  • Page 13: Operating Environment Recommendations

    We do not recommend installation in rooms with high humidity, dusty places or other aggressive conditions. • Although it is expected that a DB4004 will be installed close to exciters (or transmitters of even higher-power!), please practice reasonable care and common sense in locating the unit away from abnormally high RF fields.

  • Page 14: Installation Specifications And Precautions Regarding The Rf Environment. Antenna Consider- Ation

    The typical RF output level of such sources is too high for the normal operation of the DB4004 receiver. We strongly recommend using external RF attenuators with attenuation value between 20 – 90dB for reaching optimal RF output level in the 55-60 dBµV range.

    Such antenna besides improving the signal strength, will contribute in eliminating the multipath distortion. A bargraph indicator used in DB4004 allows measuring the strength of the signal being received, where the rule “the more the better” is in force. To reach this indicator, activate LEVELS menu.

  • Page 20: Co-Channel Interference

    Another thing which would result in mutual interference between the broadcasting stations is poor frequency planning. The inherent broad bandwidth of the DB4004 receiver is vulnerable from stations working on the nearby frequencies, where signal strength will be the most important factor – the stronger the interfering station, the stronger the interference effect.
