Thanks to Mike (M0MSN) for this "Slim Jim"/"J-Pole" antenna idea.
This dual band (2m/70cm) antenna is easy to build and will give you a bit more gain than a 1/4 vertical whip.
This variant of the popular "Slim Jim"/"J-Pole" antenna is suitable for both home and field use.

Here are some comments from Mike (M0MSN):
HAM RADIO: Easy SlimJim / J-Pole Dual band Antenna Build for 2m/70cm, Thanks to a book I purchased many moons ago, I have found the perfect way to pass a rainy day. make a 2M / 70cm Slim Jim or J-Pole. Not just the standard J-Pole but one that uses a decoupling stub so that you get the maximum power on both bands..........
You need:
1.5M of 300 Ohm ladder line
15cm /6 inches of RG176 or RG316 coax
and that's it, Bobs your uncle.
Many thanks

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.
