Typical Gain Curve
TPAS-100 Two
Port Splitter
The TPAS-100 is
intended to be used with FCC type MADF systems which have two issues
as installed.
One: The RF
multicoupler used at the dash radio antenna - although it has good
gain and noise performance for use with the monitoring receivers and
scanners, it has a low frequency cut off of 30 MHz. Therefore no RF
signal from the Stico antenna gets through to the vehicle’s radio
for the AM band.
Two: The radio
used for the DF system is the Icom R-8500 which has a separate input
for HF frequencies below 30 MHz. To be able to DF below 30 MHz you
need to provide RF signal to this separate port.
A TPAS-100
can be used to solve either these problems.
It has a RF
protected input so that static and RF over load will not destroy the
down stream systems. It provides good noise performance and some
gain with good isolation between both of the equal outputs so that
they will not be interfered with by the tuning of the receiver or
other items served by the multicoupler. These same characteristics
also make it a good amp/splitter for the two band inputs of the Icom
R-8500 radio.
As an RF input
Limiter it will protect the receivers and multicouplers from being
destroyed by too much input power or static charge buildup on the
antenna.
As an Icom
splitter it makes DF'ing possible below 30 MHz.
The TPAS-100
system will protect the receiving systems on a continuous basis with
a 50% duty cycle on the transmitter by meeting the following
conditions. The transmitting and receiving (DF) antennas should not
be placed closer than the following spacing:
For a 5 watt transmitter the minimum
spacing should be 1 feet
For a 25 watt transmitter the minimum
spacing should be 3 feet
For a 40 watt transmitter the minimum
spacing should be 5 feet
