Connection And Mounting Of Remote Antennæ - Sennheiser EM 3031-U Instructions For Use Manual

6 Connection and mounting of remote antennæ
If the receiver position is not the best antenna position for optimum reception, you can use remote
antennæ. These are available as accessories.
The best reception quality is obtained with the Sennheiser A12 AD-UHF active antenna. Antenna
and receiver can be connected with a RG 58 co-axial cable. Ready made up antenna cables from
Sennheiser are available as accessories with lengths of 1 m, 5 m and 10 m (see chapter 20)
Attention!
To supply the antenna booster integrated in the A12 AD-UHF active antenna, a
direct voltage (which can not be switched off) is output via the antenna sockets. If
you use antennæ from other manufacturers instead of the A12 AD-UHF, take into
account that these must be installed with direct voltage decoupling, i.e. isolated.
The output voltage supply is short circuit-proof, but an active antenna connected
to this supply increases the power consumption of the overall device.
Notes on mounting the antennæ (which absolutely must be adhered to)
Position antennæ in the same room in which the transmission takes place!
Maintain a minimum distance of 1 metre from metal objects (including walls of
reinforced concrete)!
Maintain a minimum distance of 1 metre between the receiving antennæ!
