The upgraded kits feature improvements to the mast, mount, power system and software. The pole mast system is redesigned for simpler setup and takedown. The mounting bracket is stronger to reduce the potential for vibration. The tripod battery is an improved design that powers both the GPS receiver and the radio modem, and the new universal power adapter kit supports worldwide operations.
PDLLPB kits are available for all major GPS receiver makes and models. A full range of choices is available for frequency, RF power, channel spacing, and battery and mount options.
