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.

That's a GREAT calculator Frank. Thanks again!

This is an alternative calculator:
www.qsl.net/co8tw/Coax_Calculator.htm
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 .

Does anyone know how much power would be lost if a resonant antenna with an
Impedance of say, e.g. 36 Ohms is fed with 50 Ohm coax? Is there a good source
where I could look up this kind of information?
Thanks!
