The Palstar AT5K Antenna
Tuner is an American made im-
pedance matching network that
can provide unbalanced and
balanced output with a power
rating of 3500 watts (single tone
continuous) and 5000 watts
PEP at certain Z ranges (p.14).
The AT5K T-matching network
utilizes a 1:1 unbalanced to bal-
anced transformer in the input of
the network. When the network
is properly tuned, a 50 Ohm im-
pedance will be presented to
both the input and output of the
balun for maximum efficiency.
The AT5K optimizes the per-
formance of your antenna and
transmitter by providing adjust-
able impedance matching using
a T-type circuit configuration.
The AT5K also measures the
power and Voltage Standing
Wave Ratio (VSWR) which al-
lows you to tune the SWR to the
lowest ratio for the selected
transmission frequency.
Integrated into the AT5K is a
frequency-compensated lighted-
dial dual-movement SWR me-
ter. The meter features the abil-
ity to read True Active Peak and
Peak Hold.
Designed to handle both Bal-
anced line feeds and Coax
feeds the AT5K features a front
panel mounted switch to select
between feeds.
Tuning is achieved with the front
panel mounted controls. The
Vernier capacitor dials allow for
tuning with precision and accu-
racy, while the Inductor crank
handle facilitates coarse adjust-
ments.
