BL 10-160-5KW

Model: BL 10-160-5KW
High Power HF Balun
$45.95



This is a 1:1 current / choke balun with an SO 239 connector for coupling your coax.

These are very efficient baluns and use low permeability, less lossy ferrite than most other baluns on the market today. Less losses means less heat on the ferrite material, less chance for balun failure and more power delivered to the antenna.

The power handling capability of this balun is phenomenal. It is conservatively rated at 10 KW on 160 meters and 5 KW from 80 to 10 meters. These ratings are good for up to 2 to 1 SWR.

The MIL SPEC transmission line used to make the balun uses: silver clad copper center conductor, silver covered shield, solid Teflon dielectric with a voltage rating of 1900 rms volts and temperature range of -55 to + 200 degrees centigrade.

The balun is enclosed in UV rated material. The hardware is stainless steel so NO RUST! There are also two drain holes in the bottom of the enclosure should any water migrate its way inside the enclosure.

High Power HF Balun
$65.95



This is a 1:1 Guanella current / choke balun with an SO 239 connector for coupling your coax.

The GU 6-160-5KW balun is a very efficient balun. It is rated 98% efficient or better on all HF bands. The balun is superior to the beaded baluns that use higher permeability ferrite.

The power handling capability of this balun is phenomenal. It is conservatively rated at 10 KW on 160 meters, 5 KW from 80 to 10 meters and 3.5 KW on 6 meters. These ratings are good for up to 2 to 1 SWR.

The MIL SPEC transmission line used to make the balun uses: silver clad copper center conductor, silver covered shield, solid Teflon dielectric with a voltage rating of 1900 rms volts and temperature range of -55 to +200 degrees centigrade.

The balun is enclosed in a UV nema rated enclosure. The hardware is stainless steel so NO RUST! There are also two drain holes in the bottom of the enclosure should any water migrate its way inside the enclosure.



GULI 6-160-5KW

Model: GULI 6-160-5KW
High Power HF Line Isolator
$65.95



The 50 ohm line isolator has two SO 239 connectors for direct coaxial cable hookup.

The GULI 6-160-5KW line isolator is used to isolate any RF (common mode) that may have worked its way back to your station. It uses the 1:1 Guanella current / choke design.

The power handling capability of the line isolator is phenomenal. It is conservatively rated at 10 KW on 160 meters, 5 KW from 80 to 10 meters and 3.5 KW on 6 meters. These ratings are good for up to 2 to 1 SWR.

The MIL SPEC transmission line used to make the line isolator uses: silver clad copper center conductor, silver covered shield, solid Teflon dielectric with a voltage rating of 1900 rms volts and temperature range of -55 to + 200 degrees centigrade.



BllI-HF-250

Model: BLLI-HF-250
QRP / Low Power Line Isolator
$29.95



The BLLI-HF-250 is a 50 ohm inline isolator with two SO 239 connectors for coupling your coax.

The line isolator is used to isiolate any RF (common mode) that may have worked its way back to your station. It uses the Guanella current/choke design.

The power handling capability of the line isolator is conservatively rated at 250 watts from 160 to 6 meters . It will safely handle peek power ratings of up to 350 watts. These ratings are good up to a 2:1 SWR.

The MIL SPEC transmission line used to make the isolator uses: silver clad copper center conductor, silver covered shield, solid teflon dielectric with a temperature range from -100 to +200 degrees centigrade.

If you are using a transmatch, connect the line isolator to the input (station side) of your transmatch. Do not place it on the antenna side of the transmatch. Most matching networks that have a balun installed use a 4:1 voltage balun. These baluns are usually not adequate for choking RF from working its way back to your rig.



BL-HF-250

Model: BL-HF-250
QRP / Low Power Balun
$32.95



The BL-HF-250 is a 1:1 current/choke balun with an SO 239 connector for your coaxial connection.

These are very efficient baluns and use low permeability, less lossy ferrite than most other baluns on the market today. Less losses means less heat on the ferrite material, less chance for balun failure and more power delivered to the antenna.

The power handling capability of this choke is conservatively rated at 250 watts from 160 to 6 meters . It has a peak rating of 300 watts. These ratings are good up to a 2:1 SWR.

The MIL SPEC transmission line used to make the balun uses: silver clad copper center conductor, silver covered shield, solid teflon dielectric and a temperature range from -100 to +200 degrees centigrade.

The balun is enclosed in UV rated material. The hardware is also stainless steel so NO RUST! There are also two drain holes in the bottom of the enclosure should any water migrate its way inside the enclosure.



GU4-HF-5KW-A GU4-HF-5KW-S

GU4-HF-5KW-A ($83.95)

GU4-HF-5KW-S ($83.95)





The GU4-HF-5KW is a 4:1 Guanella Current Balun with an SO 239 connector for coupling your coax and machine screws for connecting parallel feeders or your antenna wire.

These baluns maintain a flat SWR curve over the entire HF frequency range when terminated into a 200 ohm matched load.

Model version "A" is designed to be used at the feed point of your antenna, such as a folded dipole or any other 200 ohm antenna. It can also be used at the shack end of your parallel feeders. Both version "A" and version "S" use the same internal parts and can be interchanged. Version "S" does not have any eye hooks and the terminals for your parallel feeders are on the top of the enclosure instead of on the sides.

These are very efficient baluns that are better than 98% efficient from 160 to 6 meters. It uses dual ferrite cores and can handle 5KW continuous and up to 10KW peaks in a matched condition. The dielectric of the wire in conjunction with the teflon tubing gives the balun a voltage rating of 10,000 volts. These ratings are good up to a 2:1 SWR.

The balun is built inside a nema enclosure and will hold up in the harsh UV environment. The hardware is also stainless steel so NO RUST! There are also two drain holes in the bottom of the enclosure should any water work its way inside.

If the balun is mounted vertically, coax connector aiming down, the enclosure is considered water resistant and no additional protection is needed. If the balun is placed on a flat surface and no additional protection against the elements are provided, the bottom half of the enclosure could possibly fill with water over an extended period of time. It is suggested that the balun be placed inside a waterproof enclosure. The "S" model has two extra drain holes so this problem does not happen, but it is still a good idea to provide an extra waterproof enclosure.

This is an ideal balun to be used on an Off Center Fed Antenna.

GU4-HF-1KW

GU4-HF-1KW
4 to 1 Guanella Current Balun
Medium Power
$49.95



The GU4-HF-1KW is a 4:1 Guanella Current Balun with an SO 239 connector for coupling your coax and dual banana jacks for connecting parallel feeders.

These are very efficient baluns and maintains a low SWR curve over the entire HF frequency range when terminated into a 200 ohm matched load. It uses a single ferrite core and can handle 1000 watts continuous and up to 1500 watts peaks in a matched condition. These ratings are good up to a 2:1 SWR.

This balun is not waterproof and is not meant to be left in the outside elements uncovered. It can be used outside if placed inside of a waterproof enclosure.
