Building Project: 9:1 UnUn & Long Wire Antenna

 


The secret to making a great long wire antenna is the building of a 9:1 UnUn to insure a proper match between the high impedance of the wire antenna and the low impedance of your HF transceiver.

In this video, TinkerJohn (W5CYF), takes us through the design, building, and testing phase of this 9:1 Unun project.  The build is fairly simple, and you should be able to assemble the unit in just a few hours.

Here are a few comments from TinkerJohn (W5CYF):

Simple and inexpensive to build the 9:1 end fed long wire antenna is a good antenna for both portable and home use. This antenna, like all antennas, has it advantages and disadvantage. You’ll see some of both in this how to video. Amazon Link for other suggested items that may be related to this video: https://www.amazon.com/shop/w5cyftink...

"Big Hat" Vertical Antenna. Post #1422.

If you can't see this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=xgOqP8uPEPc. 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!

Antenna for Condo Backyard-Stealth. Post #1542.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=MXTYTytR56A. 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.

G5RV Multi Band HF Dipole Antenna. Post #1555.

Image
If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aeNHIQ_j4Dk This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  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.
