Building a great low-cost QRP Antenna-The Speaker Wire Antenna.


 How would you like to build a multiband HF antenna using locally avaiable materials?  

You can if you follow Mark's (AA3K) instructions for his modified doublet antenna.

All you need is some speaker wire, 450-ohm ladder line, and a sturdy "antenna tuner" capable of handling a balanced feedline.

Here are some comments from Mark (AA3K):

What can you do with a bit of speaker wire? You can make a speaker wire doublet, a great low-cost QRP antenna. The speaker wire doublet is an effective multiband Amateur Radio antenna for low power (QRP) field use. The speaker wire doublet along with an antenna matching unit will get you on the air and excite your portable Amateur Radio activities like POTA and SOTA. This HF multiband doublet antenna can be used on all amateur radio bands down to the lowest frequency the antenna is cut for. As this antenna is not tuned to any specific frequency, it is considered a doublet instead of a dipole.

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.

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.

Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise.  Why not equip your bicycle for 2 meter/70 cm mobile operation? In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station.  The project is straight forward, simple, and gives you emergency communications while you peddle down the road.
