Some customers have contacted us concerning the "External antenna does not improve performance on the AirCard 875" entry in the Sierra Wireless Knowledge Base.
The issue discussed in the entry is that some antenna adapters for the Sierra Wireless AirCard 875 PC Card have a short SSMB connector.
This warning does NOT apply to the AirCard 875 compatible adapters that we sell.
Our adapters do not have a short SSMB connector. We have successfully tested our adapters with several AirCard 875 PC Cards. We used Sierra Wireless' Watcher application to confirm that the adapters made contact and signal improvement was seen.
