User Reviews for HF Beam Antenna Calculator

Simple and helpful

Runs fast for beam calculations Great for the ham radio enthusiast

Missing one part

I'm only giving this app three stars because its is leaving out how to drive the driven element! Yeah, that's kind of important to make a beam work. Maybe include one drawing of how to connect the coax to the driver and this app would be golden. I'm sure it's insulated from the boom, are we to connect the center of the coax to the center of the driver?
