Simple Ham Radio Antennas

A professionally produced video tutorial on short dipoles , prepared for a junior electromagnetics course in electrical engineering at Bucknell University . The video is being used as supplementary course material for future electrical and broadcast engineering students.  The video covers the basics of short or Hertzian dipole antennas with an emphasis on antenna theory , classification of antennas (current and aperture), general properties of short dipole antennas, and design considerations.  Although the mathematics used in this video are a bit complex, the explanation and diagrams are easy to understand.  Understanding the complexities of dipole antennas may involve a learning curve, but, when you do understand the theory behind this simple antenna, you will get a better grasp of why antennas behave as they do.  This video

Now that I've seen this excellent video by Robert Sumpton, most of my fears are gone.  In this tutorial, Bob show us how to install a PL259 coax connector without soldering the shield braid, a proven method used by hams for over 35 years, by an Extra Class radio amateur, who has been a ham for 58 years. In this video, Bob uses copper braid RG-8 coaxial cable.  A nicely done, easily understandable presentation.  For the latest Amateur Radio news and events, please check out the blog sidebars.

HF Antennas 101 (http://www.sgcworld.com/Publications/Downloads/antennas.pdf. Accessed on 23 February 2016, 03:07 hrs, UTC. Author:  Van Field (W2OQI). Special thanks to Dean (KH6B) for running off a copy of this outstanding article. Please click title link or URL address to read the full article. I'm always searching for interesting antenna articles to add to my reference library.  Sometimes, the greatest antenna articles can be found in the " QST " archives.  Such is the case here. "HF Antennas 101" by Van Field (W2OQI) appeared in the September 2004 issue of "QST" published by the ARRL. Van's concise, accurate article lists "10 tips and truisms that every ham should know." Here's the list for easy reference: An antenna doesn't have to be resonant to work.  According to Van, a non-resonant dipole fed with television twin lead, 450-ohm ladder line, or homemade open-wire and an antenna transmatch (i.e. "tuner&

King (KM4IE). Most of the antenna materials can be found at a hardware store or building supply outlet.  Initial SWR data indicate that tuning this antenna shouldn't be major issue:  20 meters (14.300 mHz--1.11:1); 12 meters (24.95 mHz--1.23:1); 11 meters (28.4 mHz--1.01:1); and 10 meters (28.4 mHz--1.0:1). Results are pending for 15 meters and 17 meters.  If you use this antenna, be sure to attach a counterpoise wire or a ground radial system. You can get detailed plans for this portable HF Antenna by visiting this website: http://www.arrl.org/files/Technology/tis/info/pdf/00043033.pdf.  For the latest Amateur Radio news and events, please check out th
