Here's another great portable antenna idea from Australian radio amateur Peter Parker (VK3YE).
In this video, Peter describes "a simple vertically polarized beam" for the 15 meter Ham Radio band (21 MHz.). This antenna is suitable for both home and field use.

Here are some comments from Peter (VK3YE):
Beams can be heavy and bulky so are rarely used by HF portable operators. But not this one! Described is a simple vertically polarised beam for 21 MHz. With a quick to rotate wire reflector and easily-fed off-centre driven element.
Thanks to Nik VK3ZK for the test.

This antenna is quite similar to (but mechanically easier than) the Vertical Dipole Array. More on those here: https://oh1tv.fi/VDA.pdf The discussion here is also worth reading: https://reflector.sota.org.uk/t/vda-t...

Here's an interesting antenna design for radio amateurs exploring the 630 meter and 2200 meter amateur radio bands. This classic antenna is basically a top loaded vertical designed for frequencies below the standard broadcast band (472 kHz and 137 kHz). Even though this antenna is inefficient, a digital signal using the FT8 protocol should get you some contacts. Good luck!

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.

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.
