Simple Ham Radio Antennas--Backward Inverted L Antenna. Post #608.


If you have difficulty viewing this video, please insert this into your browser search box: https://youtu.be/SOpdXHnzIA. An interesting variant on the familiar Inverted L antennas used for the lower amateur radio HF bands (160 meters, 80 meters, and 40 meters). Stan Gibilisco (W1GV) does a good job of explaining the general theory behind random wires and how to use them for effective HF antennas.  This "backward inverted L antenna" would be useful for amateurs who have their operating station on the second floor or higher in their homes or apartments. I haven't been active on 160 meters because of space limitations, but, with this design, that situation will change.  A few months ago, Dean (KH6B) gave me a pre-assembled 160 meter inverted L antenna to conduct experiments at my new QTH in the Puna District of Hawaii Island.  Unlike my present rental home, this property has one-acre of space to erect a nice antenna "farm."  Thanks to several tall trees and my trusty archery set, I have enough incentive to erect this fairly compact antenna for the "gentlemen's band."  Stan's backward inverted L antenna should be a perfect match, since my amateur station is located in a loft above the main floor of the house.  If this design isn't satisfactory, I can always erect a conventional inverted L antenna and relocate my station to the garage storage room at ground level.  Stan's backward inverted L may help you get on 160 meters with a decent signal.  It's worth a try.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  You can follow our blog community with a free email subscription or by tapping into the blog RSS feed.  Happy Thanksgiving to all!  Aloha es 73 de Russ (KH6JRM).
