If you had an exact timing for the outage, would that
have told you the beam-width of your antenna?

GPS has some 36 or so satellites in a Medium Earth Orbit (MEO). Blockage, if it can even occur due to the nature of the receiving antenna, of a single one for a few minutes will have no discernible effect in my opinion. 73 - Mike
