Half-Wave Tuned Dipole Antenna Kit
- Implements a precision half-wave tuned dipole antenna system covering 30 MHz–1000 MHz using four calibrated baluns (DB1–DB4).
- Designed per Appendix E of ANSI C63.5 reference antenna drawings for site validation and antenna calibration applications.
- Provides nominal 50 Ω impedance with VSWR <2.0 (average 1.5:1) and maximum continuous input power of 25 Watts.
- Covers four frequency subranges: 30–65 MHz (DB1), 65–180 MHz (DB2), 180–400 MHz (DB3), and 400–1000 MHz (DB4).
- Enables Normalized Site Attenuation (NSA) calibration of Open Area Test Sites (OATS) and Semi-Anechoic Chambers (SAC).
- Serves as the mandatory reference antenna for broadband antenna calibration using the ANSI C63.5 reference antenna method.
- Supports radiated emissions compliance testing per FCC, CISPR 16-1-4, and international EMC standards.
- Used as a substitution antenna for Effective Radiated Power (ERP) and Effective Isotropic Radiated Power (EIRP) measurements of intentional radiators.
- Improves radiated test accuracy by providing calculable antenna factors using the ANSI formula: 20*log(freq in MHz) – 31.9 + balun loss.
- Enhances EMC laboratory efficiency through tunable elements, collapsible extensions, and frequency-specific balun selection.
