Ham Question: Coax Loss and Remote Tuner for 43 Foot Antenna

A reader asks…

I am thinking about getting a 43′ vertical to use on 160 to 10 meters.

Has anyone calculated the coax loss for 100 feet of RG-213 coax, especially on 80 and 160 meters?

Would it be beneficial to build a remote tuner [like below] and place it at the base of the 43′ antenna to reduce coax loss?
