GENERAL DESCRIPTION
These instructions are for rebanding 800 Mhz Signal Booster II systems in the field. Caution should
be taken not to drop the filters or sharply bump the
tuning rods located on the top of the filters, doing
so could result in de-tuning of the filters. The conversion process consists of replacing the original
filters with new ones, adding a signal sampler if
required, replacing the Tee-connector as well as
several critical length cables. If there are any questions or concerns regarding the installation of this
rebanding kit, please contact the customer service
department at (716) 549-4700 extension 5044.
Types of 800 MHz SB II Re-banding kits
There are two types of rebanding kits available for
the 800 MHz SB II system. Which type of kit you
use will depend on whether your unit originally
shipped from the factory with 18 MHz bandwidth
duplexer assemblies (called 18 MHz systems) or
with either 3/5/10/15 MHz bandwidth preselectors
(called Non-18 MHz systems). The correct type of
rebanding kit to use for your particular SB II system
will be determined by the TXRX Sales Department
at the time you place your order for the re-banding
kit.
Procedure for Non-18 MHz Systems
Re-banding kits for systems that originally left the
factory as Non-18 MHz systems will consist of
replacement filters which have the new desired
bandwidth, new tee-connectors, and several criti-
cal length cables. The filters are pre-tuned at the
factory so the position of the tuning rods should not
be changed. The conversion process consists of
simply replacing the old filters, tee-connectors and
cables with the new ones. A simplified block diagram for a Non-18 MHz SB II system is shown in
Figure 1. The parts to be swapped out are indicated.
All work should be performed by a qualified electronics technician familiar with the communications
system. Refer to the system drawings at the back
of this manual as a guide to the correct placement
of assemblies and cables. Follow the instructions
listed below in a step-by-step fashion.
1) Open the signal booster enclosure and turn
OFF the AC power. Disconnect or turn OFF any
battery back-up DC input.
2) Disconnect three cables from the two filters on
the right side of the cabinet. Disconnect the
cables at the filter. Two of cables run to a teeconnector and one of the cables runs to the
card cage.
3) Disconnect the signal sampler from the filter.
The right side filters should be ready for
removal at this point.
4) Disconnect three cables from the two filters on
the left side of the cabinet. Disconnect the

NOTE
filter is mounted horizontally at the top of the
cabinet. If you are rebanding a 3 MHz system to
a higher bandwidth system then the extra filter
will be removed permanently. Disconnect and
discard the cable between the left side preselector and the extra filter.
5) Disconnect the signal sampler from the left side
filter. The two left side filters should be ready for
removal at this point.
6) Remove the screws which hold the filter mounting plates to the cabinet mounting panel and
remove the filter assemblies from the cabinet.
Use care when removing the filters so as not to
damage any of the cables that are dangling in
the cabinet.
NOTE
systems with an original 3 MHz
bandwidth use an extra filter in
series with the preselector on the
left side of the cabinet. This extra

extra filter should be removed from
the cabinet first to provide additional room to maneuver the
remaining filters out of the cabinet.
8) Reconnect three cables to the two filters on the
right side of the cabinet. Reconnect the cables
at the filter. Two of the cables run to a tee-connector and one of the cables runs to the card

11) Reconnect the signal sampler to the left side
filter.
12) Verify that all filters and cables have been rein-
stalled properly, the booster should look

kit.

tion.

Procedure for 18 MHz Systems
Re-banding kits for systems that originally left the
factory as 18 MHz systems will consist of replacement filters which have the new desired bandwidth,
new tee-connectors, several critical length cables,
as well as a signal sampler. The filters are pretuned at the factory so the position of the tuning
rods should not be changed. The conversion process consists of simply replacing the old filters
(duplexer assemblies) with new filters, adding teeconnectors, cables, and signal samplers. In addition, the circulators will be attached to the cabinet
mounting plate instead of the duplexer assemblies.
A simplified block diagram for a 18 MHz SB II system is shown in Figure 2. Note that the original
duplexer assembly has the tee-connector, critical
length cables, and signal sampler built-in. The rebanding kit includes these parts as individual
assemblies.
All work should be performed by a qualified electronics technician familiar with the communications
system. Refer to the system drawings at the back
of this manual as a guide to the correct placement
of assemblies and cables. Follow the instructions
listed below in a step-by-step fashion.
7) Install the tee-connectors and associated
cables to the bottom connectors on the right
and left side filters. Refer to the appropriate system drawing in the rear of this manual to make
sure you have the correct cables going to the
correct ports. These are length sensitive cables
so it is important to connect them correctly.
Install the 2 thru-hole connectors at the bottom
of the cabinet.
8) Attach the card cage to the right and left filters
with the supplied cables.
9) Attach the signal samplers to the filters as
shown in the drawing.
10) Install the two circulators on the cabinet mount-
ing plate as shown in the drawing.
11) Install cables from the circulators to the power
amps and from the circulators to the signal
samplers.
12) Verify that all filters and cables have been
installed properly. The booster should now
look like the system drawing.
1) Open the signal booster enclosure and turn
OFF the AC power. Disconnect or turn OFF any
battery back-up DC input.
2) Disconnect and discard the 3 cables connected
to the right and left side duplexer assembly.
Including the thru-hole connectors at the bottom
of the cabinet.
3) Disconnect and discard the remaining cable
connected to the right and left side circulators.
4) Remove the mounting screws for the right and
left side duplexer assemblies and remove them,
with the attached circulators from the cabinet.
Use care when removing the duplexer assemblies so as not to damage any of the cables that
are still in the cabinet.
5) Remove the circulators from the duplexer
assemblies, they will be re-used.
6) Install the right and left side replacement filters
(two on each side) making sure that the mounting plates are firmly attached to the cabinet.
13) Energize the booster and verify correct operation.
