UR77Meteorit

Hello, New in this neighborhood. I am currently working on a Meng Merk 3D LIC Late and looking at some pictures online (whenever I can find some of this specific Merk variant, which means if you have some good online resources for the Merks operating during Operation Protective Edge in 2014 I could use some), I can see different antennas setup on the back of the turret. Some regular flex antenna bases, some sort of antenna mast, some mixed up.... Is there some kind of SOP within the IDF when it comes to antennas? Does it depend on the role of the tank within a platoon? Does it depend on the period of time? Thank you! Thomas
