SAFETY NOTICE
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment
when installed as directed. This equipment should be installed and operated with fix-mounted
antennas that are installed such that the main lobe(s) of these antennas will have a minimum of 2
meters of separation distance between the antenna and all persons’ body during normal operation.
The amplifier can be mast mounted using the steel U-bolt included with the unit. Refer to the
drawing at the end of the manual for a cabling diagram. In outdoor applications, the amplifier must
be installed with the connectors facing downward. Use an open-end wrench to carefully tighten the
bolts using the included nuts. Take care not to over-tighten the bolts.
Alternately, the amplifier can be mounted to a flat surface using any of the mounting holes on the
brackets mounting flanges. However, for maximum reliability the connectors should be facing
downward.
It is very important to waterproof the RF connectors on the amp. However, it is recommended that
you do not tape the connectors until after all system tests have been performed. Be sure to use a
high quality weather resistant electrical tape and/or other water sealant method. Silicon sealants
are not recommended since they are hard to work with, do not ensure a 100% waterproofing of the
connectors and difficult to remove if ever necessary.
The picture to the left shows the amplifier in typical installation
shown with the YDI Model PT2421 Grid Dish antenna vertically
polarized. The location on the mast where the amplifier is
mounted is not important: provided that the connectors face
downward. (Note that when this picture was taken, the
connectors were not taped yet nor was the cable secured to
the mast.) Also, there is not need to plug or fill any of the
holes on the back of the amplifier enclosure. The housing is
designed such that these holes do not penetrate the inside of
the waterproof seal even though an initial inspection might
make you think otherwise.
If the tower or mast is adequately grounded and the U-bolt
makes good electrical connection to it, then there is no need to
provide additional grounding to the amplifier enclosure.
The DC Power Injector is not in a waterproof enclosure and must be protected from the weather. It
can be permanently mounted to a surface using the mounting flanges. If not mounted to a well-
grounded metal plate or bulkhead, then a separate ground strap will need to connect to the
grounding stud on the Injector.
Refer to the Typical Installation Detail drawing at the end of this manual for more information about
the installation.
