Questions & Answers
What is the Cisco AIR-ANT2451V-R=?
The Cisco AIR-ANT2451V-R= is a dual-band omnidirectional antenna with RP-TNC connector designed for 2.4 GHz (3 dBi) and 5 GHz (3.5 dBi) wireless deployments.
Which frequency bands does AIR-ANT2451V-R= support?
It supports the 2.4 GHz band at 3 dBi gain and the 5 GHz band at 3.5 dBi gain for dual-band coverage.
What connector does the antenna use?
The antenna features a reverse-polarity TNC (RP-TNC) female connector compatible with most Cisco access points and bridges.
Is the AIR-ANT2451V-R= omnidirectional?
Yes, it provides 360° horizontal coverage ideal for uniform signal distribution in indoor or outdoor settings.
Which Cisco devices are compatible with this antenna?
It is compatible with Cisco Aironet and Catalyst series APs and outdoor bridges featuring RP-TNC female ports.
What coverage range can I expect?
Typical coverage extends up to 50 meters indoors and 150 meters outdoors, depending on environment and client radios.
How do I mount the AIR-ANT2451V-R=?
Use the included mounting bracket to secure the antenna vertically on walls or poles for optimal signal propagation.
Can I use this antenna outdoors?
Yes, it is designed for outdoor use with UV-stable housing, but ensure it is mounted under minimal direct water exposure.
Does this antenna support MIMO?
It supports single-element operation; for full MIMO benefits, install one antenna per spatial stream as recommended.
How does antenna gain impact performance?
Higher gain focuses energy horizontally, extending range but narrowing vertical coverage—ideal for broad, flat areas.
Can I extend the antenna with a cable?
Yes, you can use low-loss RP-TNC extension cables, but keep total cable length under 3 meters to minimize signal loss.
What materials and durability features does it have?
The antenna uses UV-resistant ABS plastic and corrosion-proof metal hardware for long-lasting outdoor reliability.
Do I need special configuration for this antenna?
No special software configuration is required; simply attach it to the RP-TNC port and adjust your AP’s transmit power if needed.
How should I optimize antenna placement?
Position the antenna at least 2 meters above obstructions and away from large metal objects for best line-of-sight performance.
What is the typical warranty period?
Cisco provides a limited lifetime warranty on this antenna, subject to the standard Cisco warranty terms and conditions.
How do 2.4 GHz and 5 GHz performance differ?
The 2.4 GHz band offers better wall penetration and longer range, while 5 GHz provides higher throughput and less interference.
Why choose the AIR-ANT2451V-R=?
Its dual-band omnidirectional design, rugged build, and easy RP-TNC installation deliver reliable, flexible coverage for enterprise WLANs.
