Simple Ham Radio Antennas

If you lack the space to erect a full-sized dipole or G5RV antenna, then this modified DX Commander All Band Vertical Antenna from Callum (M0MCX) may be what you need. In this video, Hayden (VK7HH) shows how he assembled, tested, and used this antenna design at his home station.

So I got myself a DX Commander All Band Vertical from Callum - the DX Commander and WOW! This antenna is so simple and allows me to operate on EVERY HF band using only a small footprint in my yard. Verticals can traditionally be known as noisy antennas too, so I show HF noise levels at my new QTH. DX Commander Build video https://www.youtube.com/watch?v=iiDB5...

An excellent presentation from "AmRad Podcasts" on the theory, construction, testing, and use of 1/4 wavelength antennas. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=haizSAYquUg Here are some comments from the podcast: Today I’m going to show you how to make a 1/4 wavelength antenna for the 70cm amateur radio band. Of course physics doesn’t care who’s using her laws, so this design can be applied to really any frequency, though the lower in frequency you go, the bigger it gets! We’ll cover a little basic antenna theory, build it, install it in the attic and do some testing & tuning on a nanoVNA vector network analyzer. **NOTE: If you are going to make one of these, the distance from the center of the SO239 to the edge of the metal plate MUST be considered as part of the radial system. So you MUST subtract this length from the wire radials when cutting them. Sheet metal brake/shear used: Harb

How to build a simple 6 meter dipole antenna with the aid of a 3D printer. Thanks to Kevin Loughin (KB9RLW) for this homebrew 6 meter antenna project. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=2hdKCQX1lv8 Here are some comments from Kevin (KB9RLW): Leonids meteor shower was starting up, so I needed an antenna for 6 meters. Let's make a dipole. Thingiverse link to the dipole center insulator: https://www.thingiverse.com/thing:280... If you like my videos, please subscribe here: http://www.youtube.com/user/loughkb?s...

Here's another informative and fascinating antenna idea from Australian radio amateur Peter Parker (VK3YE). In this video, Peter shows us how to design, build, and test an oblong loop antenna for 28 and 50 MHz bands. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=zf2tIUEIBRE Here are some comments from Peter (VK3YE): I've had success with 50 ohm oblong loops for 144 MHz but what about lower frequency bands? In this video I try ones for 28 and 50 MHz.

Thanks to Callum (M0MCX) and "QSO Today" for these simple, inexpensive, and effective antennas for radio amateurs.  These antennas can be made from locally available resources. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=Pg7WbTEkFds Here are some comments from Callum (M0MCX): I show you exactly how to build the THREE best wire antennas that all ham radio operators should be able to build in their sleep. Presented originally at QSO Today. Callum. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Thanks to Tim (G5TM) and Rick (DJ0IP) for this "Super Multi-Band Antenna" covering all Amateur Radio Bands between 80 meters and 10 meters. If you have the space and some tall supports, this "Lazy Loop Antenna" will prove itself to be an excellent DX antenna. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=6ycBtbIKOqI Here are some general comments about the antenna: Thanks again to Rick, DJ0IP for publishing details of this antenna which he says provides great gain at higher angles for 80 and 40 metres as well as very good gain 20 metres through 10 metres. Let’s use MMANA-gal modelling to see if this agrees. Check out Rick’s website here: https://www.dj0ip.de/my-favorite-ante... Connect with my channel by subscribing and commenting.
