Topband: INVERTD L Reactance

My inverted L is about 65 to 70 Foot Vertical, with the rest horizantal.  I have attached the Ground Braid of my coax to an aluminum Plate about 2.5 feet in Diameter that has 66 holes drilled on the outside of the circumference.  From their I have run 66 #14 THHN ground Radials out in a symetrical pattern for about 70 feet.  The vertical Part is not in contact with any trees or vegitation until it changes direction for the horizantal run.  My SWR is 1:3 to 1 when fed with 50 OHM coax, and when I use an antenna analyser it reads about 55 OHMS.

My question is this,  does an inverted L have a higher reactance value than the typical 36-39 OHMS that a vertical has?  Or must I continue to Add readial to the Ground.  I can still put down more of the 70 footers but I can also put down about 20 that are 1/4 Wave length long.  I hear well but for some reason no one hears me.  This is with 1.5KW to the Antenna.  Any help would be appreciated before the snow Flies.
