You should always isolate the (poor) remote ground of an antenna used for receiving from the station. There is no code that says it should be connected to the station. I isolate the grounds of my Beverage feedpoints from the feedlines, even though they are thousands of feet from power lines. The code problem is with grounds at your house, not with the ground at the antenna. NEC requires all cables entering the house and all grounds at the house to be bonded to a common point. You should not have a rod outside for the hamshack ground that is not bonded to the utility entrance ground. The logic behind this is any surges or lightning hits will not elevate the two grounds to different potential, and create a current path flowing through the house. This is NOT a problem with the ground at the antenna, assuming that ground is some distance from the house and you have a reasonable length feedline to the house. What you should NOT do is float the station without a ground, and you should not have the ground for the station float independently from the service entrance ground. If you see a noise change from adding a ground at the house it means you have a feedline problem, radio problem, or balun or ground quality problem at the antenna.
