Simple Ham Radio Antennas--Water's Edge HF Pedestrian Mobile: Wadetenna with 7 MHz loading coil


If you're having trouble viewing this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=cfh7LcLDqH4. This is post #1012 in a continuing series of "Simple Ham Radio Antennas."

Here's another great and somewhat curious antenna idea from Peter Parker (VK3YE).  Peter has adapted his "wadeantenna" to operate as a "Water's Edge HF Pedestrian Mobile...with a 7 MHz loading coil."  The antenna support is a fiberglass whip carried on a backpack.  An easily made 7 MHz coil mounted midway up the mast is used to cover the 40 meter amateur radio band.  Peter says the antenna without the coil can be used between 10 MHz and 50 MHz. In the water adapted antenna, there is no trailing counterpoise wire common to most pedestrian mobile antennas.  Instead, Peter attaches the counterpoise wire to his ankle with a strap, using the tidal wash to establish a rudimentary ground system for the antenna.  It's a good thing Peter is using his QRP rig (Yaesu-817) for this experiment.  An interesting antenna experiment that really works!
