Dipole antenna FCC-3

radioruggedtuned

Designed per the FCC specitications, this Tuned Dipole antenna is ideal for site attenuation measurements. Features 170 MHz to 340 MHz Individually Calibrated FCC or VDE site attenuation Rugged Construction Low Loss, Low VSWR. Product Details Our FCC-3 dipole antenna provides an accurate standard for precise EMI and site attenuation measurements (per OET-55 and ANSI C63.5). The FCC-3 is manufactured per the FCC balun design and individually calibrated. This dipole antenna consists of a matching balun, two telescoping elements, balun clamp for mounting, and a tape measure to adjust the element lengths. 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 90 watts. The FCC-3 tuned dipole antenna has two quarter wavelength elements for a total of λ/2 and must be adjusted to the desired frequency. The theoretical element length is (300/FMHz /2), however we provide slightly different lengths that are tuned to the maximum Return loss. The calibration tables provide a list of the frequency points and the optimized element length.
