The above is a link to the antennae datasheet. I have the OS-GSMQB-00-C which is a very stubby one. I have two identical - one on each output. They are SMA i.e. not reverse.
I'm thinking I need the penta band one (IR-GSMPB-02-C) for the higher frequency output now that I know I need to go to 2100MHz. What sort of improvement can I expect with swapping out the antenna? Will it be very noticeable? Will I get 3dBm?
The thing is I screw the analyser on to the SMA connector in place of the antenna and get 20dBm from the low range VCO and 10dBM from the high range. I guess that is degraded more with the wrong antenna? Anything to boost this band would be helpful. I reckon from 1800-2200MHz
