i was reading some technical spec's on a ladder line feed.

the numbers showed it had sorta hi swr around 5 yet the power loss was
really low for it's run, like about 2watts

this confuses me, i always thought that high swr automatically ment
'loss' so what is the piece i am missing?


even stranger was the same equation as above but run for coax, which had
lower swr but higher power lost, which i then attrib to something like
the resistane of the coax?


boy i am mixed up

hmm thanks to all that replyed, i guess i do understand what you
explaned, as it was straight fwd, but i am still feeling strange about
it, i'll run the numbers again, and if i don't 'see the light' perhaps
i can post it more specifically here again

guess the part that bothers me is having such a high swr in the ladder
and such a low loss, i followed mathmatically what youall said, that
adds up, but justt seems well i guess i just thought mentally that say a
5 or 6 swr had to mean some loss greaater than 4watts "100ft run
don't know why i thought that guess it depends "" on all the factors
you guys mentioned

cool thing we have modeling sofware

the posts are starting to add up, espically the latest posts, very
greatful for all the help i can see the math now, but need some more
quality time to think/study and try to see what is going on to fully
digest

man i am ****sed i didn't get to learn this stuff in school or anyplace
elese it's all super neetOhh

thanks all
