Hi All, I have a Create Log periodic antenna 50-1300mhz.I am having a hard time with FM overload(VHFair) even with a FMTrap filter(Par Filter).My question is can i remove 4 of the longer elements from the back of the antenna to cut back the performance of the antenna to maybe 100mhz to 1300mhz?The other Create antenna only has 17 elements where mine has 21 elements.Any help would be appreciated. Thanx, Jack
