"Hmmm... I would have assumed it was a phased array conformal antenna" - Astramike
You are correct Sir, and I am wrong. There is a non steerable low gain antenna on the roof of the T7 but there is also a phased array high gain antenna.
The phased array antenna is an
Esterline CMC Electronics Inc (Canada) model
CMA-2102SB (source airframer.com)
It is 60" long, 18" wide and 4.5" high, takes 69 watts, can switch the beam in 50 microseconds and offers a minimum of 9dBiC gain over 100% of the hemisphere above the horizon. Looking straight up it gives 17dBiC gain.
dBiC is decibels of gain of the antenna relative to an isotropic antenna (no gain) dealing with a circularly polarized EM field.
The gains offered by this antenna range from 2 to 7 relative to an omnidirectional antenna.
