Topband: fcp question

[james soto]

Hello friends
i been looking closely at the FCP antenna system. actually a iam using an inverted L
antenna,about 126 ft after tuned to 1.4 swr. the vertical portion of the antenna is about 45ft
and the other portion in horizontal position. the feet point is at the botton of the vertical portion
just about 1 ft of the ground. my question is if i install the fcp system at 8 feet hight that will cut about 7 ft
of the vertical portion,could i make the installation of the fcp shorter than the 8 feet ? or the inverted le will work ok with
just 37 feet vertical section? 
thanks KP2BH/KP2DX
