The Zapperbox A1 Indoor/Outdoor Antenna by Televes (Model: ZXA1) is a versatile antenna designed to enhance television signal reception, particularly for ATSC 1.0 and ATSC 3.0 signals. It features a built-in amplifier and integrated LTE and 5G filters, aiming to provide clear and robust signal reception while minimizing interference.
Function Description:
The primary function of the Zapperbox A1 antenna is to receive broadcast television signals for use with a ZapperBox, set-top box, or TV. Its design allows for both indoor and outdoor installation, offering flexibility in placement. A key feature is the removable reflector, which can significantly improve signal gain and minimize interference from the rear, especially in environments with multipath reflections. This makes the antenna more directional, requiring it to be aimed towards broadcast towers for optimal performance. Without the reflector, the antenna can operate with increased omnidirectionality, which might be suitable in areas with very strong signals. The integrated LTE filter helps to reduce interference from 4G LTE signals, while the integrated 5G antenna and filter address potential interference from 5G cellular broadcasts, ensuring a cleaner TV signal.
Important Technical Specifications:
- Outputs: The antenna features multiple outputs, including a 5G Cellular Out (Input 1), an output for future use (MIMO) (Input 2), and a TV Connection (Output 3). Inputs 1 and 2 are capped and terminated to reduce noise interference.
- Frequency Range:
- 5G: 630-960 MHz and 1.7-2.7 GHz.
- UHF (Vertical): Channels 14-36 (470-608 MHz).
- High VHF / UHF (Horizontal): Channels 7-13 (174-216 MHz) and Channels 14-36 (470-608 MHz).
- Gain:
- 5G: 0 dBi.
- UHF (Vertical): 32 dBi*.
- High VHF / UHF (Horizontal): 23 dBi* / 32 dBi*.
- *Self-regulating gain.
- Crosspolar Rejection: >13 dB.
- Power: 150mA @ 5V DC.
- Dimensions: 14" x 14" x 4" (without pole mount).
- Temperature Range: -5°C to 45°C.
- IP Rating: IP53, indicating protection from dust and water spray.
Usage Features:
- Reflector Use: The reflector is generally recommended for both indoor and outdoor installations to improve reception for ATSC 1.0 and ATSC 3.0 signals by increasing forward gain and minimizing rear interference. This makes the antenna more directional, requiring careful aiming towards broadcast transmitters. In areas with very strong signals, the antenna can be used without the reflector for increased omnidirectionality.
- Installation Options: The antenna supports multiple mounting configurations:
- Table Mount (with reflector): Involves removing pole mounting hardware from the reflector, attaching the reflector to the antenna using screws, and then placing it on a flat surface.
- Wall Mount (with reflector): Similar to table mount, but the assembled antenna and reflector are attached to a wall using two screws (not included).
- Pole Mount (with reflector): The reflector is fastened to the antenna with screws, and then the entire unit is attached to a pole using a clamp and wing nuts.
- Connection Steps:
- Connect the Power Injector (G) to the ZapperBox/Set-top Box/TV.
- Use the RF Cable (I) to connect the Power Injector (G) to Output 3 on the Antenna (A).
- Use the USB Cable (F) to connect the Power Injector (G) to the Power Adapter (H).
- Plug the Power Adapter (H) into a wall receptacle.
- Included Components: The package includes the antenna (A), clamp (B), wing nuts (C), screws (D), reflector (E), USB cable (F), power injector (G), power adapter (H), RF cable (I), and a wrench (J). A PH #2 screwdriver is also needed but not included.
Maintenance Features:
- Lightning Protection (for outdoor installations): If installed outdoors, the antenna system should be grounded to protect against voltage surges and static charges. This involves proper grounding of the mast and supporting structure, the antenna lead-in wire to an antenna discharge unit, and connection to grounding electrodes, following the guidelines of the National Electrical Code (ANSI/NFPA70) or Canadian Electrical Code (CSA C22.1). The lightning arrestor or 75 ohm coaxial grounding block should be mounted close to where the coaxial cable enters the house. Ground wires should be copper or aluminum, number eight (8) or larger, and secured to the house every four to six feet.
- Environmental Protection: The IP53 rating provides protection against dust and water spray, contributing to the antenna's durability in outdoor environments.
- Warranty: Any alteration or modification to the product or usage not in accordance with product instructions voids the warranty.
- Safety Warnings: Users are advised not to expose the power supply to rain or moisture to prevent fire or shock hazards. Installation near power lines is dangerous, and installation instructions should be followed carefully.
