Andy,

I don't have the LDG TW-1, but everybody I know who has it is quite 
satisfied with it.

I am unclear as to your problem.  It sounds like you have an antenna which 
tunes on 160 and 80 meters, but you have a high SWR on 40 20 15 etc.

The TW-1 is only a measuring device.  When it shows a high SWR, have you had 
access to another SWR meter?  Do you get similar readings with it, or is the 
meter at fault?

If the readings are the same, then the TW-1 is fine and you need to look at 
possibly the SGC tuner or maybe a change in feedline length.

I'd suggest putting an antenna analyzer on the antenna in question and 
seeing what results you get.  IT may be that the suggested length is not 
quite right, as it can interact with surrounding objects.
