Description

The Aironet short dual-band omnidirectional antenna is a compact, low-profile white dipole-style antenna for indoor Wi-Fi access points. It attaches directly to the RP-TNC connector of a supported AP and provides omnidirectional coverage in both the 2.4 GHz and 5 GHz bands, making it suited to indoor enterprise Wi-Fi deployments where a small, unobtrusive antenna is needed.

Gain is 3 dBi at 2.4 GHz and 5 dBi at 5 GHz, with a single RP-TNC port, 50 Ohm nominal impedance and a VSWR of less than 2:1. It is 3.3 in. (8.4 cm) long and does not articulate. This -RS variant adds self-identifying (SIA) circuitry with a built-in EEPROM, marked in purple, so a supported AP can detect the antenna type and gain automatically. The SIA function works only with the Cisco Catalyst 9120AXE access point. The non-SIA AIR-ANT2535SDW-R carries an orange marking instead.

It is a passive antenna and needs no power or licence. It is listed for use with Cisco Aironet 1600, 2600, 2800, 3600, 3700 and 3800 series access points and the Catalyst 9120AXE.

FAQs

Q: Does this antenna need a licence or subscription?
A: No. It is a passive antenna and requires no licence. The self-identifying function only operates with the Cisco Catalyst 9120AXE access point.

Q: Which access points does it work with?
A: It is listed for Cisco Aironet 1600, 2600, 2800, 3600, 3700 and 3800 series access points and the Catalyst 9120AXE. Cisco also lists it for the Aironet 1830 and 1850 and Catalyst 9115AX, 9120AX and 9130AX models.

Q: Does it need power?
A: No. It is a passive antenna and draws no power. It takes its signal from the RP-TNC connector on the access point.

Q: How does the -RS variant differ from AIR-ANT2535SDW-R?
A: The -RS version includes self-identifying (SIA) circuitry with a built-in EEPROM and a purple marking. The -R version is non-SIA and carries an orange marking.

Q: Is it for indoor or outdoor use?
A: It is designed for indoor use only, attached directly to an access point.
