(LI-2) RF Line isolator
[LI-2]

HF Choke, RF isolator, Current Balun


This is made of 10 ferrite core with high permeability EMI which is done to stop, reduce or eliminate unwanted RF from being conducted back into the coax, This isolator will only remove or "choke" unwanted RF power present on the coaxial feed-line and not affect the RF power you want to deliver to the antenna. Made of RG-142 , 50 ohms, rated at 3500 watt @ 50 MHz, this double silver coated copper braid shield at 95% can be used with any linear amplifier, without attenuation at this length. Center wire made of AWG19 solid silver coated.

Can be use between transceiver and amplifier or directly under the center of dipole. Only 19 inch long, waterproof and enclosed in CPVC tube to protect ferrite to be broken, made to be inserted in new or existing antenna with SO-239 ( Fem ) silver plated connector and PL-259 (male). Have been used in commercial field problem, will stop the fire detector, wireless phone and any electronic device to turn on with RF radiation.

Take note , only the current choke in this sale, center insulator show as example only.

 

 

 

 

  • Elimination of radiation from the feeder cable
  • Makes the antenna radiation pattern predictable.
  • Dramatically reduces QRM, TVI to neighbors.
  • Helps to keep RF out of the shack
