The Shure UA505-RSMA Remote Antenna Mounting Bracket Kit is designed to facilitate the optimal placement of antennas for wireless systems, allowing them to be mounted away from the receiver or equipment rack. This kit is crucial for enhancing the performance and reliability of wireless audio setups by addressing common RF challenges associated with antenna placement.
Function Description
The primary function of the UA505-RSMA kit is to provide a flexible and robust solution for remote antenna mounting. By enabling antennas to be positioned at a distance from the main equipment, the kit helps to:
- Improve Signal Quality: Moving antennas away from potential sources of interference, such as other electronic devices or metal objects, can significantly reduce signal degradation and improve the clarity and strength of the RF signal.
- Optimize Coverage: Remote mounting allows users to strategically place antennas in locations that offer the best line of sight to transmitters, thereby maximizing the coverage area and minimizing dropouts. This is particularly important in complex environments like stages, auditoriums, or large event spaces where direct line of sight can be obstructed.
- Enhance System Reliability: By ensuring better signal reception, the kit contributes to the overall reliability of the wireless system, making it more resilient to environmental factors and user movement.
The kit supports two primary mounting configurations:
- Wall Mount: This allows antennas to be securely attached to walls, providing a fixed and elevated position that can be ideal for permanent installations or situations where a stable, unobtrusive placement is desired.
- Microphone Stand Mount: This offers a more portable and adjustable solution, enabling antennas to be mounted on standard microphone stands. This is particularly useful for temporary setups, touring, or situations where antenna positions need to be frequently adjusted or moved.
Important Technical Specifications
While the manual provides limited explicit technical specifications for the kit components themselves, it does offer crucial dimensions and part numbers:
- Wall Bracket Dimensions: 84.52 mm (Height) x 63.5 mm (Width) x 77.02 mm (Depth). These dimensions indicate a compact yet sturdy design, suitable for various installation environments.
- Included Components and Part Numbers:
- Reverse SMA Bulkhead Adapters, lockwasher, nut: Part Number 95A32436. These adapters are essential for connecting the antenna cables to the mounting bracket and ensuring a secure, stable connection. The "Reverse SMA" designation is critical for compatibility with specific antenna types and cables.
- Remote Antenna Mounting Bracket Kit: Part Number UA505-RSMA. This is the core bracket assembly that provides the physical structure for mounting.
- 6" Reverse SMA Cable: Part Number 95F31216. This short cable is likely used for connecting the bulkhead adapter to the antenna itself or to another component within the bracket assembly. The "Reverse SMA" connector type is consistent with the adapters.
Note: The kit explicitly states that antennas and bracket mounting hardware (screws, washers, and nuts for wall mounting) are not included. This means users will need to source appropriate antennas and wall-mounting hardware separately, tailored to their specific application and wall type.
Usage Features
The UA505-RSMA kit emphasizes ease of use and flexibility in deployment:
- Versatile Mounting Options: The ability to choose between wall mount and microphone stand mount provides significant flexibility for different scenarios, from permanent installations to temporary event setups.
- Clear Installation Guidance: Although the manual doesn't detail the step-by-step installation of the bracket itself, the diagrams clearly illustrate how the components fit together for both mounting types. The inclusion of bulkhead adapters and a short cable suggests a straightforward assembly process.
- Compatibility: The use of Reverse SMA connectors ensures compatibility with a wide range of Shure antennas and cables that utilize this standard.
Remote Antenna Placement Guidelines (Crucial Usage Feature):
The manual provides comprehensive guidelines for optimal remote antenna placement, which are integral to the effective use of the UA505-RSMA kit:
- Reduce Distance: Minimize the distance between the transmitter and the antenna to maintain signal strength and reduce potential interference.
- Antenna Separation: Mount antennas farther from each other to improve performance, especially when using multiple antennas for diversity reception.
- Line of Sight: Position antennas to ensure an unobstructed line of sight to the transmitter. This includes avoiding obstructions from the audience, stage elements, or other physical barriers.
- Avoid Metal Objects: Keep antennas away from metal objects, as metal can reflect or absorb RF signals, leading to signal degradation.
- Low-Loss Cables: Emphasizes the critical importance of using only low-loss reverse SMA cables for longer runs to prevent significant RF signal loss. Users are advised to consult cable specifications and calculate signal loss for their desired cable length.
- Continuous Cable Length: Recommend using one continuous length of cable from the antenna to the receiver to enhance signal reliability and minimize connection points that could introduce loss or impedance mismatches.
- Walk-Around Test: Always perform a thorough walk-around test to verify coverage before using the wireless system in a live setting. This allows users to identify and address any dead spots or areas of poor reception, and to experiment with antenna placement to find the optimal configuration.
- Avoid Wi-Fi and 2.4 GHz Devices: Advise against mounting antennas near Wi-Fi access points or other devices operating in the 2.4 GHz band, as these can cause significant interference to wireless audio systems.
Maintenance Features
The manual does not explicitly detail maintenance features for the UA505-RSMA kit itself, as it is a passive mounting solution. However, implied maintenance considerations based on the nature of the product and its usage guidelines include:
- Regular Inspection: Periodically inspect the mounting bracket and cable connections for any signs of wear, damage, or loosening, especially in portable or frequently adjusted setups.
- Cable Management: Ensure that all cables are properly routed and secured to prevent strain, kinking, or accidental disconnection, which can lead to signal loss or damage.
- Environmental Protection: While not explicitly stated, it's good practice to ensure that the mounted antennas and connections are protected from harsh environmental conditions (e.g., extreme weather, excessive dust) if used outdoors or in challenging indoor environments, to prolong their lifespan and maintain performance.
- Connector Care: Keep the Reverse SMA connectors clean and free from debris to ensure optimal electrical contact and prevent signal degradation.
In summary, the Shure UA505-RSMA Remote Antenna Mounting Bracket Kit is a practical and essential accessory for professional wireless audio systems. It provides the necessary hardware and crucial guidance to achieve superior RF performance by enabling strategic antenna placement, thereby contributing to a more reliable and robust wireless experience.
