Building High Power, High Q, Loading Coils - This page describes the loading coil (inductor) that W8WWV built for my center-loaded 160 meter (1.83 MHz) vertical antenna.

ZR6KMD 2M Beam Antenna - This design was adapted from an article in the ARRL Handbook and built with simplicity and duplicity in mind. This antenna is a vast improvement over a standard dipole with a forward gain of around 8db with a front to back ratio of 10db.

2 meter 1/4 wave Ground Plane - 146 Mhz quarter wave antenna plan

Slim Jim 2m Vertical - This VHF 145 MHz antenna is easy to build and with no radials. It shows equal gain of 5/8 lambda. It is light weight, you can hang it somewhere (on a tree may be) and work.

Dual Band J Pole - Dual band J pole operational over the entire 6Mtr band (50 – 54MHz) and the entire 2Mtr band (144 – 148MHz), slightly favouring the upper half of both bands by VK6YSF

VP2M DXpedition to Montserrat - Seven operators from six US States will travel to the small island of Montserrat in late January of 2007 to activate that island in a most unique way. Instead of big antennas, and tons of equipment, this DXpedition will instead focus on lightweight gear and portable operations.

C6 Bahamas - Sand Dollar Villa is equipped with two antennas and two power supplies, and an extensive tool kit. Has proven to be an excellent spot for people on vacation who also like to engage in casual DX ham radio operation.

TLDetails - Transmission Line Details. This utility program shows the impedance and SWR at both ends of a transmission line and the details of power loss in the line. It includes characteristics for over 40 built-in line types. You can modify these values to see how small changes affect the results or to specify custom lines. All program inputs may be changed directly or you can use spin buttons to make the changes. If you are using a moderately fast computer you can hold down a spinner and "watch the movie" on the charts as the results are recomputed. By AC6LA
