This is post #923 in a continuing series on Simple Ham Radio Antennas. Interesting antenna test video from "VideosByDFP."  This field test involved the following antennas: Alpha Loop, Sr; Alpha vertical; Alpha Modo; and the Alpha EZ Military.  Rigs used in the test included the Icom IC-720D with the LDG-IT-100 Autotuner and the Yaesu FT-857D with the LDG YT-100 Autotuner.  The antenna tests were conducted between 15 October and 18 October 2015 in the upper Mojave Desert, about 120 miles/189 km north of Los Angeles, California.  Intriguing video that may give you some ideas about your next portable/emergency antenna.

Antenna Basics (http://213.114.137.49/antennas/anten.htm). (http://www.dxzone.com/cgi-bin/jump2.cgi?ID=5408). Accessed on 15 October 2016, 21:40 hrs, UTC. Author:  Harry Lythall (SM0VPO). Please insert either of these two title URL links into your browser search box to read the full article. Comment: A concise, well-written antenna tutorial from Harry Lythall (SM0VPO). Harry does an excellent job of explaining the theory and design of basic dipole and vertical HF antennas. The article explores the following questions: What is wavelength? How long should antennas be? How does an antenna work? How does a 1/4 wavelength antenna work? How do I connect a 1/4 wavelength antenna to a transmitter? How do I know if an antenna is useless? A very good introduction to antennas for the newly-licensed radio amateur.
