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.
