Here's an interesting antenna "coupler" ("tuner") idea from Australian radio amateur Peter Parker (VK3YE).   According to Peter, this basic L-"tuner" doesn't require a variable capacitor. Here are some of Peter's comments: Variable capacitors can sometimes be hard to find. Especially during this time of lockdown with all hamfests cancelled. Described is a 1.8 to 18 MHz L-match antenna coupler that uses double sided fibreglass printed circuit board as a substitute. PS: Like these videos? Wish to support this channel?

Callum McCormick (M0MCS--the "DX Commander") has designed several successful HF antennas for radio amateurs. These antennas are price competitive with other brands, fairly easy to assemble and test, and produce excellent results. In this video, Callum takes us behind the scenes and shows us the design and testing procedures for his current "Nebula eXtreme Multiband HF Antenna." A thoroughly enjoyable look at antenna creation from start to finish. Here are some of Callum's comments: As I move to the "final push", I discuss the considerations including harmonics and practical problems involved with multiple elements and their tuning. We discuss element lengths, mechanical connections and hardware. Callum. #MNHR #YTB #HAMRAD

Another superb review and demonstration from Julian (OH8STN). This time, Julian examines the Chameleon Mpas 2.0 | Portable Ham Radio Antenna in actual field conditions.  If you're looking for an exceptionally crafted portable antenna, then you may want to add the Chameleon Mpas 2.0 to your Christmas shopping list. Here are some general comments from Julian: Hello Operators Recently Chameleon Antenna released an updste to the popular portable ham radio antenna, the Chameleon MPAS ( Hybrid Micro, MIL Whip, MIL EXT, CHA Spike ), seen regulary on the channel. This new system is call the Chameleon MPAS 2.0. The man portable broadband ham radio antenna is a rapid deployment specialist. Rugged construction, all weather deployment, and designed to take horr

Small Garden Vertical HF Antenna Installation

According to Peter, a little creativity and careful construction can help you get a decent HF signal from a very limited space, including a "small garden." Here's a general comment from Peter that may get those creative juices flowing: Sometimes the only solution for HF operation in small gardens is to go vertical.

If you want a basic two-element curtain array, try this "Lazy H" antenna from Hiram Vazquez. The "classic Lazy H Antenna" consists of two horizontally-polarized dipole elements which, under excellent conditions, can deliver up to 3.42 dBd over a standard dipole antenna.

Here's another great, innovative antenna project from Dave Tadlock (KG0ZZ). In this video, Dave takes us step-by-step through the design, construction, testing, and use of a simple 10 Meter Ground Plane Antenna.  Even though propagation on 10 meters is poor most days, the band will support good local contacts--perfect for informal nets and ragchews. Here some of Dave's observations: A 10 meter ground plane antenna that can be mounted on a mast or used as a ground mounted vertical antenna.

Thanks to W4AOX for this simple and helpful tutorial on how to design, build, and use a multi-band HF antenna. Although the antenna is designed for the 40 meter and 20 meter bands, it will work on the 15 meter, 12 meter, 10 meter,a nd 6 meter Amateur Radio band with an external ATU. W4AOX provides some general guidance and a materials list here: In this video I go through the steps to build a very simple, inexpensive multi band dipole antenna for the 40 and 20 meter amateur radio bands which can be used either at your home or in the field for off-grid emergency communications. Additionally, this DIY wire dipole antenna will also work on the 15, 12, 10 and 6 meter bands if your radio has an ATU or you have an external tuner. This exact DIY Dipole Antenna has allo
