Rfwel Infra 20 ft Directional Antenna Kit for Cisco 819 LTE Router

Kit contents and purpose

This antenna kit bundles a 12 dBi directional Yagi antenna with a 20 ft 400-series low-loss coaxial cable, a lightning protection device, a jumper cable, and a pigtail for the Cisco 819 LTE Router. It is designed for installers who need to extend a single LTE antenna port outdoors for improved signal capture. The package includes all connectors and adapters required to mate the components with minimal signal attenuation.

What the bundled items change

The 400-series cable limits insertion loss to under .8 dB at 698 MHz and under 1.7 dB at 2700 MHz, preserving more gain over the run than thinner alternatives. The lightning protection device adds a safety layer for outdoor mounting, while the dedicated pigtail ensures a direct mechanical and electrical match to the router port. Together, the parts form a complete signal path from antenna to router without sourcing separate adapters.

Practical limits of the interface

The kit covers the 698 to 2700 MHz range, so it will not benefit services operating outside those frequencies. It addresses only one antenna port; a second kit is required to use both LTE ports on the router. The fixed 20 ft cable length sets the maximum separation between the antenna and the router unless additional cable and connectors are sourced separately. Directional aiming is necessary to realise the stated gain.
