Ran a basic EZNEC model with no tower present for your 80 ft X 45 ft inverted L at 1.825 Mhz. The base impedance for this is 28.5 - j 130 ohms.  The get rid of the reactance I extended the top wire an additional 20 ft so 80 X 65 ft and base impedance is 37.2 + j0. The tower is definitely influencing the inverted L.
