Connecting antennas

To connect the supplied rod antennas:

Connect the antennas to the two antenna inputs on the receiver as shown in the figure.
Slightly angle the antennas to the left and right as shown in the figure.

If you are using more than one receiver, we recommend using remote antennas and possibly the EW-D ASA antenna splitter (EW-D ASA antenna splitter).

To connect remote antennas:

Connect the antennas to the two antenna inputs on the receiver as shown in the figure.
Observe the specified minimum spacing.
Observe the specified minimum spacing to the transmitters.
*Recommended antennas:
- ADP UHF | 470 – 1075 MHz
- AD 1800 | 1400 – 2400 MHz
- AWM UHF I | 470 – 694 MHz
- AWM UHF II | 823 – 1075 MHz
- AWM 1G8 | 1785 – 1805 MHz
If you are using more than one receiver, we recommend using remote antennas and possibly the EW-D ASA antenna splitter (EW-D ASA antenna splitter).

To cascade the receiver:

The EW-DX EM 4 Dante receivers have a built-in antenna splitter. This enables you to cascade up to four receivers. This makes it possible to use 2 antennas/antenna boosters for up to four receivers. All receivers use the same booster frequency range.

Connect two antennas as described above.
Connect the RF out socket of the first receiver to the corresponding RF in socket of another receiver using a short antenna cable.
Proceed as described in the previous step for a total of four receivers.
