OT TV antenna

A couple days ago the wind blew hard enough to break the 10 year old
supports on our TV antenna mast. We have a tile roof and a falling antenna
could get very expensive so I took the damn thing down.

Then I took a trip to Radio Shack and found a long bar like "amplified"
antenna that I could just tack on the gable eves of the house.

In the past ( old antenna ) we got several channels with 3 and 6 ( my
beloved PBS) being the weakest and 10 and 13 being among the strongest.

Now, I get 3 and 6 far better :-) but don't get 13 worth a damn.

I know less than nothing about such things, and don't watch much TV so I'm
not going to pay for a dish or erect another tall mast antenna like the one
I took down. But, I'd like to get 13 ( CBS ) to watch Andy Rooney tell it
like it is G Anybody got any clues on why this antenna would reverse my
reception? I "think" all the towers are towards Sacramento, north of me,
btw.

Suggestions? from somebody that understands how Andy get into that box in my
living room ?
