How to make a 20 meter Half Square Antenna with brackets

Image
If you want to make a simple, effective DX antenna, then this 20 meter Half Square design from Chuck (KK6USY) may be what you need. Chuck takes us step-by-step through the design, construction, and testing phase of this useful antenna. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=-lnxlc9Q17U Here are some comments from Chuck (KK6USY): In this videoI show how I make your own DIY 20m Half Square antenna with brackets I made on my 3D printer. Can’t put up a really high horizontal antenna for 80-meter DXing? Maybe the vertically polarized “Half-Square” might bethe antenna for you. Merch. : https://kk6usy-ham-radio-adventures.m...

The best QRP portable DX antenna

Image
If you want a low angle, QRP portable DX antenna, please consider this modified "Bobtail Curtain" design from Australian Amateur Radio operator Peter Parker (VK3YE). The antenna is easy to make for HF bands from 14 MHz to 28 MHz.  The antenna can be made from locally available materials.

Consider it if you want a low radiation angle for DX, don't have very tall masts and wish to operate on or near a conductive surface. A good write-up on the Bobtail Curtain is here: http://www.antentop.org/w4rnl.001/scv...

Simple $3.00 Ham Radio Antenna-2M Moxon

Image
You don't have to spend a lot of money to make a sturdy, efficient Moxon Antenna for the 2 meter Amateur Radio Band. In this video from Sean ("Ham Radio Dude"), we see how a few old camper stools, a length of RG-59 coaxial cable, a few nuts and bolts, pvc pipe, and several spacers can be converted into a portable 2 meter Moxon Antenna.

I have heard the stories of a Lawn chair dipole and Yagi - (Check out https://www.youtube.com/watch?v=5doak... for Ham Radio Crash Course's Lawn Chair Dipole) or https://qsysociety.org/2009/01/04/6-m... for a 6 meter lawn chair moxon (This idea is nothing new) Links referenced: Antenna Top Moxon build instructions (VERY GOOD INSTRU

5 Band EFHW Antenna 80m-10m|49:1 End Fed Half Wave

Image
If you need a simple, efficient 5 band HF antenna, then this modified End Fed Half Wave Antenna from Hayden (VK4YE) is for you. The antenna measures 25 meters long (82 feet) and uses a counterpoise and a 49:1 impedance matching network.  A wide range antenna transmatch (i.e. "tuner") should be able to help keep SWR within limits. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=sLteM18NnYc Here some observations from Hayden (VK4YE): Here are my experiments and modifications with an EFHW (end-fed half wave) based on the VK4YE design, testing, 80m loading coil, the coax counterpoise, and the common mode toroids. This allows a antenna for smaller spaces and backyards.
