In this video from Carl Oliver , we learn what a loading coil is, and how it is used to reduce the physical length of a resonant antenna .  A loading coil adds inductance to an antenna and can be adjusted to allow an antenna to cover several frequencies.  This basic tutorial is hands- on, simple, and to-the-point.

This time Julian shows us his updated Amateur Radio Go Kit using a Yaesu FT-817 ND, the Chameleon Antenna MPAS (Modular Portable Antenna System), and the popular LDG-Z817 automatic antenna "tuner." This video covers part of his " Arctic Circle Training Ops 2015."  The antenna can be configured in a variety of ways, including vertical, horizontal, NVIS , and Inverted L.  Julian supplies a complete list of materials and helpful hints that you can use to make your own field deployable emergency radio station (i.e. "Go Kit").

Here's a simple effective S-Match balanced homebrew tuner for your shack.  The video is well-produced and provides several detailed views of the S- Match box and its internal components.  This tuner is based on a design created by PA0FRI. Check out his website for several more tuner designs. Several comments to this post refer to the tuning ease of this device, which covers 160 meters through 10 meters.  If you use balanced feed line , such as 450 ohm ladder line , 300 ohm television twin lead, or homemade 600 ohm balanced line , then this is the tuner for you. This S-Match balanced tuner is designed to handle 100 watts.

This truly inspirational video is for all of us who are reluctant to go portable and have difficulty with CW .  In this video, "Radio Prepper " show us a simple portable "go kit" and an even simpler HF vertical antenna that will get you on the air quickly from a remote or emergency operations site.  The 19-foot/5.79 meter antenna wire is supported by a 18.29-foot/6 meter telescoping fiberglass pole. The end-fed wire is connected to an EARCHI 9:1 Unun, which is then connected by a short length of coaxial cable to  an EM-2ATU ( antenna tuning unit ).  This assembly is then connected to an Elecraft KX2 transceiver.  A counterpoise wire runs from the EM-2ATU along the top of the ground. Using this arrangement, "Radio Prepper" was able to get several contacts, including one from Sweden . This simple HF Amateur Rad

160M antenna for small lots or gardens (http://www.dxzone.com/dx32549/160m-antenna-for-small-lots-or-gardens.html). Author:  OZ1CX. Accessed on 11 March 2017, 20:35 hrs, UTC. Please click link or insert title URL into your browser search box to read the full article. Comment: As the solar cycle declines to minimum, it's time to explore the lower HF bands (160, 80, and 40 meters) to see what they offer during this period of poor propagation.  These bands don't suffer the severe loss of signals now being found on all bands above 40 meters.  Forty meters is usable both day and night, with 80 and 160 meters doing fairly well after sunset and just before sunrise.  Perhaps it's time for you to get on 160 meters and see what's happening. The one great drawback for 160 meters is the size of the antenna, where a full-size horizontal dipole can reach more than 260 feet/79.26 meters for 1.800 MHz. Even an inverted L antenna can be large.  Vertical 1/4 monopoles can be u

Comment: Here's another great multi-band dipole antenna for those living in deed-restricted homes or apartments. In this well-written and easy to follow tutorial, James Steven (M0JCQ) shows how some wire and connectors from eBay can make a "stealth" antenna that delivers good local and DX contacts. James provides a complete materials list and an easy step-by-step guide to building this simple, inexpensive dipole antenna that fits in an attic or loft.  In James's case, he was able to design a multi-band dipole antenna fed by a single coaxial feed line that covers the 40, 20, 17, and 15 meter Amateur Radio bands. The antenna closely resembles the popu
