Improving my antenna

Hello all, i need some advice / help

My boss gave me an antenna that is no longer being used.
Type: A-OMNI-0069-V3. I know this is made for the GSM bands.

Would it be posible to cut someting from the pcb to make this antenna work at 1090 mhz ADS-B.
Below some pictures, the dipole’s are 139 mm

If you don’t know, it’s very likely best to just build one of the DIY self antennas (Three Easy DIY Antennas for Beginners)

Or just buy an antenna:

Or the FA antenna.

Or check here for a cheap ebay PCB antenna: https://github.com/wiedehopf/adsb-wiki/wiki/Useful-items-for-purchase

It’s tuned for GSM band, so what are you gonna do?
If you wanted to modify it, you would need an antenna analyzer.
