VsTank Pro, along with Marui, uses the same antennas (structurally). However for Hen Long, you can see that they do not have a uniform setup for antennas. In the M1A2 Abrams, they mimic the VsTank Pro and Marui antennas but the antenna doesn't have a hook. Instead, they use the spring-like part of the antenna as a socket to insert onto the tank. While this does not really affect how the tank looks, this means that VsTank Pro/Marui antennas do not work on the Hen Long M1A2 Abrams.

Unlike the M1A2 Abrams, Hen Long chooses to use an antenna that comes out from the rear of their Leopard2 A5 tank. This antenna is what differentiates Hen Long with VsTank Pro and Marui. The antenna is not removeable.
