Hi Tom,

The BL2 does exactly the same thing as the BL1, but handles more power 
(up to 250 watts) and has a 1:1/4:1 switch. Both baluns have the same 
very flat response from 500 kHz to 55 MHz. If you think you'll ever use 
more than 100 W, or if you routinely use 100 W with high-SWR loads, I'd 
go with the BL2, which uses a core that's twice as large as the BL1's.
