I don’t have the facilities to measure IMD, but in 3 years I’ve never had an on-air complaint. I also don’t have lab grade power measurement available, but there appears to be little loss in the combiner based on basic external wattmeter measurements. I don’t operate 6 meters, but 160 – 10 is no problem.
The W6PQL splitter/combiner are the units he makes for his two pallet amplifier kit. So they are being used well below the designed power level.

Are the amps being driven hard wire / parallel at the inputs or from a power divider? And how are the outputs summed? Power divider? How much loss is in the output summing network? And is it broadband 160M - 6M? Another thought is to use a broadband balun and drive the amps in push-pull. Both input and output likewise. Hummmm...... I'll have to think about that. All interesting questions. 73 Bob, K4TAX > Yes you can.
