The vehicle cannot have a high mounted omni, it must be vandal proof and also must be a quad band antenna to work on Telecoms 2100mhz. The antenna also must be pointed down from an L bracket therefore creating some shadowing....
The reason for 2100mhz is the use of this freq for high use sites etc and the consultant wants it like this.
The challenge we have is we can provide a shark fin or small stubbie 850 antenna perfect for the vehicle and obviously XT but because we have been told that it must do 2100mhz the options available to us are limited.
Yes we can buy quad band antennas that could be used however my issue is purely that the antenna is not going to be mounted in a normal sense (pointing down in vertical arrangement) the gain at 2100mhz is low and as the antenna is receiving 850mhz it may pick up a stronger signal on 850mhz on another cell and use that instead. The shadowing also will limit performance.
Have done plenty of bus and mobile setup's like this but usually 2100mhz is a Vodafone issue for us but in Auckland it may be used a lot more on Telecom.
I know what I would normally provide, my suppliers agree but do need some advice from potentially those with understanding on Telecoms 2100mhz network and how much of a benefit it will be over 850mhz especially with buildings making great big signal walls..
Thanks in advance
