[Tinyos-help] How to disable antenna on telosb mote

2008-12-02 Thread JD
Greetings, I need to place a Directional Antenna on the Telosb mote and disable the built-in omni-directional antenna. Would anybody please let me know if how I can do that. I did some digging into the mail archives, but could not hit on anything. Thanks in the anticipation. Thanks, JD

You can do this by changing C73 on the TelosB from pins 1 and 2 to pins 1 and 3 (just moving it over, essentially). This connects the SMA socket to the RF pins on the CC2420 (and disconnects the PCB antenna). http://webs.cs.berkeley.edu/tos/hardware/telos/telos-revb-2004-09-27.pdf -jay On Tue,
