## **Antenna Assembly** 

This antenna is designed to be assembled over a vertical support in 90◦ vertical position. 

Follow below indications for optimal performance of your antenna setup. 

- 1) Install on a clear location with 360 degrees open area, otherwise coverage is lower and signals may be significantly distorted, providing very poor coverage. 

- A Vi av; : ’ ’ ‘ ‘. ‘. 

- ‘= 

- eases 2c es 

- Avoid out-of-phase Install in a clear location self interference by with clear signal path in reflected signal and all directions obstructed path 

- 2) If the antenna is installed on a location with metallic objects nearby, make sure the antenna is always above such objects and as far as possible. Metallic objects and surfaces negatively impact in antenna VSWR and signal reflections.

- 3) Provide solid mast assembly using included antenna support 

For correct mast/pole assembly, the metallic support must fully contact the metallic antenna support sleeve, not the fiber glass body. 

Follow image examples for correct assembly.

Cc Poor quality RF cables not only reduce signal levels but also distort signals due to out of phase VSWR imbalance.
