But if we using the same size blumlein line as pfl, we can only get a square pulse with 31ns pulse duration. this experiment results show that replacing the intermediate conductor of blumlein line by helical conductor can get long pulse
實驗表明採用螺旋blumlein型脈沖形成線我們得到負載上的方波脈沖的脈寬為260ns ，而同樣長的blumlein線在負載上只能得到31ns的方波。也就是說螺旋blumlein線在原理上是可得到長脈沖的。
