1.0 Unpacking:

Remove the EkoMiniTM repeater and the external power supply from the box. If an
EkoMini repeater kit was purchased, donor and server antennas should have been
received in separate shipping containers.

2.0 Additional Parts Needed for Installation:

Since every installation is different, other parts may need to be provided by the
installer:

• Donor antenna, unless an EkoMiniTM kit was purchased.

• Server antenna(s), unless an EkoMiniTM kit was purchased.

• 50 ohm Coaxial power splitter, if more than one server antenna is

needed.

• 50 ohm ½” flexible coaxial cable, plenum rated if required by building
code.

• Type N male connectors (or DIN 7-16, depending on the antenna
connector option)

• Mounting hardware for the donor antenna

• Weatherproofing compound

• Other miscellaneous installation items

3.0 Pre-setting the Configuration Switches:

The EkoMiniTM is shown in Figure 1. It has a set of eight configuration “DIP” switches
located under a small removable panel. See Figure 2. For many installations, these
switches are set properly at the factory. However, they can be verified or changed
using this procedure:

• Remove the small switch panel with a Phillips head screwdriver.

• The switches are numbered 1 through 8, as shown in Figure 2

below. They can be turned “on” or “off” using a small screwdriver or
a bent paper clip. Note that each switch is “off” when it is pushed

“up” toward the repeater mounting flange.

• Position each of the eight switches as described below.
