R52 diversity

hi

when i conect the r52 to the auxilary antena conector i got better signal then the main antenna conector
anu idea?

it depends on what antenna port you have selected in wireless configuration. also, what do you consider a better signal?

could you explain: where is aux. and where is main connector?

and your r52 settings in RouterOS?

For R52 ‘antenna-mode=antenna-b’ uses ‘aux’ connector.
