Making sure antenna is working Answered

I have a FT950 connected through a coaxial cable to a Buddipole antenna setup as a 40 Meter Dipole. I have a brother in Arizona and I heard him on a 40 meter frequency a couple of days ago but he could not here me at all when I was transmitting.
How do I know the antenna is woring and actually transmitting the signal ?
I have a Antenna analyser but quite frankly don't know how to use it to see if the antenna is actually sending the signal
Can anyone help and advise me how to hook up and use the Analyser ?
