WB-Stinger-900 MHz Vertical (10 dBi) by Wireless Beehive 900 MHz Vertically Polarized Stinger (10 dBi) Stinger 900 Vertical Slip on 10 dBi No need for extra mounts for panels or yagis Smaller and more aesthetically acceptable visual impact Boost signal levels for marginal customers Speed up your installs Narrows the pattern to 55 degrees Lower Jitter Design No extra cables necessary Type N Bulkhead Connector The Fine Print: We have found the RSSI/dBm readings in the various models of Motorola Canopy equipment to be somewhat inaccurate and non-linear. If you slip a Stinger™ onto an SM you may or may not see the same dBm reading as another SM with a Stinger™ or similar antenna. What you will see and can verify is a range increase. We have had 900Mhz Stingers™ work out to a distance of 10-15 miles. However, a realistic expectation is solid performance at 5-10 miles.
