Overview
This publication outlines the procedure for remote passive antenna installation on Gridstream RF
Electric Endpoints.
Figure 1. Remote Passive Antenna
This antenna couples radio frequency energy from a Landis+Gyr Gridstream RF Electric Endpoint's
902-928 MHz antenna into a coax cable connected to a remote antenna located at an optimal location
for better connection to the Gridstream RF network. Coupling loss (including the 2.5 ft. cable)
ranges from 5 to 9 dB, with 5 being a typical value. Environmental performance is rated for: 0 to
95% relative humidity, -40 to +85° C.
Coupler Part Numbers
The same coupler is used for all remote antenna installations. The part number and description is as
follows:
• 40
-1705 flex loop, 2.5 ft. antenna cable, cable tie, adhesive
In the case where the length above is insufficient,
Landis+Gyr recommends the extension cable
listed below, terminated with a female “N” connector on one end and a male “N” connector on the
other:
• 19
-1742, extension cable, 20 ft.
