I'm giving up on this for the time being until I either get an antenna analyzer or try a coax choke.

I have absolutely no idea why two different SWR meters are showing different readings for different frequencies on the same length of 80' coax. One showing the SWR is lower on low channels, the other showing it's low on high channels.
Both meters test perfectly fine into a dummy load so that leads me to think maybe one of the meters (probably the cheapy one) is being effected by coax common mode current even after the long coax run.

I just went with an SWR reading somewhere between the two meters and what my radios built in meter was happy with, which seems to work okay for now.
Really I shouldn't freak out over this, everything is below 1.5:1 for CB, but I know it can be better and eventually peaked for midband once these mysteries are solved.

The ladder or wire hanging off the tower still has a slight improvement in lowering "swers" for some bizarre reason

[QUOTE="darklife, post: 733771, member: 31545"] I'm giving up on this for the time being until I either get an antenna analyzer or try a coax choke. I have absolutely no idea why two different SWR meters are showing different readings for different frequencies on the same length of 80' coax. One showing the SWR is lower on low channels, the other showing it's low on high channels. Both meters test perfectly fine into a dummy load so that leads me to think maybe one of the meters (probably the cheapy one) is being effected by coax common mode current even after the long coax run. I just went with an SWR reading somewhere between the two meters and what my radios built in meter was happy with, which seems to work okay for now. Really I shouldn't freak out over this, everything is below 1.5:1 for CB, but I know it can be better and eventually peaked for midband once these mysteries are solved. The ladder or wire hanging off the tower still has a slight improvement in lowering "swers" for some bizarre reason :P [/QUOTE]
