Yes, but there are buts..
I am no radio expert, but did some experimental work with UHF antenna 35 years ago at Tec colledge. The reality is we need a 360 degree globe around our aircraft, which will be difficult to achieve, esp with only one antenna.
Assuming no blanking by aircraft structure. A vertical dipole would be the best option, at the expense of blind spots above and below us.
A whip antenna is in fact half a dipole, and requires a ground plane to make up the other half. There is a high risk that the antenna is not matched to the feed, and will in simple turns sap power from the signal, and possibly cause the TX section to overheat. Both can reduce range.
Ground planes will shape the signal. A horizontal flat plate will deflect the horizontal donut upwards, making you invisible to any RX below the plate. Using arms at 45degrees down improves that, but is still less than ideal.
A dipole in as clear air as possible or two whips, one above and one inverted below the aircraft would give the best coverage. Neither solution would be 'mobile'.
Sorry got to go to work now
