APPLICATIONS
- Complies to ETSI EN 301 525 V1.1.1 (2000-03)TS3
- IEEE 802.11a wireless LAN system, Wimax and wifi system compatible
- Amongst others, can be used with Lucent, Proxim, Buffalo, Breezecom, Alverion, Cisco, D-Link, Intel, Linksys, Samsung, Symbol and Avaya.
- Used in conjunction with wireless access point / client
- Used for point to point links, point to multi point links, ISM, WLAN, data/telephony and CCTV
FEATURES
- These professional Antennas are outdoor weather sealed and individually tested gas-tight
- Welded steel gives maximum strength/weight ratio
- Lowest windage, and highest survival rate, in independent wind tunnel tests
- These antennas can be tilted (standard pole mount brackets with optional tilt brackets)
- Material-welded wire hot dip galvanised - no rust
- Nesting, and fully stackable on the flat in the warehouse. Most compact for shipping.
- Dimensions of wire-14G in mesh 12.5mm X 25mm
- Method-press formed from flat panels for uniformity
- Brackets are made from galvanised steel.
- Dipole boxes are made from ABS shock resistant plastic for maximum durability.
