Balun

The word 'Balun'

The word 'Balun' is formed from the words 'Balanced' and 'Unbalance' both been truncated and combined to form 'Balun'

Electrical Transmission Lines

Balanced Transmission Line

A balanced transmission line is when a signal is propagated between a pair of parallel wires. This type of transmission line will form a balanced circuit where signal forces will be both above and below the common ground.

Cables used to form a Balance Transmission Line are telephone cables, Cat5e, Cat6, Cat7, and infact any parallel cable pair could be used?

Note: is is prudent to only use cables that are specifically designed for the task in hand; also remembering the other important characteristics of interference suppression, impedance matching, frequency range and signal loss ( attenuation).

Unbalanced Transmission Line

An unbalanced transmission line  is when a signal is propagated between a pair of parallel wires; where one of the pair of wires is wrapped around the other wire to for a coaxial cable, in this type of circuit the signal forces will be all above or all below the common ground. This type of transmission line will form an Unbalanced Transmission Line.

Cables used to form an Unbalance Transmission Line are those specifically classed as coaxial, like those used in TV distribution; of types like CT100 or in CCTV; cable type RG59.

Note: is is prudent to only use cables that are specifically designed for the task in hand, also remembering the other important characteristics of interference suppression, impedance matching, frequency range and signal loss ( attenuation)

Connecting a Balance Transmission Line to an Unbalanced Transmission Line


Electrical transformers can be wound to form both Balanced and Unbalanced Circuits. 

A transformer can be designed to carry out the duty of conversion from say a Balanced circuit using one pair of Cat5e to an Unbalanced circuit using an RG59 coaxial cable,  this type of transformer is commonly known as a Balun Transformer.

Note: is is prudent to only use Balun Transformers that are specifically designed for the task in hand; also remembering the other important characteristics of interference suppression, impedance matching and frequency range.

Balun Transformer

A balun transformer is classed as a passive device and design permitting, signals will propagate in any direction across the transformer: for example a signal may travel form unbalanced coaxial cable to Balanced Cat5e cable or vice versa.

Note: Always select a balum transformer that has been specifically designed / selected for the capability to carry out the specific task.

I'm learning as I go. I'm intending to utilize it for simply periodic shooting at the range yet what truly made me need to get it is the new laws occurring here in California. It began off as only a fundamental form however the increasingly more I looked into online the more I needed Assignment writing service - AssignmentCamp to manufacture a rifle I can develop into not one I will develop out of in a couple of months. Having said that I like both the MBA-1 and MBA-3 however it appears the MBA-3 would simply be simpler generally thinking about my setup. The shooting I plan on doing will most likely be around the 400 yard mark.
