Simple Ham Radio Antennas

  One of the best antennas for Amateur Radio satellites is the Quadrifilar Helical Antenna (QFH). In this video, David Gilbert shows us the entire design and construction process, culminating in several successful satellite contacts. You can modify this design for other satellite uses, including weather and NASA satellites.

Here are some comments from David Gilbert: This video shows how and why I built a 435 MHz QFH antenna for ham radio satellites, including a few examples of the signals that I captured. The design parameters are derived from the online QFH antenna calculator at https://jcoppens.com/ant/qfh/calc.en.php The STL files for this model can be download free of charge from https://www.printables.com/model/1293...

Russ Roberts (KH6JRM).   The 4 Element Hentenna Beam for 2 Meters by N5NNS      Having been a ham for 27 years and knowing that the most important part of any station is the antenna, I have built, designed, and redesigned antennas for over two decades. I always look for simplicity and, more than this, effectiveness. I want a wide band-width, reasonable gain and inexpensive construction. I have built yagis, dipoles, quads, verticals, loops, and pretty much anything you can imagine. My XYL says "You should spend less time building and more talking." And she is right to a degree but the feeling I get when a project c...

  Another simple, inexpensive HF antenna is the popular "Random Wire Antenna." In this video, Walt (K4OGO) discusses all of the pros and cons of this basic HF antenna.  As long as the length is chosen carefully and a sturdy balun is used, you will have success with this antenna design. This antenna is ideal for both home station use and field operations such as POTA and SOTA.

  Here's another great HF antenna idea for those living in deed-restricted housing (HOA, CC&Rs). In this video, George Brown (M5ACN) uses his attic to erect a modified fan dipole antenna.  George says this set up has given him contacts from 102 countries in 2024. The antenna is simple, inexpensive, and very efficient. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=NEC-_M3uoGg.
