Antenna practice
PA0RDT Mini Whip
A practical antenna note for PA0RDT Mini Whip, connecting geometry, feed point, installation environment, measurement, and tuning.
Antenna practice
The antenna includes its environment
To understand PA0RDT Mini Whip, consider geometry, height, ground, nearby objects, feed line, and the exact measurement plane.
- 01
Geometry
Length, spacing, diameter, and symmetry change resonance and pattern.
- 02
Feed point
Impedance, balance, common mode, and coax loss can dominate the result.
- 03
Measurement
Record height, environment, and calibration plane; an SWR curve alone does not describe the whole antenna.
