Noone has the right to make fun of anyone asking a question about call/s and how they are used. Your question is a good one, as the length of a tube call is often the subject of discussion. Does it effect the sound according to the length, not as much as you think, what it does do, is create a directional effect, I have seen some callers in contests take a short hollow tube and place it infront of their tube call when they are running it to simulate the turkey as if it was changing the direction of its head looking for the hen. I have made several different lengths, any where from 2-1/4" to 4=1/2" in length. With the longer lengths having a bell on the end, something to hold onto, if you have a tube that you feel is too short, or can't hold properly, get with the call maker and I bet they will make one that will fit your needs.
