Here are some comments from 2E0VOV: I thought..... "heck" I got the stuff needed to build the antenna, so i might as well make one!..The wire is stranded 0.75mm csa keeping the antenna light for SOTA. Hope you enjoy my projects and I must learn how to edit better video's soon.. For more projects check http://www.qrz.com/db/2E0VOV 73's Sparkie 2e0vov ----- Thanks for joining us today.

Stealth HF Antennas

Image
Thanks to OH3SPN (Finland) for this easily-understood introduction to stealth antennas. This video describes stealth antennas that are dipoles, fan dipoles, and loops. If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=1aTIoz3buaQ This is post 2804 in a continuing series of simple ham radio antennas. Here are some comment from OH3SPN: I initially supported a dipole on an outdoor structure as a temporary receive antenna due to QRM from a neighbour on the main antenna. However, this provided an opportunity to talk about ideas for stealth antennas. Note: This only covers dipoles, fan dipoles and loops; vertical stealth antennas may be covered in a future video. Additionally, when talking about loops my maths may be incorrect; a loop should be a *full* wavelength on the lowest band of operation. Dipoles are obviously a half wavelength, so whilst the frame discussed will fit a 20m dipole, it wouldn't necessar

Multi-band small space DX antenna for HF

Image
If you need a simple, no radials required HF antenna for your small urban lot, then this idea borrowed from Rick (DJ0IP) may interest you. Tim (G5TM) does a good job of explaining the theory and construction procedure behind this antenna.

Easy way of installing radials for a vertical antenna

Image
Most HF vertical antennas need a ground radial/counterpoise system to function efficiently. Installing these radials can be a tedious procedure, especially if you're constructing a radial field of 32 to 64 wires. In this video from Callum McCormick (M0MCX), we see how the process can be simplified with a few simple tools.

Thanks to Australian radio amateur Peter Parker (VK3YE) for these simple, inexpensive HF antennas for those living in deed-restricted apartments, homes, or townhouses. Be sure to operate your new antenna with low power to minimize RFI (radio frequency interference) exposure to you and your neighbors.

How to build and tune a half-square antenna

Image
Thanks to Charlie of the "Red Summit RF" youtube channel for this practical guide to building and tuning a simple half-square antenna. In this video, Charlie takes us step-by-step through the design, building, and testing procedures for this 20 meter 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=j7WhC243P5E This is post 2800 in a continuing series of simple ham radio antennas. Here are some additional comments from Charlie: I take you through my steps to build this 20 meter DX antenna, including construction of the insulators, and a trip into the field to tune it up. "In the field" turned out to be a RUSS event (Radio Under the Sun Shade) which is basically a Radio in the Park in my area that is held once a month.
