3. Package Contents
- 1 x Matchmaster 10MM-MA30PDF Masthead Amplifier
- 1 x 14V DC Power Supply Unit
- UV Stable Heavy-Duty Cable Ties (for mounting)
4. Setup and Installation
Before beginning installation, ensure all power is disconnected from your antenna system. This amplifier is designed for masthead installation, close to the antenna, to maximize signal quality.
Figure 1: Matchmaster 10MM-MA30PDF Masthead Amplifier. The image displays the amplifier unit with its protective cover open, revealing the input/output ports, gain adjustment dials, and the 4G/5G LTE indicators. To the left, the included 14V DC power supply unit and a coiled cable are visible. The amplifier features three coaxial ports labeled 'Output', 'VHF In', and 'UHF/V+U In', along with two blue gain adjustment dials for VHF and UHF, and a small switch for input configuration.
4.1 Mounting the Amplifier
- Select a suitable location on the antenna mast, ensuring it is as close as possible to the antenna for optimal signal reception.
- Use the provided UV stable heavy-duty cable ties to securely fasten the amplifier to the mast. Ensure the unit is oriented to prevent water ingress.
4.2 Connecting Antennas and Power
The amplifier supports two input configurations, selectable via the small switch located between the 'VHF In' and 'UHF/V+U In' ports:
- Switch Position 1 (No Signal / V+U): For use with a single combination antenna that outputs both VHF and UHF signals on one cable. Connect this cable to the 'UHF/V+U In' port. The 'VHF In' port should be left unconnected.
- Switch Position 2 (VHF / UHF): For use with separate VHF and UHF antennas. Connect your dedicated VHF antenna cable to the 'VHF In' port and your dedicated UHF antenna cable to the 'UHF/V+U In' port.
- Connect the appropriate antenna cable(s) to the 'VHF In' and/or 'UHF/V+U In' ports on the amplifier, based on your antenna setup and the switch position.
- Connect a coaxial cable from the 'Output' port of the amplifier to the input of the included 14V DC power supply unit (often referred to as a power inserter).
- Connect the output of the power supply unit to your television or distribution system.
- Plug the 14V DC power supply unit into a standard electrical outlet. The 'PWR' indicator on the amplifier should illuminate, indicating power is being supplied.
4.3 Gain Adjustment
The amplifier features independent gain adjustment dials for VHF and UHF signals, allowing you to fine-tune the signal strength for optimal reception. The dials provide up to 20dB of adjustment.
- Rotate the 'VHF' dial to adjust the gain for VHF channels.
- Rotate the 'UHF' dial to adjust the gain for UHF channels.
Adjust the gain settings while monitoring your television's signal strength meter (if available) or picture quality. Aim for a strong, stable signal without over-amplification, which can lead to distortion.
5. Operation
Once installed and powered, the Matchmaster 10MM-MA30PDF amplifier operates continuously to boost incoming television signals. The integrated 4G/5G filter automatically mitigates interference from cellular signals, ensuring a cleaner television signal.
No further user interaction is typically required after initial setup and gain adjustment, unless changes to your antenna setup or local signal conditions necessitate re-adjustment.
6. Maintenance
The Matchmaster 10MM-MA30PDF amplifier is designed for long-term, maintenance-free operation. Its robust, UV-stable, and water-resistant housing protects internal components from environmental elements.
- Periodically inspect the coaxial cable connections to ensure they remain tight and free from corrosion.
- Check the amplifier's mounting to the mast to ensure it remains secure, especially after strong winds.
- Keep the amplifier's housing clean from excessive dirt or debris, though this is rarely necessary due to its design.
Do not attempt to open the amplifier unit, as this may void the warranty and expose internal components to damage.
