Andy, one thing to keep in mind is that depending on what band/wavelength you are feeding the antenna your 4:1 balun may or may not be optimal. The balun...
I believe that it is considered common practice to use a 1:1 balun in situations where the antenna impedance is unknown (as would be the case when using a...
Thanks to all for the feedback. The 1:1 versus 4:1 balun is an issue I did much head scratching over, and much reading. I contacted the folks at Balun ...

.....If you run your ladder line all the way to the tuner [a MFJ 989B for instance] is the balun still necessary? For me the balun thing is very confusing. 73 ...
You want the lader line to be balanced, that's why you want the balun. It is good practise to calculate or measure the impedance at the point you insert the...
... A lot of MFJ tuners - I don't know about your specific one - have a balun built in. If it has two binding posts on the back for a balanced antenna, then...
From my ex .. As only about 1/3 of the ae leg length radiates , the ends are not too important , but, keep then 6 ft or more above the ground, lower...
Hey, The APRSISCE/32 program you have made looks very capiable. I see that it is able to work with a kiss mode tnc, this is interesting to me because recently...
