For me, it's not the wire that is a problem. It's rain..
When dry, most all the 300 ohm lines are going to
be fairly low loss. Even with the cheap wire.
But get the line good and wet, and it all goes out the
window. For this reason, I would prefer a windowed
ladder type line for this, rather than 300 ohm.
It's less effected by rain.
Most ladder type lines will be in the 450 ohm range,
but that would vary with spacing of the conductors.
But that is not critical in your case.. 300, 450, 600
ohms, doesn't really matter too much..
