TX2400-BLG Series 2.4GHz 12dBi N-Male FRP Antenna

Updated: April 2026

Ultra-High 12 dBi Gain via 1200 mm Multi-Dipole Array

The 1200 mm extended structure integrates multiple collinear dipole elements tuned to 2.4 GHz. This collinear array compresses the vertical beamwidth and concentrates radiated energy toward the horizon, achieving a measured 12.0 dBi gain — approximately 6 dB more than a standard 6 dBi antenna, translating to roughly 4× the effective radiated power in the horizontal plane. This makes the TX2400-BLG-120 the optimal choice for long-distance LOS links in open fields, campuses, and industrial yards.

Industrial N-J Interface & All-Weather FRP Radome

The N-J (N Male) connector is rated for high-power RF transmission with minimal insertion loss, making it the standard interface for outdoor base stations and professional AP equipment. The FRP radome is UV-stabilized, waterproof, and structurally rigid — maintaining antenna alignment and RF performance in sustained winds and heavy rain without additional weatherproofing enclosures.

Validated on a vector network analyzer across the 2400–2500 MHz band: VSWR ≤ 1.5 maintained at all measured frequency points, confirming <4% reflected power and maximum energy transfer efficiency. Return loss exceeds 14 dB across the full operating band.

Q: Can the TX2400-BLG-120's N-J (N Male) connector connect directly to SMA-equipped devices?

A: No direct connection is possible. The N-J interface is a 50 Ω RF connector rated for high-power outdoor base station equipment, while SMA is a smaller-format connector common on indoor modules and gateways. To bridge the two, use a low-loss "N Female to SMA Male" RF pigtail cable. Ensure the cable is rated for 2.4 GHz with minimal insertion loss (<0.3 dB/m) to preserve the antenna's 12 dBi gain advantage.

Q: How does the 1200 mm length translate into a measurable 12 dBi gain improvement over shorter 2.4 GHz antennas?

A: At 2.4 GHz, a single half-wave dipole measures approximately 62 mm. The 1200 mm tube accommodates a collinear array of multiple dipole elements phased to add constructively in the horizontal plane. Each doubling of array elements adds ~3 dB of gain. The TX2400-BLG-120's 12 dBi represents roughly 6 dB more than a standard 6 dBi antenna — approximately 4× the effective radiated power toward the horizon, directly extending usable range in open LOS environments.

Q: Does the FRP radome require additional weatherproofing at the N-J connector base for long-term outdoor installation?

A: The FRP radome body is inherently UV-resistant, waterproof, and structurally stable across a wide temperature range. However, the metal N-J connector junction at the antenna base is the most moisture-vulnerable point in any outdoor RF installation. For deployments exceeding 6 months or in high-humidity coastal environments, wrapping the connector junction with self-amalgamating (self-fusing) RF waterproof tape is strongly recommended to prevent moisture ingress, which can cause VSWR degradation and long-term corrosion of the connector's center pin.
