1.6 Connecting and Positioning of remote Antennae
In multichannel systems we recommend the use of the AT 70 A/B UHF antenna set consisting of
antennae, cables, antenna boosters and mounting kit.
1. Connect the receiving antennae to the corresponding antenna inputs and place the antennae to
the right and left of the receiver in the operating range where the transmitter is to be used. If
necessary change the position of the antennae to improve diversity reception.
2. The distance between the two receiving antennae should be at least 1 m.
3. The distance between transmitting and receiving antennae should be at least 3 m to avoid
overloading and interference between different channels. We therefore recommend installing the
antennae in a high position, especially in multi-channel systems.
4. If the operating range of the transmitters is
greater than the stage, the antennae can
be mounted vertically on the ceiling. The
distance between the two receiving
antennae should be approximately half the
total operating range.
Please note:
1. Install the receiving antennae in the same area as the transmitter.
2. To avoid interference do not install the antennae near digitally controlled components.
3. Keep a minimum distance of 0.5 m from metallic objects, including reinforced concrete walls or
pillars.
4. Do not bend the antenna cables at the antenna input, and ensure that they are not subjected to
undue stress.
