Challenger ll antennas

Putting the finishing touches on Dragon’s 1/72 Telic Challenger so does anyone have an idea what length the three antennas located on top of the turret should be?

Hey where are you guys hiding? I know a few of you have built the Challenger. Even if you give the height in inches of a 1/35 model it would be of help. Thanks.

About 2 1/2 inches in 1/35 (around 8’ on actual vehicle).
