Review BALUN DESIGNS LLC Feedline 5kw Isolation Mhz 54 1.5 Common Choke Mode

The 1115i Feedline 5kw Isolation Balun 54 1.5 Common Choke is a high-performance balun designed for use with 5kw feedlines. This balun is equipped with a common mode choke, which helps to reduce common mode noise and improve the overall performance of your antenna system.

The 1115i Isolation Balun is made from high-quality materials, including a 54mm ferrite core and 1.5mm copper wire. The ferrite core is carefully selected for its ability to effectively reduce common mode noise, while the copper wire is used to ensure reliable and consistent signal transmission.

The balun is designed to be easy to install, with a simple screw-on design that allows it to be easily attached to your feedline. It also features a high power rating of 5kw, making it suitable for use with high-power antenna systems.

In addition to its noise reduction capabilities, the 1115i Isolation Balun also provides isolation between the feedline and the antenna, helping to prevent feedback and other interference. This makes it an ideal choice for use with a variety of antenna types, including Yagi, Log Periodic, and Dipole antennas.

Overall, the 1115i Feedline 5kw Isolation Balun 54 1.5 Common Choke is a versatile and high-performance balun that is well-suited for use with high-power antenna systems. Its ferrite core and copper wire construction ensure reliable signal transmission, while its common mode choke helps to reduce noise and improve overall performance. Its screw-on design makes it easy to install, and its high power rating of 5kw makes it suitable for use with a variety of antenna types.

1. High Power Handling: The balun is rated for 5kw of power, making it suitable for high-power applications.

2. Isolation: The balun provides good electrical isolation between the feedline and the antenna, reducing the risk of interference and improving system efficiency.

3. Common Mode Choke: The common mode choke helps to reduce common mode noise, improving signal quality and reducing the risk of RF interference in the feedline.

4. Durable Construction: The balun is built to withstand harsh outdoor conditions, making it a reliable choice for outdoor antenna installations.

1. Price: The balun is relatively expensive compared to some other balun options on the market.

2. Size and Weight: The balun is relatively large and heavy, which may make it difficult to install in some locations.

3. Limited Compatibility: The balun may only be compatible with certain types of antennas and feedlines, so it's important to check compatibility before making a purchase.

The 1115i feedline 5kw isolation balun 54 1.5 common choke is a reliable and high-performing balun option for high-power applications. Its isolation and common mode choke features help to improve system efficiency and signal quality, while its durable construction makes it suitable for outdoor installations. However, the balun's price and size may be a concern for some users, and it may not be compatible with all types of antennas and feedlines. Ultimately, whether or not this balun is a good fit for your needs will depend on your specific application and requirements.

If you're looking for a high-performing balun for a high-power application and are willing to pay a premium for quality, the 1115i feedline 5kw isolation balun 54 1.5 common choke may be a good option for you. However, if price or compatibility are concerns, you may want to consider other balun options that may be more suitable for your needs. It's always a good idea to do your research and compare different options before making a purchase to ensure that you're getting the best product for your money.

Details:

Power rating 1 to 35 mhz 5kw, 35 to 54 mhz 4kw. Tests completed utilizing precision 50 ohm non inductive load core material custom mix low permeability ferret by fair rite products for maximum band width .

Silver flashed braid and conductor with solid Teflon dielectric. The model 1115I is a single core design that will handle 5kw 50 duty cycle, 3kw continuous at resonance and provides high common mode impedance and a large effective core area for excellent performance.

Problems can be more evident in Sb mode because the microphone audio line and mic circuitry may be very sensitive to RF. 06 across the entire hf band, transformation is perfectly flat, return loss is typically BMW and choking impedance peaks at over 5k ohms.

This is especially apparent when using end fed antennas, high impedance feedline, or a poor ground counterpoise. You can even get an RF burn from the mic in worst case situations, not to mention from the chassis or other equipment used in the system. When your transceiver and other equipment in your shack acts strangely, it is probably due to stray RF pickup which produces a common mode current problem.

Winding type single core, coaxial wound 1/1 current Balun winding material mil spec 50 ohm coax rated 19kw 1mhz, 9kw 10 mhz and 4kw 50mhz. This unit can be installed at either the rig or the antenna or in severe cases, at both locations. Balun is configured with two so 239 connectors.

Alternate connectors and mounting options are available in the accessories section. Usable frequency 1 to 54 mhz insertion loss less than.

Balun Designs. While common advice may be to improve the station's RF ground, the root of the problem is poor isolation of the feedline from antenna currents. 02db connectors so 239 connectors are silver plated with Teflon insulation.

All ratings based on resonant antenna. However, this is not the best solution and a better way to eliminate RF pickup and induced common mode currents is to electrically isolate the rig from the antenna by using a choke Balun more commonly know as a feedline isolation Balun. Balun Designs builds with a custom core mix that offers the best possible combination of RF choking and absolute minimum insertion loss.
