Ham radio ground loop

WebA year later, I started phase-two. I cut a 6 foot section of wire out of the loop, half-way around the 40m loop as a daring experiment to give me a halo dipole for 80m. It worked! Band-changing from 80m to 40m was a nightmare though; out to the garden, lower the loop, connect the ends (or disconnect them!) and hoist the loop back up. Ugh! Phase ...

WebOrganizing an effective grounding system in the ham shack requires the ham radio operator to address the two major aspects of grounding. They are: First - Compliance … WebBy definition, a ground loop is a voltage differential between any two points. Ground loops often manifest themselves as an RFI problem. Almost without exception, ground loops are caused by incorrect wiring practices. Because their severity is affected by the amount of current drawn, they're typically seen (or heard) only when transmitting.

WebOn the 40-meter band a dipole elevated just 4-meters (13 feet) above ground can provide very effective NVIS propagation in a radius of several hundred miles. The precise height above ground for the very best NVIS performance is not a well-agreed value. WebA counterpoise is simply a long, insulated wire that attaches to the ground connection on your antenna tuner. The best counterpoise is 1/4-wavelength at the lowest frequency you intend to use. That’s a lot of wire at, say, 3.5 MHz, but you can loop the wire around the room and hide it from view.
