GENERAL DESCRIPTION
Signal boosters extend radio coverage into areas
where abrupt propagation losses prevent reliable
communication. This system receives an RF sig-
nal, raises its power level, and couples it to an
antenna or leaky (radiating) coaxial cable system
so that it can be re-radiated. No frequency transla-
tion (conversion) occurs with this device.
The one-way signal booster model 60-96-00400-
G1 (shown in figure 1) is a broadband, bidirectional
single branch system which passes frequencies
from 929 to 932 MHz. The system covers a 3 MHz
passband width (factory set) and uses linear RF
active amplifiers, filters, and DC power sources to
adequately boost and re-radiate the passband sig-
nals.
The output level of any signal passing through a
signal booster is determined by the systems gain
specification. All signals passing through a prop-
erly operating signal booster are amplified by the
Figure 1: Inside view of the model 60-96-00400-G1 one-way signal booster system.
