Making a 49-1 UnUn for End-Fed Half Wave Antennas


Thanks to John of the "Amateur Radio On The Air" youtube channel for this helpful accessory for end-fed half wave antennas.  This project will help your HF transceiver cope with the high impedance found in end-fed antennas.

This is post 2839 in a continuing series of simple ham radio antennas.

Here are some comments and corrections from John:

Just been re-watching this video and noticed a mistake the correct value for the capacitor should be 100pF not 100uF.

"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.
