Transmission Line Experiments Evidence and theory that indicates we do not comprehend radiation. We don't know what light is.

Open Source Hardware Pages Links to HW Projects which may be obtained completely assembled directly from the manufacturer.

Some Thoughts on HOA Antennas contains some slides from a short presentation to the San Juan County Amateur Radio Society club, 9 February 2024.

Another Look At Transmission Lines is a draft of an article I wrote several years ago that was recently published by the Radio Society of Great Britain in RadComm+

The common theory for coaxial line which has its basis in a circuit model by Heaviside from the 1880's is at odds with the physics expressed by Einstein and Schelkunoff. Previous articles have shown theoretical results and practical applications from a newer understanding. This article further discusses some of what we've missed, why we've missed it, and why it might matter.

Here are the Text of the Article and Accompanying Figures .

An October 2016 Pacificon Presentation, SWTL Summary and Demonstration which is a sort of summary of the SWTL technology, demonstrations and other activities on these pages. Please note that this is NOT "G-Line" as described by Goubau (which required slowing the wave down) nor is it the same as what Tesla described.


2nd Demo -100 meter SWTL (view on YouTube) - transmission/recovery of 144 MHz power guided along a single .013" (0.32 mm) conductor transmission line (SWTL) at 144.5 MHz using very light weight launchers. This system can be used to power quadcopters/aerostats for continuous flight while providing extremely low loss connection to elevated antennas - enabling quickly deployable, long range, very high bandwidth communications systems for Internet, emergency and other communications.




Power transmitted over a single 0.32mm wire (view on YouTube) 1st Demonstration - transmitting real power across a short single .013" (0.32 mm) conductor transmission (SWTL) at 146 MHz.


Any Ham Can Have A 400' Tower! October 2015 Pacificon Presentation, SWTL+Aerostat.
 Using SWTLs to Power Multi-Rotor Aircraft which Support a High-Altitude Antenna A way to keep a quadcopter or other motorized aerostat aloft permanently while at the same time supporting and feeding antennas at great height.

Propagation Measurement Using a Quadcopter, This article describes the use of a quadcopter to measure the relative attenuations due to beam deformation by ground and attenuation due to terrain and foliage absorption. QEX May/June 2016 (with permission ARRL)

Pacificon 2011 Antenna Forum, I gave a presentation includes an overview of three different amateur applications for surface wave transmission line, along with a new antenna theory for understanding conventional antennas such as dipoles and monopoles as surface wave devices. All but the first of these, "A Flying Antenna" have been published as a three part series in ARRL QEX.
