Pctel MFT-121 VHF Mobile Antenna Field Adjustable Frequency Range 118-940 MH

The PCTEL MFT-121 is a field-adjustable mobile antenna engineered for wideband coverage across 118–940 MHz, giving technicians and fleet operators the flexibility to tune a single antenna to multiple frequency assignments without returning to a depot or stocking separate antennas for each band. Built around a compact whip configuration and rated for up to 150 Watts, the MFT-121 is well suited for demanding mobile deployments in commercial, public-safety support, and professional communication environments. It mounts to the widely adopted 3/4" NMO standard, making integration straightforward on most professionally installed mobile radio platforms.

Key features & benefits

• Wide Frequency Coverage — Spans 118–940 MHz, enabling a single antenna to serve across multiple radio bands and reducing the need to carry band-specific spares in the field.
• Field-Adjustable Tuning — Technicians can adjust the antenna on-site to match a target frequency within the supported range, streamlining multi-frequency and frequency-migration deployments.
• Unity Gain Performance — Delivers unity gain across its tunable range, providing a consistent, predictable radiation pattern for reliable mobile communication links.
• 150-Watt Power Handling — Rated to 150 Watts maximum, accommodating higher-output mobile radios used in commercial and professional communication systems.
• Standard 3/4" NMO Mount Compatibility — Designed for the 3/4" NMO58UNC mount, one of the most common professional mobile antenna mounting standards, simplifying installation on already-equipped vehicles.
• Compact Whip Form Factor — Maximum length of 24 inches (61 cm) keeps vehicle profile low while maintaining effective radiation characteristics across the tuned frequency.
• Fine Wire Element — The 1.6 mm (0.062") antenna wire diameter contributes to a low-profile, lightweight installation with minimal aerodynamic drag on mobile platforms.
