If you're into antenna experiments, check out this video from Simon (VA7BIX).
Simon makes a good copy of a "fractal antenna" for HF testing. This unconventional antenna design is widely used in cell phones and some UHF television antennas.
In this instance, Simon's antenna was placed on 10 meters where propagation was poor for testing day. Simon will investigate his project when propagation improves.
Nonetheless, this antenna design has some promise, so stay tuned for Simon's update.

Unlocking the Power of Fractal Antennas! 🌀📡 | Fact or Fiction? #hf#antenna#hamradio
G'day Mates, this fun video is diving into the mysterious world of "Fractals" and the "Hilberts Curve" a series of infinite squares, and in this instance, what does adding 'fractal squares' do to the SWR to an ordinary 6ft piece of 3 inch metal tape? Let's watch and find out - wooohooo. Cheers and beers mates, and see ya on the airwaves soon.
ps. the band conditions on 10 meters were poor, so this was just an objective side by side comparison of what cutting the squares did for impedance and resonance.
THANKS FOR WATCHING MATES.

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.

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.

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.
