If you want multiband HF coverage from 160 meters through 10 meters and you can have only one antenna, why not try the "classic" doublet antenna? In this video, Steve Ellington (N4LQ) show us his doublet antenna which covers 160 meters to 10 meters, using 60-ft/18.29 m of 450 ohm ladder line and a MFJ-998 automatic "tuner."  Steve says his length of balanced feed line, coupled with the "tuner" allows, him to cover a wide range of amateur/ham radio frequencies. If you want to follow Steve's design, please cut the doublet for the lowest frequency of use.  In this case, you will be able to cover 160 meters to 10 meters with each dipole segment measuring approximately 135-ft/40.76 m.  You may have to adjust antenna length to accommodate local conditions.

One of the toughest parts of a vertical antenna installation is the preparation, building, and installing of a ground radial or counterpoise system.  The ground radial system supplies the "missing half" of a vertical antenna and is needed to improve signal strength and boost efficiency. In this video, we see one way of putting that "missing half" in the ground without too much effort. As suggested by "dixielandfarm", more short radials are preferred to fewer, longer radials.  Although there is no ideal number of radials for a vertical antenna (some AM broadcast stations use up to 120 quarter wave radials). try building a radial field using 16 to 20 buried radial wires.  Another possibility is using four to six elevated radials for your vertical antenna.  I've used this solution for frequencies between 20 and

I consider this video from Martin Lorton one of the best tutorials covering crimp connectors, wire stripping, and the proper use of heat shrink tubing.  For those of us who don't do much kit building or repair of equipment, this video is a welcome gift for those times when we must fix something at our ham stations. Martin show us some simple, effective ways to work with connectors, wire projects, and heat shrink tubing.  You may want to download this video for your personal ham radio library.  You never know when this material will come in handy.  An extremely well-done video.

I've been following the progress of Paul's (OM0ET) homemade Magloop Antenna over the course of several videos documenting the design, construction, and testing of this compact antenna. In this segment, Paul makes what he calls a "practical improvement" of his homemade magloop with the addition of a new coupler unit which doesn't require the use of screwdriver--an ingenious design feature which works very well.  Paul has given us a remarkably well-made and clean design which should encourage experimentation within the amateur/ham radio community.

Other than the mildly distracting audio track, this video from 4Z5JO does an excellent job of showing how to build a simple, inexpensive, and effective 4:1 balun for your HF antenna system.  The video provides a step-by-step method of designing and building this useful antenna accessory.  4Z5JO provides a full list of materials needed for this easy project.
