Thanks to Steve (KM4SLW) and his friends at "Ham Radio Portable" for this efficient, lightweight, inexpensive vertical antenna for the 20 meter and 40 meter Amateur Radio bands.   Although the antenna is designed for portable or field use, it can be used at your home station as well. Here are some details from Steve: he idea for this antenna came from the qrpguys.com website. This one is built to handle 100W on ssb. The box has one T157-2 powered iron toroid with 24 turns of 18ga. enameled wire. For 20m the core is bypassed as the antenna wire is already a 1/4 wave on 20m- 16'-5". For 40m , the connection uses the core that provides the inductance to make the wire electrically appear to be a 1/4 wave on 40 meters. The core has around

In this video from Callum McCormick (M0MCX), we see one way to design, install, and test a ground radial system for HF vertical antennas. Here are some of Callum's comments: Ground Radials are a thing of "Mystique". I use the formula of using 4-wavelengths of wire in total, cut into random lengths to suit.All my radials are LESS than 1/8th of a wavelength. For 80m, my radials are around 2.4% of the wavelength. My experience and demonstration in a real-world solution will assist our thinking. HEY, Subscribe here: https://goo.gl/thM5Vq My Shop: https://www.m0mcx.co.uk/store/pr

An inverted L antenna makes an excellent 160 meter antenna for radio amateurs short on space.  In this video, Steve Ellington modifies a design by K2AV and erects a 160 meter antenna in his back yard. The key to an efficient 160 meter vertical antenna is an extensive ground radial system.  In this case, Steve uses an interlocking counterpoise to provide the ground return for his antenna.  The antenna works despite space constraints.

Many of the antennas described in this discussion are based on ultra-light designs by N9SAD. If you're forced to use highly compromised antennas for your ham station, you may want to consider some of the ideas suggested by Eric. Here are few comments from Eric: By HAMS for HAMS Here are some super stealth ultra-lite HF dipoles made by N9SAD and some on-air testing. Here is the link to the ebay store..

In this video, Kevin show us his mobile "antenna farm" which enables communication from 160 meters to 70 cm. His antennas include a slim jim, doublet, an end-fed half-wave for 160m, and a Chameleon whip with a 9:1 balun. Here are some of Kevin's comments" In answer to many recent questions about what I use for antennas while roving around. Links to the various antenna build videos below.

An excellent introduction to antenna design basics and how to use six fundamental parameters to maximize antenna performance. Here are some general comments from the video producer: Six key antenna parameters are discussed to assist with antenna selection, antenna integration and antenna design. Antenna implementation is critical to the performance of any wireless product. Design your mechanicals around the antenna to provide ample room for the antenna and ground plane so that the antenna can radiate properly. Be sure to impedance match off-the-shelf antennas and tune custom antennas in-situ, as they will likely be de-tuned once integrated into the device due to ground plane effects, batteries, plastic enclosures and even human tissue for wearables.

Thanks to Carl (2E0EZT) for this excellent, oft times humorous look at making a basic, inexpensive 20 meter vertical antenna.  The antenna is good for both home and field use. Here are some of Carl's observations: A quick video following a conversation with a fellow operator about working lightweight SOTA or similar. I own an MP1 SuperAntenna but felt that making a simple wire antenna and a small flag pole could get you onto the lower bands (20m) quite easily and lightweight. I made this antenna during a break while working at home, it tested fine on the analyser and worked very well during a quick deployment at some high ground near home. PLEASE NOTE: the fold over wire (about 90cm) should be kept away from the rest of the wire antenna runni

Thanks to Jarrad (VK3BL) for this simple antenna switch box project. Here are some of Jarrad's comments" We discuss why Mr. T (connector) is best left as a TV Star, and why they're not suitable for use as an antenna splitter in a Ham Shack. We cover the Mini-Circuits ZSC-2-2+ HF Splitter, and why its such a good solution to the problem of splitting an antenna between receivers, especially if you want to do accurate comparisons. We also cover how to use the 'RX Loop' on the IC-7610, and demonstrate using it to split the received signal between itself and the Icom IC-R8600.

In this well-paced, tightly organized video, Tim Carter (W3ATB) shows us how to build and install a basic 80 meter NVIS (near vertical incidence skywave) antenna.  Most of the materials for this project can be found locally or in your "junk box," NVIS antennas can provide reliable, strong signals out to about 300 miles/486 km.  These antennas are perfect for local, state, and regional communications.

End Fed Half Wave Antennas are simple, compact, and highly portable.  The secret to an effective EFHW antenna is the 49:1 transformer which matches the impedance of your transceiver to the extremely high impedance of the antenna itself. In this video, "Tech Minds" shows us how to build a basic 49:1 UnUn which will protect your transceiver as well as deliver maximum efficiency for the antenna. Here are some general comments from "Tech Minds": Here we take a look at an End Fed Half Wave antenna which is resonant on many HF bands due to a 49:1 matching unit being used.

Every radio amateur should have a "go-kit" for portable or emergency operations. In this video from Michael Martens (KB9VBR), we see how simple a portable field kit can be--Michael's kit has only three well-packed bags. Here are some of Michael's comments: What do I carry with me when I hit the road for a Parks on the Air of some other kind of portable radio activity.
