Antenna Considerations
Note – Please use care when removing the radio antenna. The SNR900 
antenna contact tip is designed for maximum efficiency and very low 
loss. To maintain its integrity, do not remove the top cap from the 
radio housing.
Make sure that you mount the base and repeater radios as high as 
possible. An increase in the antenna height increases your line of sight 
and is the most effective way to increase the radio’s range. 
Figure 4.12 shows the optional infrastructure antenna mounting for 
the SNR900.
