If you have a decent CMC choke & 1:1 balun on the ground at the tuner / radio you could use the shield of the coax as the bottom half of the dipole, and just use some light gauge wire for the top half
~58' of wire & ~58' of coax will provide a vertical center-fed 80m dipole and the shield of the bottom half will radiate down to the CMC choke & 1:1 balun, necessary to keep RF out of the rig & mic.
Best to use a well shielded, metal mic and a real good ground rod system!
I hope that rig has a processor / compressor since those heil ICM mics are typically not a good DX / Contesting mic due to having a more muffled sound. With the processor it should be fine. If you can get hold of a Turner +3 CB desk mic and add a .01µƒd in series with the internal preamp output you'll get rave audio reports. I even added a VR to adjust how much I want to bypass the bass filter capacitor which acts as a tone control.
Why not a 120' center-fed coaxial vertical dipole for 80m!?!

Nasty noise on receive.
