The MFJ-918 1:1 Current Balun
is made up of 50 hi-permeability ferrite beads on high-quality RG-303 teflon coax in heavy duty weather protected PVC housing. Handles 1.5 kW, 1.8 - 30 MHz. Very suitable for wire dipoles.
|Balun|| : ||1:1 , Current type|
|Frequency|| : ||1,8-30 MHz|
|Socket|| : ||SO 239|
|Max. Power|| : ||1,5 kW PEP|
|Dimensions|| : ||H 127 x B 50 mm|
Please note! The specified max. transmit power applies to a SWR of 1:1 measured directly at the antenna feedpoint. If the maximum permissible transmission power is exceeded for a long time, the ferrite material becomes saturated and the balun will be damaged.
Do not use the current balun when the SWR measured at the antenna is over 3:1. In case of high SWR, high RF voltages occur at the feedpoint and the power output must be reduced to prevent balun breakdown.
