What the thread found
- The Paralinx Array is a five-input MIMO panel antenna designed to extend range and improve signal robustness for the Tomahawk wireless system, operating in the 5.1-5.8 GHz spectrum
- Each antenna port on the Array has a maximum gain of 19 dBi
- Tested range performance extends from 2,700 feet to one mile, though actual range depends heavily on environmental conditions and specific use cases
- The Tomahawk receiver contains an internal PCB antenna for its back-channel communication, which is a fixed antenna rather than an external one
- Dynamic Frequency Selection (DFS) enables devices to automatically adjust their operating frequency within certain 5 GHz channels, providing access to more channels and the ability to shift away from noisy frequencies
- The Tomahawk receiver has an internal antenna that scans for the best available channels to operate on
Depends on
- Range performance is variable and not guaranteed, being highly dependent on environmental factors and individual deployment scenarios
- A discussion occurred regarding whether external array antennas on certain wireless systems comply with FCC regulations, with some participants questioning official approval status, though no definitive resolution or documentation was provided
- Specifications for overall system range increase when using the Array antenna were not quantified in the thread
