Product information
Reliable dual-band performance for indoors and outdoors
Are you looking for a powerful and compact WiFi antenna that will perform for a long time in striking and challenging locations? The 20-0004COBW-NF is a high-quality rod antenna that is specially designed to achieve a stable wireless connection. Thanks to the support for both 2.4 GHz (5 dBi gain) and 5 GHz (7 dBi gain), you get the most out of modern dual-band network equipment. The antenna radiates in a circle of $360^\circ$all around (omni-directional), ensuring even coverage around the mounting point.
Indestructible fiberglass housing
The antenna is made of high-quality white fiberglass. This material optimally protects the internal antenna system against the harshest weather influences, UV radiation and temperature fluctuations between -40 ºC and +80 ºC. This not only ensures that the antenna continues to function perfectly technically, but also maintains a neat, professional appearance for years to come. This makes the model extremely suitable as a marine antenna on ships, or on the outside walls of business premises and warehouses.
Smart mounting options and cable freedom
There is a standard N-Female connection in the metal base of the antenna. This means you are not tied to an integrated cable, but you can choose exactly the coaxial cable with the length and connectors that your installation requires. The supplied spacer (bracket) ensures sufficient distance to the wall for unobstructed signal radiation. Do you want to place the antenna directly on top of a switch box or housing? Then you can easily mount the antenna without a bracket via the lead-through with the supplied lock nut.
Note: This model is the direct successor to the 20-0017COBW-NF. If you mounted the old version in a mast, we recommend combining this antenna with the optional mast bracket 20-DDSBC-NF.
