I installed this on my office computer & could not pick up a single station on AM or FM band, I tried re-installing it, re-positioning the device & all I ever got was static. I took it home & tried to install it on my desktop & laptop---nothing but static. My $9 clock radio works fine in the office, but not the Radio Shark. I live in a major urban area with plenty of stations within range & even plugged into an external antennae this junk would not work. Please note the range of customer reviews on this product---most people have given it bad to mediocre reviews. It is a total & complete waste of money.
