Someone else suggested that i place the meter
right at the cantenna, to at least exclude the patch from meter to
dummy load.

No, you don't want to do that. Put as much loss as you can between the meter
and the Cantenna. 100 feet of RG58 will have about 6.5 db of loss. It will
make your load a lot closer to 50 Ohms. There are Tables that show SWR as a
function of cable loss for a given mismatch. One chart that I have in
"Reference Data for Radio Engineers" shows that with a load SWR of 1.4, and
6.5 db of cable loss, the SWR at the driving end is around 1.075. Note that
you DO NOT want low loss coax.
