Vor Inbetriebnahme sind die jeweiligen landerspezifischen Vorschriften zu beachten! 6 AD 3700 The AD 3700 is a broadband log-periodic directional antenna with integrated antenna booster for improving the transmission reliability in multi-channel systems. The AD 3700 can be connected to EM 3731, EM 3732 and EM 3732 Command receivers. Features • Log-periodic directional antenna • Amplification adjustable in 4 steps (up to 15 dB) to compensate for cable losses • DC powered from the receiver via the antenna cable • By-pass switch in case of power failure (ie: antenna then becomes a passive antenna) • LED operation indicator • Antenna booster housed in a rugged, splash-proof all-metal housing • Standard 3/8“ or 5/8“ mounting thread Delivery includes • AD 3700 broadband log-periodic directional antenna with integrated antenna booster • Instructions for use • Adjustment tool Operating elements . LED operation indicator . BNC socket, RF output (RF out) . Amplification selector . Mounting thread (3/8‘‘ or 5/8‘‘) LED operation indication LED color Selector position Amplification red bypass/-3 dB green +5 dB blue +10 dB white +15 dB . Notes • Keep the cable run between antenna and receiver as short as possible. • Observe a minimum distance of 5 m between antenna and transmitter. • Observe a minimum distance of 50 cm between antenna and metal objects (such as cross members or reinforced- concrete walls). • Observe a minimum distance of 1 m between antennas. • Orientate the antenna so that its direction of maximum gain is towards the transmitters. • 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).
