DDAA1000/SRM and DD1000/SRM Placement Locations

Placement of your DDAA1000/DD1000 is likely to have a significant impact on its performance. In general, the rule of thumb with the DDAA1000/DD1000 is that the higher the placement of the antenna, the better the communication. In practice you should also place the radio itself away from computers, telephones, answering machines, and other similar equipment. To improve the data link, Data-Linc Group offers directional and omni directional antennas with cable lengths ranging from 10 to 200 feet.

When using an external antenna, placement of that antenna is critical to a solid data link. Other antennas in close proximity are a potential source of interference. It is also possible that slight adjustments in antenna placement (as little as 2 feet) will solve noise problems. In extreme cases, such as when the radio modem is located close to pager or cellular telephone transmission towers, Data-Linc Group offers a band pass filter to reduce the out of band noise.
