Hello,

Forget reading books! Look at the aerial being used and the feeder
connecting it to your radio. Calculate the difference in impedance. Simple
as that.

So in as much as I realise the importance of using a balun when feeding
certain antennas, what factors determine what ratio is best suited to the
application? Is there a general rule?
(That is to say a long-wire is best fed with 'x:1' where a loop antenna is
fed with 'y:1'?)
I typically connect a center fed dipole is with a 1:1, but what
configuration calls for the 4:1, or even the 9:1 ??


(reply here please, it'll probably make an informative reading for most)

Thanks,
Pat
