Antenna Selection Guide

Finding the right antenna for your application should be easy. Calian’s simple, three-step antenna selection guide allows you to quickly specify the fundamental antenna requirements for your situation to quickly narrow down your antenna options.

Step 1

Coverage and L-Band

Step 2


Step 3

Amplifier Gain

Step 1 – Choose Frequency Coverage and L-Band

The first step to choosing the right antenna is defining which signal frequency bands from which satellite constellations your receiver requires. Calian’s broad antenna selection supports GPS, GLONASS, Galileo, BeiDou, QZSS and NAVIC GNSS constellations, Iridium Satellite Communications, and L-Band connection services.

Please select one of the following frequency options:

Single Band GNSS

Antennas that receive upper signal bands. Three Configurations are available:

• L1

• L1  G1

• L1  G1  E1  B1

Dual Band GNSS

Antennas that receive select lower GNSS bands in addition to the upper band. Four configurations are available:

• L1/2  G1/2  E1  B1

• L1/2  G1/2/3  E1/5b  B1/2

• L1/5  G1  E1/5a  B1/2a

• L1  G1  E1/6  B1/3  L6

Triple Band GNSS

Antennas that receive many lower GNSS bands in addition to the upper band. Two configurations are available:

• L1/2/5  G1/3  E1/5ab  B1/2/2a

• L1/2/5  G1/2/3  E1/5b  B1/2

All GNSS Signals

Antennas that receive signals across the full GNSS spectrum.


Antennas that support Iridium.

L-band correction services provide Precise Point Positioning (PPP) corrections to a receiver. This mitigates measurement errors and position jumps to help increase system accuracy.

Step 2 – Select Mount Method

In order to support a wide variety of applications, Calian provides many mounting options across the entire antenna range.

Please select one of the following mounting options. You can also   Skip this step

OEM / Embedded

For applications where the antenna is integrated into the components of a larger system.

Surface Mount

Surface mount options include magetic, adhesive and direct screw


For through-hole mounting

Standard Survey Mount

For universal compatibility with survey mounting systems.


For universal compatibility with NMO mounting systems.

Step 3 – Specify Amplifier Gain

Most Tallyman GNSS antennas have an integrated Low Noise Amplifier (LNA), which amplifies the received GNSS signals, without significantly degrading the signal quality. GNSS antennas without an LNA, and also Iridium antennas, are all considered “Passive” antennas, transmitting the original signal amplitude to the receiver. If you are unsure of your gain requirement, please feel free to skip this step.

Please select a minimum antenna amplifier gain level
