Yes, but the reflected power reading is more accurate than the standing wave reading. It's because the swr/power meter is usually installed close to the radio instead of the antenna. With the antenna being far from the radio (usually 18ft), the reflected power going through the coax can cause a lower swr reading. That's one of the reason to use good quality coax because of the db per foot loss. Unfortunately an swr meter won't tell the whole story. Since the OP doesn't have an analyzer, it makes it harder to know what's changed in his antenna system.
Yeap very true..Also that jumper used could be an issue of sorts,the good ole swr meter itself is another issue...
I found out the hard way was to read,listen to those who seem to know,watch vids ect and i ended ul doin more than i expected...Cb is just not plug n play thats for sure,its a constant learning hobby..
When i learned about my analyzer being able to read from radio side or ant side i saw a difference in what i thought my radio set up was doin..Still not alot further ahead but im slowly gaining ground(no pun intended)
