outstanding performance

A collinear omnidirectional antenna that utilizes a center-fed collinear dipole array that provides performance superior to traditional bottom-fed collinear designs.
 A center feed collinear has a radiating element that more evenly feeds a signal of the appropriate amplitude and phase.
 In a bottom-fed design, the signal reaching the upper element already experiences significant amplitude and phase degradation. 
In most cases, the upper elements of the end-fed design contribute little to the final composite gain and pattern of the antenna. 
In the MHZ-TD-2700-01, internal copper hard wires provide a low loss path for the central splitting and phasing components of the antenna. 
The brass radiating element of the MHZ-TD-2700-01 utilizes an air dielectric for lowest losses and excellent radiation efficiency. The design is factory tuned for superior performance.
Rugged and weatherproof Ceiling antennas, also known as ceiling antennas, are mostly used in public places such as shopping malls, parking lots or basements.
