Hollyland Spares - External Fiberglass Antenna (for SOLIDCOM M1)

The Hollyland Replacement External Fiberglass Antenna (manufacturer part number HL-ATN09) is a genuine factory-original spare part engineered specifically for the Solidcom M1 and Solidcom M1 Pro wireless intercom base station hubs.

While the M1 base station houses an integrated directional panel antenna, the system relies on a pair of external Fiber-Reinforced Plastic (FRP) antennas to transition into an omnidirectional communication profile. Because base stations are frequently mounted high on light stands, truss systems, or broadcast vans where they are vulnerable to impacts, keeping an official replacement antenna on hand is essential for maintaining full venue coverage.

1. Omnidirectional 360-Degree Broadcast Radius

The primary technical function of the HL-ATN09 fiberglass antenna is to reshape the base station’s RF footprint. When a pair of these antennas are attached, they expand the system beyond the directional front-facing limits of the built-in panel:

• True 360° Sphere of Coverage: It enables a reliable operational communication radius of up to 300 meters in all directions from the hub.

• Large-Scale Venue Mapping: This omnidirectional spread is vital for open, sprawling production environments like sports stadiums, multi-stage music festivals, and convention exhibitions where the crew is scattered across a massive footprint rather than gathered in front of the base station.

2. Heavy-Duty Fiber-Reinforced Plastic (FRP) Construction

Live event production demands rugged hardware that can survive harsh weather and mechanical stress. The HL-ATN09 is purpose-built to meet these structural challenges:

• Fiberglass Composite Core: The antenna element is shielded within a high-density, weather-resistant fiberglass tube. This architecture prevents bending, snapping, or internal solder-joint fractures caused by accidental drops or collisions with gear cages.

• Environmental Element Shielding: Unlike exposed wire antennas, the non-conductive FRP casing completely seals the internal electronic components from rain, extreme heat, dust, and humidity, ensuring reliable 1.9 GHz DECT signal propagation in any climate.

3. Optimized 1.9 GHz DECT Frequency Tuning

As a genuine Hollyland spare, this antenna is tuned precisely to match the electrical impedance and wavelength requirements of professional full-duplex intercoms:

• Maximum Signal Gain: It delivers a balanced gain output tailored to maximize the receiver's sensitivity ($\le -93\text{ dBm}$) without introducing harmonic distortion or data packet dropouts.

• Adaptive Frequency Hopping: It works in perfect harmony with the Solidcom M1's automatic frequency selection algorithms, providing clean pathways for full-duplex team conversations across up to eight active beltpacks per hub.

4. Fast Threaded Tool-Free Installation

On a fast-moving production set, a damaged antenna needs to be swapped out instantly to keep the communication matrix online:

• Hand-Tightened Interface: Features a standard, knurled metal base connector that screws directly onto the top antenna terminals of the Solidcom M1 hub. No specialized tools, wrenches, or technical calibrations are required.

• Secure Electrical Contact: The high-tolerance threading prevents the antenna from loosening due to wind vibration or localized rumble from PA subwoofers, maintaining consistent electrical and RF contact throughout a multi-day broadcast.
