Band. Of course, you will need a lot of "open space" for this antenna, but the advantages far outweigh the disadvantages of such a large antenna.

Here are some comment from K7SW:
On this camping trip, I take the parts required to setup and test this 80 meter full wave loop antenna. Starting out with 288 feet, I trim this antenna to 280 for my location. The tree supports were a max of 25 feet at this test location for POTA K-4397 I take some measurements and get to use this antenna to see if it can be of use to me camping or for use as another antenna at home. This antenna could work as a permanent setup or on a field day station setup.
