zBOOST INSTALLATION

This YXC-40K zBoost indoor coverage kit provides a complete solution for improving cellular voice and data signal 
within buildings up to 40,000 square feet. The kit provides the key components and design elements to allow 
professional installation over a wide variety of building conditions with proven technology from zBoost.  zBoost indoor 
coverage kits use a network of active amplifiers and antennas configured to provide optimum signal strength for 
multiple cellular providers while protecting the integrity of the carrier network using patented technology. 

OVERVIEW:

1.

Connect the system according to the diagram. Customer supplied RG-6 or RG-11 coax will vary in length

according to your particular installation.

2.

Orient the two Signal Antennas (YX021 and YX023) with the face of the panel antenna pointing toward the nearest

cell tower. The Signal Antennas should be mounted at least 3 feet away from any metal using the provided YX014
Mounting pole.  Ensure that the 18” coax jumper connected to each antenna  (YX021 and YX023) is connected to
the correct port on the YX015 combiner (i.e. YX021-CEL connected to CEL port).

3.

The YX044-F30 should be placed at the coax entrance to the building and grounded to a suitable connection.

4.

The YX841D Network Unit should be located indoors, as close to the antennas as possible, but away from the
other amplifiers. 

Warning

: Do not use this as a Coverage Unit (Part YX842D). If the YX842D and YX841D are

mixed, your zBoost system will not work.

5.

Several values of attenuators are included in the kit. The value used will depend upon signal strength and cable
lengths. Ensure that the attenuator connects from the CEL port of one YX015 to the CEL port of the other YX015.
Connect the attenuator on the PCS ports in the same way. A tool to calculate the final value needed can be found
in the Commercial Solutions Division section of our website when logged into your dealer account.

6.

Locate each of the eight YX842D Coverage amplifiers and associated YX052 ceiling mount antennas throughout

the desired indoor coverage area. (*Note 110 VAC is required for each YX842D amplifier). Each amplifier and
associated ceiling mount antenna will cover approximately 5,000 sq ft depending on outdoor signal strength.

IMPORTANT:

 Customer supplied RG-6 coax will vary in length according to your particular installation. The 

maximum length of RG-6 coax is indicated on the drawings. Should additional length be required, use RG-11 coax.

CHECK YOUR SYSTEM FOR PROPER OPERATION

YXC-40K Works with 800 MHz and 1900 MHz Devices
To verify proper operation of your zBoost system:

1.

Apply power to each of the YX842D Coverage amplifiers. Once power is connected, check that the LED light on

each YX842D is a solid green.  If the light on any amplifier is solid or flashing red, additional attenuation may be
required. Contact technical support for assistance at 1-800-871-1612.

2.

Using your cell phone or a YX699 signal meter, check various areas of your desired indoor coverage area for

improved signal strength.

3.

Place a phone call near one of the YX842D amplifiers and verify that you get a flashing green LED light on the
nearest YX842D.

4.

If the Signal Light does not flash green, but you are experiencing improved signal strength, your system is still
operating property. If the signal light does not flash green and you are not experiencing improved signal strength,
contact our technical support for assistance at 1-800-871-1612.
