This four element Lightning Bolt Quad covers 20, 17, 15, 12 and 10 meters. It
is fed by a common balum. (one input PL259 and 5 output pairs of conductors)
Does anyone know what type of balum this is and what would be the replacement
I imagine the driven elements for each band has an impedance of about 80 to 100
ohms. The feed into the balum is 50 ohms.
If a person provides a 2:1 balum for each feed, would the unused balums be
terminated in 50 ohms or left open?
Any more thoughts on this antenna?
