[TowerTalk] Can I solder parallel conductor transmission line at the spot where antenna wire is soldered to a balun’s connections and then simply disconnect the coax from the balun and use the parallel conductor to feed the antenna?

Can I solder parallel conductor transmission line at the spot where antenna wire is soldered to a balun’s connections and then simply disconnect the coax from the balun and use the parallel conductor to feed the antenna?

I have a 80-meter loop fed using a MFJ-918 balun to a quarter-wave section of 75-ohm coax and a run of 50-ohm coax, and I want to swap out the coax for parallel conductor transmission line.

The antenna wire is currently soldered to the pigtails of a MFJ-918 balun.

The parallel conductor needs to make a precarious run from the top of the trees the feed point is in, past a parallel exterior wall, and past a few trees to get to the shack. I’m not sure if the wall and trees will compromise the performance of the parallel transmission line to make it worthwhile to swap the coax out for it.

If I can leave the balun’s pigtails soldered to the antenna wire, disconnect the coax from the balun, and solder the parallel conductor line to the spot where the balun’s pigtail wires are soldered to the antenna wire I’d like to see if I can get past the wall and trees that are in the way. 

I’ll disconnect the balun if I can get the parallel transmission line past the obstacles and to function better than the coax.

I’d like to avoid unsoldering or cutting the balun away from the existing connection to the antenna wire because it’s a lot of work in a precarious location.

Can I solder the parallel conductor transmission line at the spot where the antenna wire is soldered to a balun’s connections and then simply disconnect the coax from the balun and use the parallel conductor?

Thank you,
