They are NOT traps, they are loading coils. I've used them, measured 
them, and modeled them. They are well built, and the designs are good. 
I've run them under contest conditions at legal limit. The current owner 
is not the original owner. I did biz with the original owner and found 
him very good to deal with.

I've only used designs with a single pair of loading coils, first for 
80/40, later for 160/80. SWR bandwidth is good on the higher band, very 
narrow on the lower band. I would expect designs using more than one 
pair of coils to be pretty narrow band on the lower bands.

I do NOT recommend their "baluns."
