This is a wonderful demonstration of the way a yagi or beam antenna works. I've never seen such a vivid explanation.
MOBILE - ICOM-706MKGII to a Hamstick antenna or 2 metter/440 whip.
ANTENNAS - My antenna system includes an A3S tri-band beam on a 40 foot tower, 80 and 40 meter dipoles mounted on the tower, a G5RV, and a 5BTV HF Vertical. On VHF and UHF I use a Diamond X-200A dual band vertical and a Radio Shack discone scanner antenna.
LOGGING PROGRAM - I am using the Ham Radio Deluxe logging program with computer control of the ICOM-7300, Elecraft K-3, and the ICOM-746. For serious contest efforts, I use the N1MM program. I publish my logs to the eQSL service and the ARRL Log Book of the World (LOTW).
