TranSystem Inc., a world wide
leader in MMDS/MDS
technology, offers a complete line of PCS, WCS and radar filtering downconverters.
Our designs have been copeid by many, but the original out performs the
rest. The digital ready AIDC easily integrates with parabolic antennas
or any of our esthetically correct antennas.
|
|
TranSystem Inc., has been
designing and manufacturing MMDS down converter since 1992.With a solid
design and outstanding workmanship, we are able to sell into the most demanding
markets such as the USA and Brazil with at least a hundred thousand units
per year. Product performance, good product value, and in-time customer
service are the important elements for such success. As we have claimed
our product features as below, we invite you to test and see the performance
yourself. |
