When installing a mobile signal repeater ,the more omni ceiling antenna the larger coverage ?

Yes, generally,the more omni ceiling antennas you use in a mobile signal repeater setup,the larger the coverage area you can achieve . 

Here is why : 

Increased signal distribution : each antenna acts as a point source for radiating the amplified signal .more antennas meas more points of distribution .leading to better coverage in different areas . 

Reduced dead zones :by having multiple antennas ,you can minimize the chances of signal dead spots or weak areas within your coverage zone . 

Improved signal strength : multiple antennas can help to reinforce the signal in areas where it might be weak ,resulting in a more consistent and reliable connection . 

However ,there are some factors to consider :

Antenna placement : the placement of the antennas is crucial ,they should be strategically positioned to maximize coverage and minimize interference . 

Repeater power : the power of the repeater itself is also important . a more powerful repeater can support a larger number of antennas and provide a stronger signal . 

Building layout and materials :the physical structure of the building can affect signal propagation . walls ,floors ,and other obstacles can attenuate the signal . 

In conclusion ,while adding more omni ceiling antennas can generally improve coverage ,it is essential to consider the overall system design and the specific requirements of your environment to achieve the best results . consulting with a professional installer can help you determine the optimal number and placement of antennas for your mobile signal repeater setup ..
