1.10 Connecting and Positioning of remote Antennae
In multichannel systems we recommend the use of the AD 707 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. Diversity reception is improved when the
antennae are vertical or slightly tilted.
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.
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.

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.
