Hi all, particularly Walter (since he mentioned it): I've been bedeviled by a question with multiple possible answers.
I'm a fan of the idea of using a field antenna as Walter describes by using a BNC - to binding post connector directly to the radio. I'm leery of that because it flies in the face of what I've been told about these antennas: I'm assuming the radio BNC connection is unbalanced and the wires form a balanced antenna, more or less. I've seen deployments with end-fed 9:1 baluns and without, even documented on YouTube with great successes. I can tell you that the 9:1 balun setup doesn't seem to be working for my current field deployment but I'd sure like to understand why a balun isn't recommended in this setup. I'd love to just take the wire and put it on my WonderPole and go for it, but I'd like the understanding first. Why does this work? :) Thanks.
