Currents do not flow equally in both feedline connections, … WebWe often get the question – Do I need a balun or an unun? The proper question is – do I need a feed line choke or an impedance transformer whose output is configured as balanced (balun) or as unbalanced (unun)? A feed line choke is a 1:1 impedance transformer with equal input and output impedance (usually 50 or 75 ohms in/out). cell phone call history records
