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.
cables at the filter. Two of cables run to a teeconnector and one of the cables runs to the card cage. 7) Install the replacement filters in reverse order making sure that the mounting plates are firmly attached to the cabinet. Rebanding 3 MHz systems. SB II 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 filter is mounted horizontally at the top of the cabinet.
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.
