Avlex AT-90W Wideband Extension Antenna - Manual (Page 2)

! When using the RX connector , please be aware that the inside wire of antenna
cable can not touch the case itself to avoid the short circuit. This is due to the
connection socket equipping with the 8VDC power.
! RX connector socket is only for the receiver and hence it can not apply to the
transmitter. If doing so, it may cause the damage to the transmitter.
! The shorter length of coaxial cable is the better when it comes to connect the TX/RX
socket to the receiver. It is recommended to remain the cable length within 20m to
avoid the reception signal decrease too much. However the coaxial cable length has to
keep over 20m when using the RX connector , or the signal saturation would occur
due to the over-gain from booster then lead to the anti-interference deterioration.
Hence it will improve the sensitivity by using RX connector , but meanwhile it
requires being aware the anti-interference feature may deteriorate.
The product is a 2-way directional antenna for professional receiving and
transmission within UHF range. Optimized for 480MHz ～ 1000MHz, it has a 4 ～ 6dBi high
directional effect which is ideal for the environment that needs specific direction usage.
The most unique feature of AT-90W is it can be connected to transmitters and receivers
directly. Besides, it is built with a 12dB high gain booster specifically for long distance
receiving. The power of the amplifier is derived from the coaxial cable connected to
MIPRO AD-707/AD-707a antenna divider or ACT-Series receivers. The two ways offer
users an option to reach a maximum effect according to actual system requirement. AT-
90W is ideal for both indoor and outdoor usage.
RX Antenna Cable Connector: The connector is installed with a 12 dB-booster. It is
needed to have at least 20m antenna cable and connected to the receivers or
antenna dividers which offer 8V DC output power.
TX/RX Antenna Cable Connector: Transmission output or antenna input connector,
0dB gain, can be connected with maximum 20m cable or antenna to transmitters or
receivers.
Swivel Adapter Bracket: Can be setup on any 35 mm tripod or mounted on to
MIPRO's MS-90 wall-mounting kit.
Power LED Indicator: The LED light with the 8V DC power input from receivers and
the booster will be started at the same time.
Holding Knob: To hold antenna's direction. Generally, loose the screw to adjust
antenna direction and tighten the button to hold the direction when fixed.
! TX/RX antenna cable connector can be connected with 20m antenna cable to MI-
808T transmitters, AD-808 antenna combiner. This connector can also be connected to
ACT-Series receivers or AD-707/AD-707a antenna dividers.
! RX connector has to adopt the antenna cable which the length is over 20m to connect to the
ACT receiver and AD-707/AD-707a. While switching on the receiver or antenna divider AD-707/AD-
707a, it is required to check the power indicator of AT-90W. If the indicator does not light up, it
means the built-in booster is failed.
! Adjust antenna's directional angel to proper position (see illustrations below) for best
performance result.
! Set the base on any 35 mm tripod or on top of MIPRO's MS-90 wall-mounting kit.
When done, tighten the knob (see illustrations below)
