Formerly branded under Laird External Antennas and now manufactured under TE Connectivity, the FG4505W UHF Omni Antenna continues to set the standard for high-performance commercial base station infrastructure. Designed with full 20 MHz wideband tuning across 450 to 470 MHz, this antenna eliminates the need for tedious field cutting or narrowband frequency matching, making it plug-and-play for multi-channel MOTOTRBO™, Kenwood ProTalk®, and land mobile radio (LMR) repeater systems.

The FG4505W features a precision-machined aluminum mounting ferrule with an integrated N-Female RF connector recessed inside the base sleeve. This design protects the feedline connection against moisture intrusion and physical vibration fatigue. Whether deployed on industrial towers, commercial rooftops, or water storage tanks, its high-efficiency internal brass architecture ensures continuous, low-loss radiation across your entire operational footprint.

Key Features & Operational Benefits

• Full 20 MHz Wideband UHF Coverage: Pre-tuned at the factory for 450–470 MHz, supporting multiple transmit and receive pairs across duplexers and multi-channel repeaters without field trimming.
• True 5 dBd (7.15 dBi) Horizon Gain: Collinear radiating elements flatten the signal pattern toward the horizon to dramatically boost talkback range for field portables and mobile units.
• Heavy-Duty Fiberglass Radome: UV-treated, high-density white fiberglass enclosure protects internal elements against solar yellowing, acid rain, ice loading, and salt air corrosion.
• 125 MPH Wind Survival: Built to commercial tower specifications to maintain structural integrity and vertical radiation alignment in severe storm environments.
• Solid Brass Radiators: Internal radiating elements are directly soldered to eliminate mechanical Passive Intermodulation (PIM) and maintain low insertion loss over years of service.
• Direct DC Grounding: DC-grounded internal design provides electrostatic discharge (ESD) protection to divert atmospheric static buildup away from sensitive repeater receivers.
