Hi Bob,
As Wes points out, the AC6LA calculator is overly simplified and not
very accurate. Despite that, the answer to your question remains the same:
The additional loss caused by a 50 ohm coaxial cable feeding a 36
ohm load is insignificant at 1.8 MHz.

This is an alternative calculator:

For 200 feet of RG-213 terminated in a 36 ohm load,
the additional cable loss at 1.8 MHz is only 0.026 dB .
