MB9000 Antennas Configuration

Here is one thing we run into. The MB9000 when placed on a tabletop requires that it's antenna to be placed horizontal with the tabletop surface if you have a PCMCIA adapter otherwise it interferes with the PCMCIA adapter. This is not the recommended orientation. Other problem is that the antennas on the PCMCIA data cards are in close proximity about 7cm. Recall that to avoid radio frequency intereference antennas should be approximately separated by at least half a wavelength. At 800mhz wavelength = 37.5cm half wavelength is 18.75cm. For Sprint at 1900mhz wavelegth = 12.5cm, half wavelength = 6.25cm.
