RF Chokes are important to get right. Therefore, Greyline seeks wisdom from expert RF engineers with know-how in ultra high quality and results. Knowing what is on the market we target our designs for 'best of breed' for each antenna system. Made in the USA by small ham radio owned businesses. 

By aligning with multiple well-respected antenna designers and RF engineers we find a better insight into what's available on the market today. We then match the RF Choke designs (current baluns, RFI line isolators, baluns) around each antenna system's requirements.

By focusing on smaller, peer owned boutique businesses, we are doing our part to share our projects in a niche marketplace and continue to find improvements in the details. .

Our chokes are rated between 500W to 10 kW. They are typically installed before the Remote Tuner at the base of your DX Flagpole Antenna or HF Vertical Antenna. Also, on the radio side to mitigate any QRN, or noise captured along the coax back to the radio station, RF Chokes can be placed after the radio or after the amplifier.

Many operators add a second RF Choke, 500W or 3500W, immediately after the radio or amplifier. Remember, every dB counts!
