If you have a large open space for your next HF antenna, please consider this full-wave 80 meter loop antenna from Kevin (K7SW).
Fed with ladder line and joined with a balanced antenna tuner, you will have several HF bands to explore on your next adventure.
This 80 meter loop antenna is perfect for emergency communications via NVIS (non-vertical incident skywave).
Kevin shows how to build one of these impressive loop antennas and gives us several suggestions on how to support this project.

Here are some comments from Kevin (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.
Thanks for watching 73

The G5RV and its popular variant, the ZS6BKW, are popular multiband HF antennas for radio amateurs. In this video, members of the Stamford Amateur Radio Association W1EE, show us how to build a ZS6BKW antenna capable of covering the 80 to 6 meter amateur radio bands. Here are the guidelines offered by this construction team: "The ZS6BKW is the successor to the G5RV. It's a multi-band 80-6 meter wire dipole. ZS6BKW started with the G5RV and then conducted extensive computer modeling to increase the gain, flatten the SWR a bit, and smooth out the lobes. It's also about 10 feet shorter than an equivalent G5RV. The antenna must be fed with 39 feet of 450 ohm ladder line and also must have at least 70 feet of coax feeding the ladder line. The coax and ladder line together form a matching network that brings the SWR below 2:1 (

Bernie does an excellent job of explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV). Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use. The G5RV is an excellent choice for the 20 meter band. Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.

Don't let deed-restricted properties (HOA/CC&R) stop you from enjoying Amateur Radio. In this video from AC2RJ, we see how some well-placed trees, a camera tripod, a telescoping fiberglass mast, and a "V" antenna can get you on the air without a lot of effort. Add an antenna "tuner", a sturdy rig, such as the Yaesu FT-817, a microphone/cw key, and a simple grounding system, and you have a fully functional, nearly invisible ham station in your backyard.
