Two yagi antennas in parallel...

What impedance transmission line should be used for two 50 ohm yagi antennas connected in parallel on top of a mast, for a 25 ohm impedance transmitter ?

do you have 25 Ohm impedance coax?

Seems your answer is a 25 ohm transmission line ?
Yes, two equal lenght RG58 in parallel.
The antennas paralleled, aiming 180 degrees from each other, at a fairly straight river shore to serve communications upriver and down river.
