Notes
y Keep the cable run between antenna and receiver as short
as possible.
y Observe a minimum distance of 5 m between antenna and
transmitter.
y Observe a minimum distance of 50 cm between antenna
and metal objects (such as cross members or reinforced-
concrete walls).
y Observe a minimum distance of 1 m between antennas.
y For optimum reception, always align the antennas
vertically.
Suitable cable types and
corresponding amplification settings
Depending on the cable length, you have to adjust the
amplification using the selector (see diagram on page 2).
