Here's an excellent example of what can be done with a very short HF vertical in a portable or field operation. In this video, "RadioPrepper" uses a 6 m/19.68 ft telescoping fiberglass fishing pole to support 19 ft/5.79 m of antenna wire.  The key to the success this antenna is the EARCHI 9:1 UNUN.  On this day, an Elecraft KX2 was able to reach Sweden for a QSO.  Notice how a complete ham station was carried in a small plastic case, making this arrangement perfect for an impromptu field operation.

Thanks to Gil (aka RadioPrepper.com) for this simple, effective vertical antenna which can be used for both home and portable operations.  The 19 foot/5.79 meters antenna wire is supported by a 19.68 foot/6 meter telescoping fiberglass fishing pole.  The antenna system uses a small Z-Match antenna "tuner" and a 9:1 EARCHI UNUN along with a suitable ground radial system.  Gil's rig is an Elecraft KX2 running about 5 watts output.  In the video, he's enjoying a cw contact with a station in Sweden.  Gil's entire system (rig, antenna, tools, and power supply) is contained in a small carrying case which can be stuffed in a knapsack or kept in a vehicle for emergencies.  A very nice arrangement.

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...
