EZNEC ROHN25 model:

128' resonant at 1.796 MHz, 35 +j0 ohms
115' resonant at 2.000 MHz, 35 +j0 ohms

115', 1.800 MHz, 25 -j46 ohms
115' 1.800 MHz, 4.1 uH base series inductor, 25 +j0 ohms

Assuming what value of ground loss resistance?

Radiation resistance of 35 ohms plus several ohms of ground loss resistance is pretty close to what you want, without matching.
