Recommendations for using antennas
Click the two options above to learn more about using rod antennas and re-
mote antennas.
Rod antennas (included in the delivery)
The EM 6000 can be operated throughout the entire frequency spectrum
with the UHF rod antennas included in the delivery.
For optimum range and reliability, we recommend using remote antennas
because antennas directly on the device do not have the optimum distance
from each other and cannot be aligned with the transmitters.
You can find more information about remote antennas under „Remote
antennas“.
Remote antennas
We recommend using remote antennas instead of the rod antennas sup-
plied. Remote antennas achieve better reception.
The antennas are connected to the receiver using coaxial cables and
mounted on a conventional microphone stand. They should be positioned
so that at least one antenna always has a free line of sight to the transmit-
ters. The distance between the antennas should be approx. 1 to 2 m (3.3 to
6.5 ft) to ensure a good diversity response from the receiver.
For information about the antennas and accessories recommended
by us, see „Antennas and accessories“.
Active vs passive antennas
Passive antennas do not require a power supply and do not have any elec-
tronics. Active antennas have a fitted amplifier and require a power supply.
If you are using active antennas:
▷ Activate the power supply for external antenna amplifiers in the
EM 6000 system menu
See „System -> Booster Feed menu item“ under „System menu item“.
If you are using passive antennas, you can use them as active antennas by
using an external antenna amplifier.
General recommendation
Generally, passive antennas should be used. The EM 6000 is designed for
this type of application.
Active antennas are used to balance the attenuation in the coaxial cable
and supply the receivers with a sufficiently strong signal. However, this is
not required with the usual cable lengths of up to approx. 10 m (32 ft).
When active antennas are used incorrectly, there is a risk of overloading
the receiver. In addition, noise signals are always amplified as well as the
wanted signal, which eliminates the benefit to the levels.
Types of remote antenna
Antennas with different types of pick-up pattern are available:
