Gridstream RF
Coupling Antenna
Installation Guide
Overview
This publication outlines the procedure for installing the Gridstream RF Coupling Antenna on
Gridstream RF Electric Endpoints.
Figure 1. Gridstream RF Coupling Antenna
This antenna couples radio frequency energy to an external antenna. This is useful for meter
installations where there is difficulty in obtaining adequate reception. For example, meters located in
metal enclosures or in a basement. The coupling antenna utilizes a coaxial cable routed to the remote
antenna. 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 RF Coupling Antenna installations. The part number and description
is as follows:
40-1705 flex loop, 2.5 ft. antenna cable, cable tie, adhesive
In the cas
e where the length above is insufficient, Land
is+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.
