4:1 UNUN

Description

The
4:1 UNUN
is design to balance 200Ω ohm line to match a 50Ω ohm. The resonance is nearly flat throughout the entire HF ham amateur bans 1-30MHz
This particular UNUN  is use for the most part on Vertical antennas, wire antennas perfect for 43 and 33 foot vertical antennas, the operator will need an external antenna tuner and posible a 1:1 balun to eliminate common mode.
This UNUN is a 4:1 ratio, balanced 200 Ω-ohm load to unbalance 50 Ω-ohm
Ferrite 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:1-30MHz
Hardware: stainless steel hardware.
Junction box: marine grade, suitable for outdoor installation. 4x4x2
High efficiency: (98%99%)
BALUN or UNUN doesn’t help to lower the SWR. UNUN is the same "Un"balance to "Un"balance load.
The UNUN or Balun it might not be the one on the picture depending on inventory. However, it will be design with the specification that is described.
