Plain-language answer: A delta loop is a triangular closed-loop antenna, often near one wavelength in perimeter on its design band.
Why it matters in the antenna
Feedpoint location and triangle orientation can change polarization, impedance, and lobe direction while height and ground reshape elevation response.
What to verify
Record apex direction, base height, side lengths, feed corner, and feed system before comparing results.
The common mistake
Assuming every triangular loop has the same polarization and pattern.
Operating boundary
Use the exact documented component, geometry, frequency, power, duty cycle, clearances, and feed/return system. Begin tests at low power and stop for heating, arcing, damaged insulation, or unstable supports.
