INTRODUCTION
The PDWA3900 Yagi antennas are made to work with pointto-point and point to multi-point applications.
These high gain antennas are ideal to use with Precision
Digital's PDW series because they give you the flexibility of
installing the antenna exactly where you need to bridge your
point-to-point or point to multi-point wireless process signals
while keeping the PDW unit in a convenient location for
monitoring.
Each Yagi antenna is factory tuned on a network analyzer
for best power match and lowest VSWR, offering the best
possible performance.
The PDWA3900 also comes complete with a mounting kit
that includes stainless steel hardware.
Extension cable accessories are available to extend the
distance between the Yagi antenna and the PDW30 or
PDW90 wireless units. See Ordering Information for details.
