PRO-PHY85-2

2-Channel Hybrid Ring Combiner for 85 MHz Transmitters

DESCRIPTION

Combining two transmitters or receivers on the same antenna.

Better utilization of good antenna position.

Two antennas on the same transmitter or receiver.

Combining two signal generators.

The only combining option with very small TX-TX frequency spacing.

60 W load supplied (other loads or no load as option).

MECHANICAL

TEMP. RANGE –30° C → +60° C

CONNECTORS N-female (other types as option)

DIMENSIONS (L x W x H) 216 x 89(incl. conn.) x 42 mm (excl. load)

WEIGHT Approx. 700 g (excl. load)

*The isolation between the TX ports is directly dependent on the terminating

SWR on the antenna port. With an antenna load SWR = 1.5, the isolation

between the two TX ports will be reduced to 20 dB @ 5 MHz bandwidth.

**The SWR of the load’s should be < 1.1! The load should be able to

dissipate 1/2 of the total input power.

E.g.: With 50 W input in total for the two channels, the load should be able

to dissipate 50 W x 1/2 = 25 W.

PROCOM A/S reserve the right to amend specifications

without prior notice.
