The key to effective performance in a long wire or random length end fed wire antenna is the proper matching of the high impedance of the antenna to the low impedance of your HF rig.  In this video from "Signal Search", we learn how the Palomar Engineers Multi-Ratio Cube Unun makes the impedance match possible.  This unun, joined with with an external antenna "tuner" and a decent ground radial or counterpoise system, allows you to use a single wire as a multiband HF antenna. "Signal Search" shows us how the unun helps maximize antenna performance, while reducing RFI and SWR issues.

A nicely done video from Coach Helder (W2NTC) on how to set up and use the 2m/70cm rollup slim jim/J-Pole antenna by Nelson Antennas.  Coach discusses indoor and outdoor applications of this sturdy, well-crafted antenna.  Antenna tests were made using a Yaesu VX-8DR HT.  You may want to buy two of these antennas--one for your emergency "go-kit" and the other for home use.  If you feel more adventuresome, you could make your own slim jim/J-Pole from locally available materials.

A basic, no frills explanation of the theory, construction, and use of cubical quad antennas from Dave Tadlock (KG0ZZ).  Although cubical quads can be built for the HF Amateur Radio bands, most radio amateurs seem to prefer such antennas for the VHF/UHF bands where the dimensions, materials, build time are less than similar antennas for HF.  Dave does an excellent job of introducing this versatile antenna and shows you how to build one for your home shack.  If you need an antenna for serious VHF/UHF DX or to just reach a fringe repeater site in your area, then the cubical quad may be the best antenna for you.

There are still many unused CB (Citizens Band) antennas collecting dust at garage sales, auctions, estate sale, and your neighborhood recycling center.  You can put these antennas to good use on the 10 Meter Amateur Radio band by making a few easy adjustments with a wire cutter and an antenna SWR analyzer. Tony (KD8RTT) and his brother, Andy (KK4LWR) do just that in this well-made video tutorial.  In this case, Tony and Andy trim and test a coil shortened mobile CB whip for the 10 Meter band. The vertical element is trimmed and checked frequently with a MFJ-259B SWR Analyzer.  If you feel ambitious, try a similar procedure with one of those 102 in/259.08 cm steel whip antennas used on big trucks.  Years ago, I converted one of these large whip antennas to the 10 Meter band and mounted it on a telescoping fiberglass mast with four elevated radi

A nicely done End Fed Halfwave vertical antenna from 2E0VOV.  The heart of the project is the impedance transformer, which must be carefully made to insure a safe match between the high impedance of the EFHW and your rig.  EFHWs make good HF antennas if you have limited space for a ground radial or counterpoise system.

One of the best general purpose, multiband HF antennas is the classic doublet fed by balanced feeders going into a balanced antenna "tuner."  In this video, Adrian ("One Time Pad") documents the design, construction, and adjustment phases of his homebrewed doublet antenna.  Here's the complete list of materials and tools needed to build this versatile HF antenna: "Antenna Components: Copper wire for radiating element (I used multi –strand Flexweave) Ladder line/Open wire/Ribbon (I used 300Ω ribbon because its neater) x3 eye bolts with associated nuts as washers x1 straight wastewater pipe connector x2 access plugs for above wastewater pipe connector x2 wing nuts and bolts x2 Dog bone Isolators (to isolate end of each antenna leg) x1 spool Rosin core solder (i.e. solder with embedded flux) Cable ties Heat shrink tu

Top Five Get-On-The-Air-Quickly Ham Radio Antennas, Post #1547. http://www.donkeith.com/n4kc/article.php?p=22. Author:  Don Keith (N4KC). Please click link to read the complete article. Comment: Antennas can be a confusing issue for newly license radio amateurs or for those returning to Ham Radio after a prolonged absence. In this well-written, easy grasped article, Don suggests five basic antennas that can get you on the air quickly with a minimum of time and money.  Don's says these antennas are nearly foolproof and can be made with local resources: "They are easy to build for most anyone who is willing to try and do not require any special tools or test equipment. They may be crafted from easily available materials and cost very little, so there is not much downside if you mess them up. They are not necessarily the be-all, end-all of RF radiators but they do work well enough to give a good experience to the user. They are not necessarily the best fo
