BA-2-100VHF

100:50 ohm (2:1) VHF Balun or Unun Core Kit, 3-150 MHz, 100 watts Preassembled BA-2-100VHF

Model BA-2-100VHF is a 2:1 balun/unun kit used to translate a 50 ohm input to 112.5 ohms at RF power levels up to 100 watts PEP from 3-150 MHz when used with a matched load.Excellent for log periodic antennas or resonant loops with feed point impedance from 100-120ohms.

The kit comes pre-assembled (already wound but without I/O connectors so you can add your favorite input and output connections and enclosure box.

With a matched 100 ohm load the SWR over the frequency range 3 to 150 MHz is shown in the following table measured with an AIM 4170 network analyzer. Notice that the conversion from 100 to 50 ohms is very consistent from 3-160 MHz and SWR is less than 2:1 over the range allowing easy tuning by most radio internal antenna tuners or an external tuner. Graph is for a 2:1 balun often used with delta loop, quad or horizontal loop antennas. Kits fit into 4″ x 4″ x 2″ box (Part# CB-Box-1).
