This is post 2395 in a continuing series of simple ham radio antennas.

End Fed Half Wave Antennas are simple, compact, and highly portable.  The secret to an effective EFHW antenna is the 49:1 transformer which matches the impedance of your transceiver to the extremely high impedance of the antenna itself.

In this video, "Tech Minds" shows us how to build a basic 49:1 UnUn which will protect your transceiver as well as deliver maximum efficiency for the antenna.

Here are some general comments from "Tech Minds":

Here we take a look at an End Fed Half Wave antenna which is resonant on many HF bands due to a 49:1 matching unit being used. Antenna Design Plans: http://www.infotechcomms.net/download...

Building a ZS6BKW antenna from scratch. Post #1559.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=BfUbL_4VCww. The G5RV and its popular variant, the ZS6BKW, are popular multiband HF antennas for radio amateurs. In this video, members of the Stamford Amateur Radio Association W1EE,  show us how to build a ZS6BKW antenna capable of covering the 80 to 6 meter amateur radio bands.  Here are the guidelines offered by this construction team: "The ZS6BKW is the successor to the G5RV. It's a multi-band 80-6 meter wire dipole. ZS6BKW started with the G5RV and then conducted extensive computer modeling to increase the gain, flatten the SWR a bit, and smooth out the lobes. It's also about 10 feet shorter than an equivalent G5RV. The antenna must be fed with 39 feet of 450 ohm ladder line and also must have at least 70 feet of coax feeding the ladder line. The coax and ladder line together form a matching network that brings the SWR below 2:1 (

G5RV Multi Band HF Dipole Antenna. Post #1555.

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.

Antenna for Condo Backyard-Stealth. Post #1542.

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.
