3. Amplifier Kit
Each Amplifier Kit Includes:
• Bi-directional remote mounted
amplifier
• DC Power Injector
• 12 VDC, 110/220 VAC Power Supply
• Stainless Steel U-Bolts and mounting
bracket for amp
• Installation Manual
The following options are also available and must be ordered separately:
CAB-DC DC power cable with 2.1mm plug to flying lead 3 feet long. Used when
the customer provides their own 12 VDC power for the DC injector or
amp.
Dual-DC Option to add second power jack on DC injector to enable one 12 VDC
PS that comes with the amp to power both the Injector and the radio or
AP. (Requires a DC jumper cable. See below).
DC-2.1-2.1 DC jumper cable that connects a radio modem or Access Point to the
second DC power jack on the DC injector box. Radio devices must
have a 2.1 mm ID power jack and operate on 12VDC.
DC-2.1-2.5 Same as above except used for radios and Access Points that have a
2.5 mm ID barrel jack on them.
4. Installation and Cabling Instructions
FCC Notice
To comply with FCC part 15 rules, the proper version of the amp must only be used in
systems that have been FCC certified. The system must also be professionally installed to
ensure compliance with the Part 15 certification. It is the responsibility of the professional
installer to ensure that certified systems be deployed in the United States (or where FCC
rules apply). The use of the amplifier in any other combination (such as co-located
antennas transmitting the same information) is expressly forbidden in accordance with
FCC rules CFR47 part 15.204. Please visit our web site (www.ydi.com) to see the
systems currently certified by the FCC.
Several key factors unique to their particular installation determine the power level at the input of the
amplifier. The most important consideration is the cable loss in the transmission cable between the
radio and the pole mounted amp. It is important that the installer understand these and other
factors when installing the system.
If you are not familiar with determining power levels within the transmission system, YDI engineers
will assist you in planning your system including selecting the proper cable and antenna required.
