X300 144-430MHz Dual Band Fiberglass Base Station RPT Repeater Antenna with Ground Plane Radials
The X300 is a dual-band VHF/UHF base station antenna designed for stable and extended-range communication in 144 MHz and 430 MHz frequency bands. Featuring a high-gain collinear structure (6.5 dBi @ 144 MHz, 9.0 dBi @ 430 MHz), it delivers enhanced signal strength and reliable omni-directional coverage for fixed station installations.
With a low VSWR (≤1.5) and 50 Ohm impedance, the X300 ensures efficient power transmission and reduced signal reflection, supporting a maximum input power of 200W. The antenna is vertically polarized and constructed with a durable fiberglass radome and copper radiating elements, providing strong weather resistance and long-term outdoor stability.
Standing at 3.1 meters in height and available with SO239 or N-Female connectors, the X300 is suitable for amateur radio base stations, repeater systems, emergency communication networks, and industrial wireless applications. OEM customization is available to meet specific project requirements.

Core Parameters
Operating Frequency:
144 MHz (VHF)
430 MHz (UHF)
The optimized radiation structure increases effective radiated power (ERP), improving communication distance and signal penetration.
Impedance: 50 Ohm
Ensures proper impedance matching with standard coaxial transmission lines, minimizing reflection loss.
VSWR: ≤ 1.5
Low standing wave ratio ensures efficient power transmission and reduces transmitter stress.
Polarization: Vertical
Designed for standard ground-based communication systems requiring vertical polarization compatibility.
Maximum Input Power: 200 Watts
Supports high-power radio systems and repeater installations.
Gain:
6.5 dBi @ 144 MHz
9.0 dBi @ 430 MHz
Structural Design
The X300 adopts a collinear vertical design structure to achieve:
-
Omni-directional horizontal radiation pattern
-
Enhanced gain on UHF band
-
Stable elevation angle for long-distance ground-wave propagation
This configuration is ideal for repeater towers, building rooftop installations, and communication masts.
