I found this fascinating article while I was searching for antenna mast ideas on the eham.net website. Although this not a "simple" antenna construction article, two people equipped with some basic tools, lumber from a home improvement store, and a few parts from a marine supply outlet should be able to design, build, and use this mast support in a few days of casual work .  Craig outlines this project in easy-to-follow-steps and illustrates the process with excellent photographs.  The completed project can be used for Field Day, vacation operating, or even at home.  The construction is sturdy and should stand up to the weather.

This arrangement would serve as a good portable or emergency antenna.  This end-fed antenna could also be used in deed-restricted areas, as long as you nested the antenna to ground level after use.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated regularly.  You can follow our blog community with a free email subscription or by tapping into the blog RSS feed.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

Every ham shack needs a " dummy load " to test and tune your transmitter before it goes on the air.  This video from "69furball69" (Steve) is an innovative, homebrew approach to building your own dummy load.  Although there isn't much audio in this video, the steps are clearly laid out and easy to follow.  In essence, a dummy load is a number of non-inductive resistors in parallel to achieve 50 ohms over a wide frequency range .  The requirements of homebrew dummy load are simple:  It must be cheap; it should insure a 50 ohm load over a wide frequency range; and it must allow for the attachment of monitoring equipment to test and tune the transmitter.  You can use a clean, empty quart-sized paint can, some mineral oil to cool the resistors, and some non-inductive resistors connected in parallel for your resistive network.  I

A nice, down-to-earth description of a simple, practical, and easily made portable or emergency antenna .  In this video, "YeOldeScience" shows us how to use two spools of "camping clothes line " wire to make a multiband dipole.  This 18-gauge wire can be bought at any store that sells camping equipment .  Amazon.com also sells a similar product.  This antenna resembles a commercial antenna called the "Yo-Yo", which can be spooled out to various lengths to suit whatever band you wish to work.  This homebrewed antenna is surprisingly tough and can be packed into a pelican case with your QRP rig, battery, and various tools for a truly portable station.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  You can follow our blog community with a free email subscripti
