You are doing great!


A 1/1 current balun will work fine although not a perfect match to the feed line because a 1/2 wave dipole is NOT 50 ohms.


When you check SWR, you are checking the "match" of the FEEDLINE at the FEED POINT.  You should check SWR AT THE FEEDPOINT, but that is not always possible.  So, we check SWR at the other end of the coax.  Here is the thing though, unless that piece of coax is exactly a multiple of an electrical 1/2 wave length at the specific frequency you are testing, then the reading at the feedpoint vs the reading at the meter, will be different.  Why you ask?  Because that piece of coax acts as a transformer and actually transforms the reading.


See, you learned something new today!
