CommScope DB404-B Omnidirectional Antenna | UHF | 450-470 MHz | 3.8dBd

When your communication network cannot afford dead zones, the CommScope DB404-B delivers consistent, wide-area UHF coverage. Formerly manufactured under the Andrew Solutions brand, this exposed dipole antenna is a trusted standard for base stations requiring absolute signal reliability.

Unlike standard fiberglass antennas, the DB404-B utilizes a rugged aluminum radiator and mast. This heavy-duty construction withstands wind speeds up to 100 MPH while maintaining structural integrity. The integrated Vapor-Bloc harness seals out moisture, preventing the signal degradation common in lesser antennas over time.

Safety and equipment longevity are built directly into the design. All radiators operate at DC ground, providing a low-resistance path to dissipate lightning strikes and static buildup away from your expensive radio equipment.

Installation is straightforward right out of the box. It includes the DB365-OS pipe mounting kit, allowing you to securely attach the antenna to round members between 1.25 and 3.5 inches in diameter. Upgrade your infrastructure with an antenna designed to outlast the elements.

Key Features:
• True Omnidirectional Coverage: Provides a full 360-degree horizontal beamwidth to eliminate coverage gaps around your base station.
• Advanced Moisture Protection: Features a Vapor-Bloc cable harness that seals out humidity and rain for consistent signal distribution.
• Integrated Lightning Protection: DC-grounded radiators safely route static and lightning energy away from your connected radios.
• Adjustable Radiation Pattern: The quasi-omni design allows you to space elements at 90 degrees for a circular pattern or align them for an elliptical offset.
• High Power Capacity: Safely handles up to 250 watts of input power, making it ideal for high-output repeater systems.
• Complete Mounting Hardware: Ships with the DB365-OS kit for immediate, secure installation on standard piping.

Frequently Asked Questions

Is the CommScope DB404-B the same as the Andrew DB404-B?

Yes. CommScope acquired Andrew Corporation, so the DB404-B is the exact same high-quality antenna previously sold under the Andrew Solutions or Talley brand names. The performance and specifications remain identical.

How does the lightning protection work on this antenna?

The antenna features a DC-grounded design. This means the radiating elements provide a direct, low-resistance electrical path to the mounting tower or ground system. This safely dissipates static buildup and helps protect your connected radios from lightning-induced surges.

Can I adjust the coverage pattern of this antenna?

Yes. The DB404-B features a “quasi-omni” design with two stacks of dual dipoles. By spacing the elements at 90 degrees, you achieve a standard circular omnidirectional pattern. Alternatively, you can align them collinearly to create an elliptical pattern if your coverage needs are directional.

Are there special shipping considerations for this item?

Because this is a heavy-duty industrial antenna weighing 14 lbs and measuring 60 inches in length, it is considered an oversized parcel. Please account for potential freight shipping requirements and handling times when planning your installation schedule.
