The performance of the dummy load as a dummy load wouldn't be good if it were a 2:1 mismatch
At that rate, you probably pulled the wrong dummy load off the storage shelf; you picked the 25 Ohm or the 100 Ohm model ...
Yeah, that's what I meant. If you take the context of his original post, that's what he's talking about- the "SWR performance."
Why the differences?
1.You are measuring in different places.
2.All meters do no have the same accuracy.
3.'MomaNaure' doesn't like you.
Take your pick.
A shortened antenna is rarely a happy one.
A poor radio with a good antenna is often better than a great radio with a compromised antenna.
jfwiw dept, 1.5 :1 = 6% loss appx 6 watts out of 100.
2:1 =11 watts lost.
wont be much on an s meter huh.
thats why i always use the internal tuner with everything outside..radio sees 1:1 and max power or what you set.
How did you calculate those?
Pref/Pfor = ((SWR-1)/(SWR+1))2
Okay, so the percentages quoted by W9WQA is the ratio of reflected to forward power. Surely that's not the same as "watts lost". Other than resistive losses doesn't it all end up in the load eventually?
