SWR affects how much power a Common Mode Choke can handle.  To see if this affects you, check out: SWR, Insertion Loss, and Power Handling

Our chokes are carefully measured and fully characterized for Common Mode Rejection Ratio (CMRR), Insertion Loss, and Power Handling.  Our products are ventilated to keep the ferrite cool, which allows higher power and duty cycles, especially important for FT8/4 operation..  

We design our chokes to meet Specific Performance goals.  Rarely does "one size fit all".

Black Beauty Broad 160-10 is optimized to provide the best CMRR possible across the whole HF frequency range.

Black Beauty HD Low 160-40 is optimized for 160m and 80m.  It provides more CMRR on those bands than a broadband choke - more than 50dB.  It also has extremely low insertion loss, which means it does not get hot and can, therefore, handle more power.

We certainly do.  We provide a 30 day "No Questions Asked" return policy because we want all of our customers to be happy with all of their purchase.  We also provide a 2 year warranty.
