These days, anything with copper in it is expensive. If you doubt that, a walk into any Home Depot electrical department, where the wire is locked up tighter than Fort Knox, will prove otherwise. C…
So besides the fact that it’s too high of impedance, can’t carry enough voltage for broadcasting any signals, requires dedicated custom amplifiers, and costs more… Sure.
It only seems practical for certain receive antennas that already require an impedance matching transformer.
For most uses, RG-6 would be a better choice if you want cheap transmission line. It can easily handle 100 watts as long as you don’t use F connectors. For a single band antenna, the coax can be cut to a multiple of a half wavelength and there will be no impedance matching required if the antenna is 50Ω.

Do you have an alternate suggestion? I’ve got vhf/uhf in the attic, but only Ethernet in the walls to my desired destination from the coax demarc.
