Antennas

PG - A2 Integrated UHF Antenna

PG - A1 Dual-Frequency/Dual-Constellation Antenna

The PG-A series of high-precision

GPS antennas is an exciting addition

to the complete line of Topcon

GPS products. These GPS micro-

centered antennas are available as

either a standard dual-frequency,

dual-constellation antenna (PG-A1)

or with the addition of integrated

UHF (PG-A2).

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.

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.

CR - 3 Zero-Centered Choke Ring GPS Antenna

The CR-3 is a zero-centered L1/L2 reference base station

antenna mounted on our single-depth choke ring. It

features a fully weatherproof design with 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

32.6cm and height of 10.1cm (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.

Topcon continues its lead in GPS technology with the compact

and ultra-rugged PGA antennas. These high precision GPS micro-

centered antennas are available as either a standard dual-

frequency, dual-constellation antenna (PG-A1) or with the addition

of integrated UHF (PG-A2).
