This site contains support documents for my Column on Antennas and Transmission Lines in The Canadian Amateur magazine, a publication of Radio Amateurs Canada and support for projects at the Ottawa Amateur Radio Club. It also contains a list of presentations that I have made to the Ottawa Amateur Radio Club, the Quarter Century Wireless Association and the West Carleton Amateur Radio Club in Ottawa.NEW: I have added a section that compares the performance of several commonly used portable antennas. It includes measurements and simulation results (4nec2) as well as all of the 4nec2 files that you can use to modify these antennas for your own needs. A short tutorial on my 4nec2 work flow is also presented for novice users of the simulator. See the drop down list under Antennas.
