BT1500A SPECIFICATIONS

PALSTAR
The Palstar BT1500A Antenna Tuner is an American-made impedance
matching network.
The BT1500A optimizes the performance of your antenna and
transmitter by providing adjustable impedance matching using
balanced dual tandem roller inductors with a shunt capacitor that can
be switched to the input (transmitter) side or the output (antenna) side.
The BT1500A also measures the power and Voltage Standing Wave
Ratio (VSWR or SWR), which allows you to tune the SWR to the lowest
ratio possible for the selected transmission frequency.
A switch allows the user to choose Average or Peak metering. Also, a
Peak Hold function holds the peak reading for approximately 2
seconds for easier reading.
Front panel controls allow for selection between two ranges of variable
capacitance, and allow the shunt capacitor to be switched between the
input (transmitter) side (low Z, high pass) and the output (antenna) side
(high Z, low pass).
Tuning is achieved with the front panel controls. The Vernier
capacitor dial allows for fine tuning with precision and accuracy,
while the Inductor crank handle provides coarse adjustments.
The range of the power meter (300W/3000W) is selected
by a pusch button switch located on the front panel.
