Napco SLE-ANTEXT50 Optional Extended Antenna with 50' Ultra Lowloss Premium Cable and Complete Hardware, Pole Mount Included

Extend and stabilize cellular connectivity for alarm, security and remote monitoring systems with the Napco Security Technologies SLE-ANTEXT50 optional extended antenna. This omnidirectional, multi-band high-gain antenna is engineered to increase transmission range and signal sensitivity for StarLink Cell/IP communicators and most other brand radios, delivering reliable LTE and 4G performance where it matters.

The SLE-ANTEXT50 ships with a 50' ultra low-loss premium LMR-type cable and a complete mounting kit — including a pole-mount L-bracket and stainless steel U-bolts — so you can place the antenna at the highest, most effective elevation without signal loss. Its marine-grade, UV-stable enclosure and a low VSWR (<1.5:1) ensure consistent radiated power and long-term outdoor durability. Ideal for alarm communicators, surveillance gateways and remote security installations, this antenna reduces false alarms and improves alarm delivery success across cellular bands.

For installers and integrators seeking a dependable, easy-to-fit upgrade to existing cellular alarm systems, the SLE-ANTEXT50 is a practical solution. Add one to your next security, surveillance or monitoring deployment to maximize cellular coverage and reliability.
