Overview: FMV-88-108 FM Broadcast High-Gain Stacked Dipole Array
The FMV-88-108 is an elite, high-performance Stacked Dipole Array specifically engineered for community and commercial FM broadcast stations requiring maximum omni-directional coverage. By vertically stacking four precision-tuned dipoles and feeding them in-phase, this system delivers a substantial 6 dBd (8.15 dBi) gain, effectively concentrating the radiated energy toward the horizon. Constructed from 6063T6 architectural anodized aluminum, the FMV-88-108 is a heavy-duty solution for FM base stations that demand high power handling, low noise, and zero-failure reliability.
Hardened Construction & Weatherproofing
Strategic engineering for persistent transmission in severe environments. The entire array is fabricated from 6063T6 ultra-corrosion-resistant aluminum alloy, ensuring structural integrity and a high strength-to-weight ratio. To ensure 100% waterproofing, the termination points of the phasing harness cables are sealed with high-grade heat-shrink tubing. The system includes a 4-way power splitter and four low-loss phasing cables, all designed to withstand extreme atmospheric conditions. The central mast, reaching an overall length of 12 meters, is shipped in modular 3-meter sections to streamline logistics and simplify field handling.
Operational Efficiency & Pattern Superiority
Omni-directional saturation with specialized "Null Filling." The FMV-88-108 is designed for Vertical Polarization, providing a true 360-degree horizontal radiation pattern. A critical feature of this array is its null-filling coverage, which ensures that the signal remains consistent and strong even in the "shadow" areas directly beneath the tower. The narrow 18-degree vertical beamwidth ensures that the majority of the 1000-Watt power capacity is directed precisely where it is needed—along the horizon—to maximize the station's broadcast footprint.
Detailed Technical Features
- High-Gain Broadcast Performance: Delivers a powerful 6 dBd gain, significantly increasing the Effective Radiated Power (ERP) of the station.
- Massive Power Capacity: Engineered to handle up to 1000 Watts of continuous RF power, facilitating long-range signal dissemination.
- Phase-Matched Signal Delivery: All four dipoles are fed in-phase through a precision 4-way splitter for perfectly synchronized radiation.
- Tactical Vertical Polarization: Optimized for reception by vehicle antennas and portable FM receivers.
- Low Noise Architecture: Specialized construction techniques ensure low-noise performance, maintaining crystal-clear audio fidelity.
- Elite Termination: Equipped with a 7/16 DIN-Female input to accommodate high-power, low-loss transmission lines.
- Modular Logistics: Despite its 12-meter operational height, the 3-meter shipping length allows for easier transport to remote or constrained sites.
- Versatile Side-Mounting: Supplied with heavy-duty stainless steel hardware specifically designed for side-mounting on broadcast towers.
Detailed Environmental Features (MIL-STD-810G Hardened)
The FMV-88-108 is precision-built to survive the most punishing mission parameters:

- Finish Options: Available in Silver Gray or Military Green powder coating for environmental protection or low-observability requirements.
Key Advantages, Benefits & Applications
Key Advantages:
- Extended Range: The 6 dBd gain effectively doubles the signal reach compared to a single dipole, expanding the listener base.
- Universal Reliability: 6063T6 aluminum and stainless steel hardware ensure the array remains rust-free for decades in coastal or humid climates.
- Seamless Installation: The modular mast and included power distribution kit allow for a "turn-key" installation at the tower site.
Key Applications:
- Community FM Broadcasting: Primary antenna system for regional and local FM radio stations.
- Information Dissemination: Ideal for PSYOPS or civil defense broadcasting where area-wide saturation is critical.
- Base Station Infrastructure: High-reliability primary radiator for high-power FM transmitter sites.
- Tactical Communication: Providing wide-area vertical coverage for VHF-band voice and data networks.
