The transmitter can be powered from any external DC source of 6 to
18 Volts at 200 mA maximum or from the provided 12 Volt power
supply with a locking power connector. The unit has an internal
self-resetting fuse and reverse polarity protection.
The PTX-3 is housed in a machined aluminum case with a tough
electrostatic powder coating. The front and rear panels are anodized
aluminum with laser etched engraving. The included antenna is a right
angle, ¼ wavelength monopole with a BNC connector, constructed of
polymer coated flexible steel cable.
These features, along with 250 milliwatt RF output power and a wide
range of selectable audio input types and levels, make the PTX-3 an
excellent choice for IFB and other applications where extended
operating range is required.
