Introduction
1.1
General information about this guide
This guide is valid for the 5G FR2 antennas (3591/01 and 3591/02) and
their associated accessories. In the following, the 5G low-noise block down-
converter are referred to as the LNB antenna.
These instructions offer a quick introduction on how to install the product.
For more information, please refer to the SRM-3006 operating manual
(3006/98.21).
Also read the Narda General safety instructions (3300/98.10) carefully
for information about how to operate the LNB antenna in a safe way
together with the unit it is connected to.
Keep this guide, the Narda General safety instructions (3300/98.10) and
the guide of the basic unit the LNB antenna is connected to, so that they
are always available to all users.
Only ever pass the LNB antenna and basic unit (SRM-3006) on to third
parties together with the guides mentioned above.

Product description
Two LNB antenna models are available: a directional antenna with high
sensitivity and an omnidirectional antenna. Both antennas include a down-
converter that converts the millimeter wave band from 24.25 GHz to
29.5 GHz into the SRM-3006's receive band. This means that the RF cable
between antenna and basic unit only transmits frequencies up to a
maximum of 6 GHz, which greatly reduces the cable loss compared to a
20 GHz cable. In addition, due to the fact that the downconverter is inte-
grated in the antenna, it can be used with all SRM-3006 devices without any
hardware modifications. Only a firmware update is required, which easily
can be done by the user.
The LNB antennas have a built-in battery, which is independent from the
basic unit. Thus, the runtime of the SRM-3006 is not affected by the opera-
tion of the antennas. The battery can be charged via an USB-C socket.
Connected to a USB power bank, long-term measurements can also be
performed.
Narda recommends to generally connect the antennas to the SRM-3006
using an RF cable.
