Well, you need to convey 105/48=2.187 amps. 24 gauge is 2.5 ohms per 100 feet. If you used 4 wires for one polarity and 4 wires for the other polarity, you would have .625 ohms per polarity or 1.25 ohms per loop/100 ft.
So 1.25 * 1.2 = 1.5 ohms for the 120 foot loop. 1.5 * 2.187 = 3.28 volt drop. And since you will really be running it of of 54 volts if a battery is involved, you have even less current and more voltage overhead. If the equipment will run at 44 volts you are golden. I think you are golden. Yes, it is pretty sure to work. If not, use all the conductors on one cable for one polarity and all the conductors of the other cable for the other polarity.

It appears this link will have 4 LC connectors on single fiber. Theres a conduit kit for the radio, looks like 2 to each radio in 2+0 if im understanding correctly. I figure we will need an enclosure at the top for these to enter to let the fiber pairs split out. The two big questions are Can I get this cable in pre terminated patch cords affordably and just cut the jacket back to get the pairs to the radios. If its preterminated without running big pipe, conduit is kind of out so is just something copper clad similar to BBDGE recommended? Neither of these are more than 120 feet Our guy can splice at 70 bucks per, but im not sure how viable that is in the air (these are grain elevators though) Both these radios have existing cat5 BBDGE, can I use that to run about 105 watts @ 48volts split out to two radios at 120 feet? Im pretty excited to not have ethernet negotiation issues or surges
