SFFA
Compact far-field antenna, circular polarization, up to 70 cm
A far-field antenna of 90 x 60 x 20 mm and 35 g, with circular polarization and a read range of up to 70 cm. It reaches farther than the SNFA while staying small enough for counters and stations.
You verify or encode at a station or counter and need more reach than a pocket antenna, up to 70 cm, in a small part. 90 x 60 x 20 mm, 35 g, circular polarization.
Only the tag in front should answer? The SNFA reads to 15 cm. Counter reads up to 1 m? Choose the ANTNF1 or ANTNF0.

Questions we hear
How does it differ from the SNFA?
The SFFA is far-field, circular, and reaches 70 cm. The SNFA is near-field and reads to 15 cm. Both weigh 35 g and have one SMA female connector.
What band does it cover?
902 to 928 MHz, a little narrower than the SNFA (860 to 930 MHz). It is IP64, with 4 W maximum input.
