Scott,
let's compare the radiation resistance of the three antennas at 1.8 MHz.
55' x 82' Inverted-L is 16 ohms
100' x 36' Inverted-L with the 36' wire sloping downward at 45 deg is 28
ohms
100' base-loaded vertical with 22 uH inductor is 18 ohms
The antenna with the highest radiation resistance will be more efficient and
exhibit greater VSWR bandwidth.
