A phased vertical array on 20 meters can give you a boost in gain and directivity on this popular amateur radio band. Bob (VK5FO) gives you a "walk through" of this antenna and a description of the end-fire phased array consisting of 2X 1/4 wave elevated ground plane antennas. This antenna would make an excellent field day or contest antenna.  Most of the materials can be bought at the nearest home improvement outlet or neighborhood hardware store.

N7EAA's 65 foot vertical for 160M. Post #1255.

Image
If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=LXcInIk1fGo. Here's a dual band top loaded vertical antenna that covers both the 160 meter and 80 meter amateur radio bands.  For this project, N7EAA used a MFJ pipe for $200, galvanized steel electrical fence wire, and inexpensive poly rope for guy supports.  You'll probably need some help assembling and erecting this antenna. Like all vertical antennas, you will need a good ground radial or counterpoise system.  In this video, N7EAA attaches his ground system to an aluminum plate at ground level.

Homebrew antenna , 10-40 meter loop antenna. Post #1253.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=3T1LOGahiwY. Here's another HF loop antenna idea if you have some trees or tall supports in your backyard.  Marcus Schrader built this full-wavelength 40 meter loop (143 feet/43.59 meters) and suspended it 20 feet/6.09 meters above ground using a few trees in his back yard.  He uses a 4:1 balun along with a length of 450 ohm ladder line to feed the antenna.  Marcus uses this combination with an antenna "tuner" to cover 10 through 40 meters.  As you can see from the video, the antenna is fairly "stealthy".
