I use 50Ω coax all the time for receiving and even 50Ω aerials.

....Your transformer is likely to attenuate, so I wouldn't even bother.

It doesn't really matter for receiving, just use 50 Ohm coax and you get the benefit of being able to do a cheeky TX if you accidentally go to the effort of plugging in a load of TX gear and turning it on. You'll likely get more loss from the transformer than you will from the mismatch for receiving.
