Symmetricom 150-615 GPS Antenna Up Converter Suits 142-615 Downconverter Antenna [Used]
( 233470997323) )
Lightly Used • With Power Supply & BNC/TNC Pigtail Cable • Enables Long Coax Downlead Runs • Requires Downconverter Antenna • Excellent Condition
A lightly used Up Converter unit for use with a roof mounted GPS antenna. This unit requires either a Downconverting antenna (such as the 142-150 type - I believe), or a regular GPS antenna with a matching external down-converter unit. The antenna and Downconverter is not included. It will not work with Meinberg downconverting antennae.
An GPS antenna down/up converter combination may be used when signal losses in the antenna cable limit the distance between the receiver and the antenna assembly. Many applications requiring cable lengths to 1500 feet will benefit from the use of a down/up converter assembly. At just over 250 feet in cable length, the benefits can be realized using a down/up converter assembly versus the use of low loss cable and amplifiers. Signal strengths and noise immunity are the main advantages of using the antenna down/up converter assembly, as well as the cost benefits over the use of low loss cable and amplifiers.

Usually GPS receivers, when shipped with the optional antenna down/up converter, are configured to provide the appropriate DC power (+12 VDC) for the antenna down/up converter assembly. The included external power supply may also be used.
