4:1 Balun Current or Voltage

Description

This balun is a 4:1 ratio, balanced 200 Ω-ohm load to unbalance 50 Ω-ohmFerrite Core:Low permeability ferrite Coated and sealed for a longtime durability.Wire:14-gauge heavy duty build Polyamide-imide, magnetic wire. Power rating:5000 watts—2500 watts—1000 watts 1-30MHz. To obtain full power handling you must have 1.5 lower SWR if is higher than 1.5 SWR will reduce power handling and created loses. Frequency range:1-30MHzLoss:less than 0.2 Hardware: stainless steel hardware.Junction box marine grade, suitable for outdoor installation. 4x4x2 High efficiency(98%99%)4:1 Guanella current balun. Is the best choice for an impedance transformation than the voltage type balun since the shifting electric field and permeable core of a voltage balun causes the lagging of the magnetization of a ferromagnetic material which will create loos (heat)     · This is an exceptional ferrite mix coated with excellent design to minimize excessive stress·     The wire size selection and Teflon-insulated wire sleeves provide the perfect impedance matching and excellent insulation, unlikely the common Thermalize wire, that you see with other makers.·     This balun is a 4:1 ratio, balanced 200 Ω-ohm load to unbalance 50 Ω-ohm. ·     The 4:1 balun transformer is well known for holding low attenuation. 
4:   1 Voltage Balun is use for antennas for the Window Antenna The Carolina Version, Folded Dipole, etc.        
 I    highly recommend to install a 1:1 balun to eliminate RF into your shack if you are experiencing any.     A balun doesn’t help to lower the SWR. A balun is a device that is being used to transform a “BAL” balance line to “UN” unbalance load, to your radio, that’s how the worth BALUN was created.   UNUN is the same "Un"balance to "Un"balance load.
