Practical side only. Assume you use a random wire antenna. AT in K2 or KX3 will not match all bands directly. It will match with BL1 or BL2 in 4:1 mode. This is because: 1. After transformation, the impedance is more manageable to KAT2 or KXAT3. 2. Loss in balun. Mainly on lower bands with short antennas.
Whenever I have space for BL1, I use it. It is no brainer as I prefer the match than no match and balun overheat than AT overheat. Heating occurs mainly at bands were the wire is too short. New transformers can have extremely low loss. A 64:1 transformer used for 40-10 or 80-10 endfeds at myantennas.com is just warm at a KW level.
