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...

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aeNHIQ_j4Dk This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH). 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.

Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise. Why not equip your bicycle for 2 meter/70 cm mobile operation? In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station. The project is straight forward, simple, and gives you emergency communications while you peddle down the road.
