FAQ:
Q: What do you need to know about a balun?
A: A balun is any three port device with a matched input and differential outputs. It is most succinctly described by the required (ideal) S-parameters: S 12 = – S 13 = S 21 = – S 31 S 11 = -∞ Note what is implied by this: • A balun is a three port power splitter, similar to a Wilkinson or resistive power divider.
Q: What are the names of the 1 : 1 balun TLT?
A: 1. The primary reason for this work is to explain how a particular Transmission-Line-Transformer (TLT) known as a 1:1 Guanella-balun operates. Three other commonly used names to describe this balun are: “current-balun”, “isolation-balun”, and “choke-balun”; I’d suggest committing all four names to memory.
Q: What does one balun 800 watt antenna mean?
A: BalUn means: Balanced to Unbalanced. This enables us to adapt an unbalanced fed system (coaxial cable) to a balanced antenna system (dipole antenna). The 1:1 BalUn 800 Watt is suitable for QRO.
Q: How long does it take to Assembly a balun kit?
A: Balun assembly time takes about an hour and is a fun learning process. Model BA-1-1500 is a 1:1 balun kit used to translate a 50 ohm unbalanced input to 50 ohms unbalanced at power levels up to 1500 watts PEP when used with a matched load.
