FAQ
What frequency ranges does the Bosch B40-MB50 antenna support?
The antenna operates across three primary frequency ranges: 698-960 MHz for lower-band cellular and LTE services, 1710-1990 MHz for mid-band GSM and 3G networks, and 2100-2700 MHz for higher-band 4G and LTE-Advanced cellular technologies. This broad coverage ensures compatibility with most cellular carriers and network standards in North America and other regions.
What is the antenna gain and how does it affect performance?
The B40-MB50 delivers 5.5 dBi of isotropic gain, which represents the antenna's ability to concentrate RF energy in the horizontal plane compared to an ideal isotropic radiator. This gain level provides measurable signal improvement for cellular communications while maintaining the simplicity of an omni-directional pattern that doesn't require precise pointing toward cell towers.
Which Bosch devices is this antenna compatible with?
This antenna is specifically designed for Bosch Conettix plug-in cellular communicators, including the B440 Conettix Plug-in Cellular Communicator, B441 Plug-in cellular module (VZW CDMA), B442 Conettix Plug-in GPRS Cellular Communicator, and B443 Conettix Plug-in HSPA+ Cellular Communicator. It provides the RF interface for these devices to connect to cellular networks for alarm reporting and remote monitoring.
Can this antenna be used for both indoor and outdoor installations?
Yes, the B40-MB50 is rated for outdoor, indoor, and cellular network applications. The weather-resistant construction allows direct exposure to environmental elements when mounted externally, while the compact size and discreet design make it suitable for indoor placement in equipment rooms or enclosures where cellular signal penetration is needed.
What are the physical dimensions of the antenna?
The antenna measures 3.30 inches (83.80 mm) in height and 1.44 inches (36.50 mm) in depth. This compact form factor allows installation in space-constrained locations while providing adequate radiating surface area for effective performance across the supported frequency bands. The small footprint minimizes visual impact in aesthetic-sensitive applications.
How does the omni-directional pattern simplify installation?
The 360-degree horizontal radiation pattern means the antenna receives and transmits signals equally in all directions around its vertical axis. This eliminates the need for precise alignment toward cell towers, reducing installation complexity and time. Technicians can mount the antenna in the most convenient location without worrying about directional optimization, making it ideal for sites without clear line-of-sight to cellular infrastructure.
