PRO-ISO-PHY-TETRA-ELW
Two-TETRA-Station Combiner with DMO
DESCRIPTION
The PRO-ISO-PHY-TETRA-ELW combiner provides
the possibillity of connecting up to two TETRA radios into
one common antenna.
ETSI compliant connection of two digital radios.
The PRO-ISO-PHY-TETRA-ELW supports Direct Mode Operation (DMO),
giving the TETRA mobile radios the ability to communicate
with each other without using the TETRA infrastructure
(the radios need to stay within coverage of each other).
The PRO-ISO-PHY-TETRA-ELW is the successor to the
PRO-MIX-PHY-TETRA-ELW-N-2RXI.
The PRO-ISO-PHY-TETRA-ELW has improved isolation between
the ports - more than 60 dB - and lower insertion loss.
The use of high-quality system components such as highly selective
helical duplex filters and high-performance isolators provides high
isolation and secure communication.
Built-in high-pass filter, for attenuating interference from
2m (150 - 174 MHz) and 4m (74 - 87.5 MHz) bands.
The smallest and most compact design on the market.
Suitable for both stationary and mobile use.
Also available in tray for 19" rack mounting.

PRO-ISO-PHY-TETRA-ELW-N(f) 210001983
* Compatible DMO-modes
The PRO-ISO-PHY-TETRA-ELW is compatible with the following
DMO modes in 406 - 410 MHz band:
- DM-MS
- DM-REP (1A, 1B and 2)
- DM-GATE
- DM-REP/GATE (1A, 1B and 2)
NOTE: DMO mode DM-REP 1B and 2 / DM-REP/GATE 1B and 2 requires
duplex spaced RF carriers, which is not included in this equipment.
