A Simple Short Vertical HF Antenna. Post 1915.

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.

A Simple Short Vertical HF Antenna.. Post #1114.

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
