Radio Amateur Training Planning and Activities Committee (RATPAC) comprises Amateur Radio Operators of a wide variety of backgrounds and experiences. Together, we host nationwide Amateur Radio Zoom presentations twice a week, Wednesdays on general radio topics and Thursdays on amateur radio emergency communications. Our Website- www.ratpac.us List of upcoming & previous sessions- tiny.cc/ratpac-... The topics are selected from audience recommendations and the planning committee then seeks topic experts or discussion panel members. The presentation audience consists of thousands of amateur radio operators worldwide who participate directly in the Zoom sessions or with video links of the presentation and related documentation sent out after each session.

There is more 160 info in this presentation than I have found in 6-8 months of research. Thank you for taking the time to do this!

Glad it was helpful!

I had a 160 m horizontal loop supported by four 200ft towers that was next to the beach. It worked well for local and some DX. I fed it with 450 ohm feed line and could tune it up to 30 MHz.

If you have that 100’ clear around your antenna, let’s see … maybe dig a pond and fill it with *REALLY SALTY* water …😀
If you don't want anything growing in that _"No Man's Land",_ maybe make the soil a little more conductive with *copper sulfate.* Of, if you *DO* want things to grow, there's probably some fertilizer that is highly conductive.

You might want to try removing your top hat and instead add four twenty-ish foot guy wires from the very top. Once down twenty feet with copper wire add and egg shaped insulator to extend the "guy wires" to the ground with something that's non conducting like nylon rope. Then put about fifteen feet of copper wire between each egg insulator and solder it to the twenty-foot wires you have coming down from the top. So instead of the horizontal top hat you have it would look more like a pyramid sitting on top of the antenna.

Can you please give some more details about the dimensions? What pipes were used for the “mast” and what was used for the capacity head, length diameter? How many space is needed between the windings, so the helical is no coil.
Just thinking doing that type of Antenna for 40m. You can get the plastic tubes in 3m lengths. Making the windings at the top close to another will create a coil. So 3m hight is sufficient.

Can you make the files for the 1" winding spacers available?

What about a lined pond full of salt water
