area that would otherwise be outside the antenna's receiving
angle.
The SRA 1 directional antenna uses no active circuitry and the-
refore requires no power supply. However, its circuitry has been
designed to "neutralize" supply voltages so you can connect
the SRA 1 even to an antenna input or output that provides a
supply voltage for a booster (e.g., PS 81).
To connect the antenna to the SST 1 transmitter of the IVM 1
In-ear Monitor System, use the optional MK A 5 antenna
cable only. Longer cables have a higher attenuation that would
reduce the radiated power considerably.
1. Use an antenna cable with BNC connectors. (Refer to sec-
tion 1.6 Optional Accessories.)
2. Plug the connector behind which you fixed the ferrite core
into the BNC connector on the front disk of the antenna.
Make sure that at least the first 20 cm (8 in., equivalent to the
antenna diameter) of the antenna cable will hang down ver-
tically (refer to fig. 1). Otherwise the antenna's polar pattern
would change.
3a. Connect the other end of the antenna cable to the antenna
output of the SST 1 transmitter. Refer to the instruction
manual of the IVM 1 In-ear Monitor System.
3b. Connect the other end of the antenna cable to the antenna
input of your receiver or Power Splitter.
You can connect the antenna to the following UHF equip-
ment: SR 300 and SR 81 receivers, PS 81 Power Splitter.
Refer to the instruction manual of the appropriate equip-
ment.
Fix the supplied ferrite core to the cable
immediately behind one of the two con-
nectors (see fig. 11).
The ferrite core keeps the antenna's polar
pattern symmetrical and prevents intermodu-
lation when using several antennas at the
same time.
