simple way to check if burned module devo 7e

hi, i did range mod on my devo 7e but unfortunately i usend to play binding and setting model with quadcopter connected in cleanflight without antenna, now seems to have poor range is there a simple measurement to do to check this, a multimeter to check on antenna connector or something else?

solved, dismantled antenna and module was the wire to sma connector that was damaged by hot kind of glue used to fix in place.does not was other than this anyway i yet ordered new module and used this
