Model TDS-535 Tuned Dipole Set provides an accurate standard for precise EMI and site attenuation measurements (per OET-55 and ANSI C63.5). Our half wave Dipole Set is manufactured per the FCC balun design and is individually calibrated per ANSI C63.5 at 3 and 10 Meters. This Tuned Dipole Set should be considered as a standard reference for frequencies below 1000 MHz. All Sets come contained in a rugged, lightweight storage case and includes four Baluns, Element extension rods, telescoping Elements, 10 Meter Cable, Tape Measure and a Clamp for tripod mounting. Two Dipole Sets in one case (TDS-535-2) is available as an option.
