[Tinyos-help] Antenna gain on tmote

[Matt Thompson]

Hi,

Does anyone know the dBi gain of the PCB antenna on the tmote sky 
modules??  We have layed out a board with fractus 1dBi gain antennas, 
and we're not getting close to the range of the tmote antennas.  Trying 
to figure out if this is due to lack of gain, or other 
design/manufacturing issues (unmatched impedance).

Cheers,
Matt
