Multiband HF portable antenna, the easy way. Post #1124.

Here's an ultra simple and effective multiband HF antenna for both portable and emergency use.  This antenna could also be used in the upcoming ARRL Field Day event on 24-25 June 2017.

In this video, "rcobo107" (AC2RJ) wraps 35 feet/10.67 meters of speaker wire around a 20 foot/6.097 meters long fiberglass pole, creating a HF vertical helix antenna.  The copper shield of his coaxial feed line serves as the antenna counterpoise.  An antenna "tuner" is used to reduce the SWR on the antenna. This homebrewed antenna works on several HF bands, including 6 meters as evidenced by contacts made during the recording of this video.  You may want to make one of these simple antennas for portable use. The antenna can be stored easily in your vehicle.
