GNX375 Transponder antenna

I have a delta pop aviation transponder antenna and I am wondering if it will work with my GNX375. The GNX375 installation manual says that some transponder antennas only work at 1030 and 1090 Mhz. The Delta Pop website confirms that their antenna meets this specification.

Garmin seems to also want a UHF element that works at 978 Mhz with VSWR <1.7. Delta Pop does not say if their antenna meets this specification. Does anyone know how to get hold of someone from Delta Pop Aviation? I tried to look on the Delta Pop website, but the contact via email button does not seem to work. I can't find any other contact information.

Would like to avoid buying another antenna if possible.

Thanks,

Bryan
 
My website needs updating and I'm not a website guy,:confused: the antenna you have will perform well on both 978 and 1090 MHz.
The antenna spec’s are well within the requirements of Garmin and the like.

Works great on both freqs

Using on uAvionix echo --- both freqs work well on the receive side -- TX on 978.
