Designed per the FCC specifications, this Tuned Dipole antenna is ideal for site attenuation measurements.
A.H. Systems FCC-4 half-wave dipole antenna, also know as the reference dipole antenna, is the simplest form of an antenna. This dipole consists of a matching balun and two horizontal elements and includes a mounting clamp, and a tape measure to adjust the element lengths. Each antenna element is adjusted to a quarter wavelength (half wavelength total) this will create a precise resonating response at the frequency of interest.
The antenna balun is constructed per the W. K. Roberts design as specified in the ANSI C63.5 standard and consists of a folded balun that converts the 70-ohm (at resonance) to 50-ohm impedance. This balun design exhibits a low VSWR, low balun loss and can handle power up to 60 watts.

Shielding Effectivness Test Guide
The AEH-510 Azimuth and Elevation head is used to assist the test engineer in pointing the mounted test antenna towards the device under test. This adjustable antenna mount has a rugged 4" mounting surface with a Captive 1/4-20 male thread for mounting all of A.H. Systems and most other compliance measurement antennas.
