If you want a basic two-element curtain array, try this "Lazy H" antenna from Hiram Vazquez. The "classic Lazy H Antenna" consists of two horizontally-polarized dipole elements which, under excellent conditions, can deliver up to 3.42 dBd over a standard dipole antenna.

Here's another great, innovative antenna project from Dave Tadlock (KG0ZZ). In this video, Dave takes us step-by-step through the design, construction, testing, and use of a simple 10 Meter Ground Plane Antenna.  Even though propagation on 10 meters is poor most days, the band will support good local contacts--perfect for informal nets and ragchews. Here some of Dave's observations: A 10 meter ground plane antenna that can be mounted on a mast or used as a ground mounted vertical antenna.

Thanks to W4AOX for this simple and helpful tutorial on how to design, build, and use a multi-band HF antenna. Although the antenna is designed for the 40 meter and 20 meter bands, it will work on the 15 meter, 12 meter, 10 meter,a nd 6 meter Amateur Radio band with an external ATU. W4AOX provides some general guidance and a materials list here: In this video I go through the steps to build a very simple, inexpensive multi band dipole antenna for the 40 and 20 meter amateur radio bands which can be used either at your home or in the field for off-grid emergency communications. Additionally, this DIY wire dipole antenna will also work on the 15, 12, 10 and 6 meter bands if your radio has an ATU or you have an external tuner. This exact DIY Dipole Antenna has allo

My 3 Favorite Antennas for Portable Ham Radio (HF)

Thanks to Johnny ("Signal Search") for this introduction to portable field antennas.  Johnny does a great job of describing his favorite "take with you" HF antennas. His list includes a homemade "L-Dipole Antenna", a Sotabeam linked dipole, and an end-fed wire.  These antennas are easy to build, fairly inexpensive, and completely portable. With a little creativity, these antennas can be used in deed-restricted properties (HOA/CC&R)...easy to erect and disassemble. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Do small tuned counterpoises work with HF vertical antennas?

Thanks to Australian ham Peter Parker (VK3YE) for this unique elevated counterpoise system for his HF vertical antenna. According to Peter, the tuned counterpoise works fairly well.  You may want to use Peter's idea if your HF vertical has a poor ground radial system produced by limited space or deed restrictions. Of course, Peter's location on the ocean shore does a lot to enhance his signal. Here are a few comments from Peter: Long radials are a hassle with vertical antennas. Can short tuned counterpoises work? Find out as I try a dual band 17/20 metre antenna at the beach. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Which is better: Vertical or Dipole?

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=pRTo01Qttbc&ab_channel=DavidCasler This is post 2380 in a continuing series of simple ham radio antennas. In this video, David Casler (KE0OG) tackles a decades-old question:  What antenna is better--Vertical or Dipole? Dave uses Antenna modeling soft wear (EZNEC+) to provide basic answers.  Of course, your results will vary, depending on height above ground, the purpose of the antenna (DX or local contacts), and geographical features, such as soil, trees, location, and weather. You could build both antennas and test the suggestions for yourself.  In my experience, an Inverted Vee antenna combines the advantages of both antennas.  But, as the old saying goes, "your mileage may vary."   Why not experiment and see what works for you?

Portable 40 meter Vertical Antenna Build

Thanks to Steve Palmer for this simple 40 meter vertical antenna project.  Although the antenna is designed for the 40 meter band, it can perform as well on the 15 meter band, using the third harmonic of the 40 meter band. This is an all-around basic antenna that will provide hours of fun and education on the ham bands.  Just take your time and be sure to install a ground radial system.   You can get multi-band performance by using 450 ohm ladder line and an antenna "tuner". ---- Thanks for joining us today.
