Antenna kit for EnGenius cordless systems

This external antenna kit is designed for EnGenius cordless phone systems including FreeStyl 1, DuraFon 1X, 4X and PRO, EP-436, EP-490, SN-900 and SN-920. It provides a high-gain omnidirectional antenna suitable for indoor or outdoor installation. The kit extends wireless coverage for compatible handsets and base stations.

20 metre LMR400 cable with pre-fitted adapters

The bundle includes 20 metres of LMR400 low-loss coaxial cable, approximately 65 or 66 feet, with reverse-thread TNC and N-type adapters already connected. This cable length allows flexible antenna placement away from the base unit while minimising signal loss. No additional connectors or tools are required for the cable ends.

Black omnidirectional antenna for wall

The black antenna stands roughly two feet tall and is built for both indoor and outdoor environments. Its omnidirectional pattern radiates signal evenly in the horizontal plane, simplifying aiming during installation. Mounting hardware supports wall or pole attachment, letting installers position the antenna for best line-of-sight to handsets.

Questions about this item

Will the 20 m LMR400 coax cable need replacement after long outdoor exposure?

The cable is built for indoor and outdoor use; UV-resistant jackets on LMR400 typically last many years, so routine replacement is not expected under normal conditions.

What limits signal quality first when the antenna runs continuously in a DuraFon PRO system?

The 6 dBi omnidirectional gain sets the practical range ceiling; beyond that distance the signal drops off regardless of how long the unit operates.

Does the antenna or its 66 ft coax run hot or draw extra power during all-day operation?

The antenna is passive and draws no power; the coax carries only RF signal, so neither component generates heat or adds to the electricity bill.
