1 About the R&S TSMS-OMN70
The R&S TSMS-OMN70 is a super wideband omnidirectional antenna for mm-wave
frequency range that fits for all use-cases of the R&S TSMS53DC super wideband
ultra compact downconverter. The frequency rage of the R&S TSMS-OMN70 is wide.
The antenna can be used:
●Between 4.5 GHz and 70 GHz with medium RF parameters (out of band)
●Between 17 GHz and 53 GHz with optimal RF parameters (in band).
The antenna pattern is optimized for drive- and walk-testing with transmitters on a typi-
cal base station height over ground. When looking at the vertical pattern, the gain max-
imum is about 30 degrees to 60 degrees above the horizon, while the horizontal pat-
tern remains omnidirectional. For details, see the data sheet.
Intended use
The R&S TSMS-OMN70 antenna is designed for connection to the R&S TSMS53DC
downconverter. The antenna is optimized for drive and walking testing for 5G FR2
bands and possible future 6G bands. It can be carried in a bag or mounted on a holder.
Observe the operating conditions and performance limits listed in the data sheet.
Target audience
This document targets technicians, operators and maintenance personnel from net-
work operators, testing service providers, infrastructure vendors. The required skills

3 Connecting the R&S TSMS-OMN70
3.1 Connecting to the R&S TSMS53DC
The R&S TSMS-OMN70 antenna is designed for connection to the R&S TSMS53DC
downconverter. You can connect the antenna to one of the RF In connectors of the
R&S TSMS53DC, depending on the frequency range.
Figure 3-1 shows the connection to R&S TSMS53DC. You can connect the
R&S TSMS-OMN70 to R&S TSME6 or R&S TSMA6B in the same manner.

Prerequisites
●R&S TSME-ZQC is available.
RF in sub 6 or sub 17 GHz range: connect the R&S TSMS-OMN70 to the RF In
(RF Bypass) connector of the R&S TSMS53DC
1. Use an RF cable with an SMA plug adapter (2.4mm/1.85mm to SMA).
Note: The SMA connector is sensitive to mechanical stress. Use the following han-
dling precautions.
● Always use a torque wrench and mount the cable end with 60 Ncm to 90 Ncm.
● Do not stack adapters directly at the SMA connector. If you need to use adapt-
ers, then always use a specific adapter cable (order no. 4900.1700.00).
2. NOTICE! Excessive tightening can damage the connectors.
To connect to the "RF In ≤ 17 GHz" (RF bypass) connector of the R&S
TSMS53DC, proceed as follows:
a) Carefully align the connector of the cable along a common axis.

b) Mate the connectors along the common axis until the male pin of the inner con-
nector engages with the female socket of the outer connector.
c) Turn the nut of the outer connector until the connectors are coupled.
d) Torque the nut to the specified limit using a calibrated torque wrench.
3. Connect the cable to the RPC 1.85 mm connector of the R&S TSMS-OMN70.
RF in the 17 GHz to 53 GHz range: connect to 1.85 mm (V) connector
1. Use an RF cable with an 1.85 mm (V) plug connector.
Note: The V connector is sensitive to mechanical stress. Use the following han-
dling precautions:
● Always use a torque wrench and mount the cable end with 90 Ncm.
2. NOTICE! Risk of cable damage.
● Use only cables with V plugs for the connection to the V connector.
● Use the port saver (V-Adapter Male-Female, order no. 5009.5859.00) for the V
connector.
Connect the RF cable with V plug to the "RF In 17-53 GHz" connector of the R&S
TSMS53DC.
Follow the instructions as described in "RF in sub 6 or sub 17 GHz range: connect
the R&S TSMS-OMN70 to the RF In (RF Bypass) connector of the R&S
TSMS53DC" on page 7.
3. Connect the cable to the RPC 1.85 connector of the R&S TSMS-OMN70.
3.2 Connecting to the holder R&S FR4-5G-A3
Prerequisites
●The antenna stick with holder R&S FR4-5G-A3 (1900.6403.42) is available.
1. NOTICE! Excessive tightening can damage the connectors.
Connect the stick holder to the RPC 1.85 mm connector of the R&S TSMS-
OMN70:
a) Carefully align the connector of the cable along a common axis.
b) Mate the connectors along the common axis until the male pin of the inner con-
nector engages with the female socket of the outer connector.
c) Turn the nut of the outer connector until the connectors are coupled.
d) Torque the nut to the specified limit using a calibrated torque wrench.
