Teletronics TT 2400 - Manual (Page 60)

Appendix G: Antenna Diversity
Latest firmware provides “Choose Antenna” option.
Since version 3.1.4x and 3.4.x, This new feature has been incorporated
. There are 3 options: “Diversity”, “Use
Antenna#1” and “Use Antenna #2”. If the wireless frequency in the area is very crowded there will be lots of
interference. Using the default
“Diversity” option might not be the best option to achieve optimal performance. Please
configure “Use Antenna #2” for TT2400 and “Use Antenna #1” for TT5800 to force the cards to use only those ports at
all times for both RX and TX operations. This will under most cases give you extra output power and receive sensitivity.
Make sure also that U.FL cable adapter for the MiniPCI radio card is connected properly matching the antenna number
you selected. Please use the following pictures to identify antenna port numbers:
