I got a question for the IDF experts. I have looked all over the internet and in several books I have but haven't found a answer as to how long the antenna is on the M51 shermans. Also on the M51 antenna did they ever fly the Israeli Flag or a pennant on it if so what colors were on a pennant?

This is kind of late, but as to the length: The Tamiya M51 kit has brackets on the top of the turret bustle for spare antenna rods. I'm using this length for mine.
