I've just replaced my old cable with some nice shiney new 50ohm coax

little extra out of my antenna, I want to add a balun but I am confused with
this transformer ratio stuff. I realise that a long wire has quite a high
impedance. However, should I go for a 1:4 or a 1:10 ratio balun. If I went
for the 1:10 would it be overkill and will it make any difference over the
RF if I only had a 1:4. I ask because I can get a 1:10 a lot cheaper than a
1:4.

Confused? I am

You may wish to try an ICE matching transformer, they are reasonably
priced and are built well. Another advantage is that you can play
around with the transformation ratio from 6:1, 9:1, 12:1 and 16:1.

I would suggest the DC isolation version and you might as well get the
one that goes to 100kHz in case you want to pursue beacons - that
would be model 182A.
