General Description

The Shure PA805Z2-RSMA is a passive directional antenna that improves

RF performance by rejecting off-axis RF signal. Positioned remotely, antennas

can be aimed directly at transmitters.

The antenna attaches to a microphone stand or to the separate wall-mounting

bracket, and delivers the following benefits over standard omnidirectional

half-wave antennas:

• Reduced interference

• Improved RF signal-to-noise ratio

• Antenna gain (8 dBi) helps overcome cable loss

Installation Instructions

1. Determine the length of cable required to connect each antenna to the receiver or antenna/power distribution system. Use the shortest length of cable pos-

sible, because longer cable runs increase power and signal loss.

Important: Only use low-loss reverse SMA cables to prevent signal loss.

2. Use reverse SMA cables to connect an antenna to each of the ANTENNA A and ANTENNA B ports of the receiver or antenna/power distribution system.

General Description

Antenna Benefits

Describes advantages like reduced interference and improved RF signal-to-noise ratio.

The Shure PA805Z2-RSMA is a passive directional antenna designed to enhance RF performance by rejecting off-axis RF signals. This antenna is intended for remote positioning, allowing it to be aimed directly at transmitters for optimal signal reception. It offers several advantages over standard omnidirectional half-wave antennas, including reduced interference, an improved RF signal-to-noise ratio, and an antenna gain of 8 dBi, which helps to overcome cable loss.

Function Description:

The primary function of the PA805Z2-RSMA is to provide focused RF reception, minimizing unwanted signals from other directions. By positioning the antenna remotely and aiming it at the desired transmitters, users can achieve a cleaner and more reliable wireless signal. The directional nature of the antenna helps to isolate the intended signal, making it particularly useful in environments with multiple RF sources or potential interference. It attaches to a microphone stand or a separate wall-mounting bracket, offering flexible installation options.

Important Technical Specifications:

Frequency Range: The antenna operates within a frequency range of 2050 to 2700 MHz, with a Voltage Standing Wave Ratio (VSWR) of less than 2:1, indicating efficient power transfer.
Antenna Gain: It provides an antenna gain of 8 dBi at 2.45 GHz (typical), which is crucial for compensating for signal loss over longer cable runs.
3 dB Horizontal Beam Width: The antenna has a 3 dB horizontal beam width of 100 degrees, defining the angular spread where the signal strength is at least half of its peak value.
Efficiency: At 2.45 GHz (typical), the antenna boasts an efficiency of 89%, meaning a high percentage of the input power is converted into radiated power.
Impedance: The impedance is 50 Ω, which is standard for RF systems, ensuring compatibility with most receivers and distribution systems.
Polarization: The antenna features linear polarization.
Front-to-back Ratio: It has a front-to-back ratio of 24 dB at 2.45 GHz (typical), indicating its ability to suppress signals from the rear relative to the front, further enhancing its directional properties.
Connector Type: The antenna uses a Reverse SMA connector.
Dimensions: The physical dimensions are 105 x 164 x 27.5 mm (H x W x D).
Net Weight: The antenna weighs 2.5 oz.

Usage Features:

Installation: When installing, it is recommended to determine the shortest possible cable length to connect each antenna to the receiver or antenna/power distribution system, as longer cable runs increase power and signal loss. Only low-loss reverse SMA cables should be used to prevent signal loss. The antennas connect to the ANTENNA A and ANTENNA B ports of the receiver or distribution system.
Positioning: Antennas should be positioned to ensure an unobstructed line of sight to the transmitter, including the audience. They should be pointed directly at the transmitters, with the rear side facing away from sources of interference (e.g., Wi-Fi access points). Spacing antennas farther apart can improve diversity performance. For optimal results, minimize the distance between transmitters and antennas by placing antennas near the stage rather than at a front-of-house position.
Walk-around Test: Always perform a walk-around test to verify coverage before using the wireless system in a live setting. Experiment with antenna placement to find the optimum location and mark any trouble spots.
Safety: The manual emphasizes several safety instructions, including reading and keeping instructions, heeding warnings, following all instructions, and not using the apparatus near water. It also advises cleaning only with a dry cloth, ensuring proper ventilation, and avoiding installation near heat sources or open flames. The product should not be modified, and operation should be within its specified temperature range.

Maintenance Features:

Cleaning: The antenna should be cleaned only with a dry cloth.
Servicing: All servicing should be referred to qualified service personnel. Servicing is required if the apparatus has been damaged in any way (e.g., damaged power supply cord or plug, liquid spilled, objects fallen into the apparatus, exposure to rain or moisture, or if it does not operate normally or has been dropped).
Power Cord Protection: The power cord should be protected from being walked on or pinched, especially at plugs, convenience receptacles, and the point where it exits the apparatus.
Attachments/Accessories: Only attachments and accessories specified by the manufacturer should be used.
Unplugging: The apparatus should be unplugged during lightning storms or when unused for long periods.
Environmental Considerations: The apparatus should not be exposed to dripping and splashing, and objects filled with liquids should not be placed on it. It is also noted that the equipment should not be disposed of in the normal waste stream.

The PA805Z2-RSMA is a robust and reliable solution for improving wireless microphone system performance, particularly in challenging RF environments, by providing focused and interference-resistant signal reception.
