AO1903 
Omnidirectional Antennas

AO1903This center-fed design antenna ensure consistent gain and impedance over the entire frequency band of 1710-1880 MHz. The radiating elements are made of copper and enclosed in a weatherproof, low-loss, fiberglass housing. 
The base of the antenna is a die-cast
aluminum support. The antenna base permits the antenna to be top-mounted with the cable inside the support pipe. Alternately, the antenna can be side mounted with the cable running along the outside of the support pipe.
Each antenna can also be mounted
inverted using the supplied hardware screws (read instructions before mounting).

• Heavy-duty lightning protection and DC ground
Protects against damage from lightning.

• Center-fed design
Eliminates beamswing across the band.

• Small diameter construction
Reduced wind loading.

• Broadband design
One antenna covers entire band.

• Versatile base mount
Permits various mounting capabilities.
