Baluns
are used to connect balanced antennas to unbalanced transmission lines (coaxial
cable). They prevent antenna currents from flowing down the outside of the cable. They
should be located right at the antenna. They can also be used as "line
isolators" anywhere along the cable to prevent flow of induced RF.

1:1 Balun Kits |
| These balun kits are 1:1 current baluns. They consist of five large ferrite beads (total length 5-1/2 inches) that slip over the coax. Also included are three lengths of shrink tubing to enclose the balun and hold it in place on the cable. The baluns are for use from 3.5-60 MHz and allow use of RF power to the full capability of the cable. No tools are required for installation, just a source of heat to shrink the tubing. Heat gun, lighter, matches. |

4:1 and 9:1 Balun Kits |
|
Model BA-4-250: Is a 4:1 balun
kit used to translate a 50-ohm input up to 200 ohms at power levels up to
250 watts when used with a matched load. With a matched load, SWR will not
exceed 1.2 over the frequency range 1.8 to 30 MHz.
The kit consists of a F140-61 ferrite
toroidal core, two colors of #16 Teflon-insulated wire, a UHF connector with
hardware and an instruction manual. Model BA-4-250 | Cat. # E-101 | Price: $ 25.00 | |
|
Model BA-4-1500: Balun kit is
used to convert from coaxial cable to ladder line at full amateur radio
legal power (1500 watts) at 100% duty cycle. It gives a 4:1 impedance
step-up to reduce SWR on the coax. It also can be used between a
single-ended antenna tuner and ladder line and will handle high SWR in this
service. The kit consists
of two T200A-2 iron powder toroidal cores, two colors of #14
Teflon-insulated wire, a UHF connector with stainless steel hardware and an
instruction manual. Model BA-4-1500 | Cat. # E-102 | Price: $ 32.50 | |
|
Model BA-9-250: Model BA-9-250 is
a 9:1 balun kit used to translate a 50-ohm input up to 450 ohms at RF power
levels up to 250 watts when used with a matched load. With a matched load
SWR will not exceed 1:1 over the frequency range 1.8 to 30 MHz.
The kit consists of a F140-61 ferrite
toroidal core, three colors of #16 Teflon-insulated wire, a UHF connector
with stainless steel hardware and an instruction manual. Model BA-9-250 | Cat. # E-103 | Price: $ 32.50 | |
