The PG-A1 is a precision dual-frequency, dual-constellation antenna featuring precision micro center technology and an integrated ground plane to help eliminate errors caused by multipath. The PG-A1 was designed to accompany the Topcon modular receivers such as the Legacy-E, Legacy-H and Odyssey-RS.

PG-A2                                                                PGA-1 & PGA-2 Brochure           

Another World's First innovation from Topcon, the PG-A2 is the first antenna to provide both dual-frequency dual-constellation satellite tracking and integrated UHF antenna for maximum communication range, all in one compact, durable design.  The PG-A2 is a precision dual-frequency, dual-constellation antenna with integrated UHF and featuring precision micro center technology and an integrated ground plane to help eliminate errors caused by multipath. The PG-A2 was designed to compliment the Odyssey-E integrated receiver, UHG radio and Windows CE controller.

The CR-3 is a zero centered L1/L2 reference base station antenna mounted on Topcon's single-depth choke ring. The fully weatherproof design has an optional cone environmental cover. The CR-3 choke ring antenna brings proven technology and reliability to high-end reference station systems.

It weighs about 3.7 kg with a diameter of 32.6 cm and height of 10.1 cm (without cone cover). The included LNA accepts voltages from 2.7 to 12 volts and has 32 ± 2dB of gain. Output impedance of the antenna is 50 Ohms. Frequency ranges are from 1565 to 1620 MHz and 1217 to 1260 MHz and the antenna has N type connectors.

CR-4 ZERO CENTERED CHOKE RING     Specifications

The CR-4 antenna and the Topcon antenna cables are equipped to endure the harshest of environments.  This JPL spec choke ring antenna is designed for highly efficient multipath reduction.  It is available with or without the environmental cone cover.
