If you want a simple, inexpensive 2 meter Yagi Antenna for home or portable use, then this project from Tony Breathnach (EI5EM) is for you.
Tony shows us how to design and make this basic antenna with locally available parts.

This is post 2783 in a continuing series of simple ham radio antennas.
Here are some comments from Tony:
This video clip describes my build of a four element 2m portable amateur band Yagi antenna. The antenna has a single reflector and two directors along with the driven dipole element. For the boom, I used a scrap offcut of 25mm plastic (cable) trunking with a clip-on lid. I used 1,000mm lengths of 4mm threaded steel bar for the elements
The video shows detailed photographs of the build followed by testing at two locations for transmit and receive. Full dimentions of the element lengths and spacing are given. This is a simple, inexpensive and easily repeated home construction project for the radio amateur.

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.
