I don’t think I will fully understand anntennas. A friend gave me a J-Pole for 2 meter ham band, does very well only 1.2 SWR on, it. for fun I tried to do a 70cm transmition on it. I figured I would do it for less then a second thinking that the SWR would be ultra high (mind you the main element is about a meter and a half long and the reflecting element is about 50 centimeters long) well I had an inline SWR meter installed, the nedle that is use to show the SWR did not move much, not even hitting 1.1 to 1 on 70cm.
