The FCC-4 is a tuned dipole antenna operating within the 325 MHz - 1000 MHz frequency range.
Model TDS-535 Tuned Dipole Set provides an accurate standard for precise EMI and site attenuation measurements (per OET-55 and ANSI C63.5). This half wavelength dipole set is manufactured per the FCC balun design and is individually calibrated per ANSI C63.5 at 3 and 10 meters.
The FCC-2 is a tuned dipole antenna operating within the 65 MHz - 180 MHz frequency range.
The FCC-1 is a tuned dipole antenna operating in the 25 MHz - 70 MHz frequency range.
