Your situation is really no different than Pete's in specific regard to the LA channels which is what you asked about. What worked for him will also apply to your location with only minor local variations.

You're still staring point blank into a mountain that has both TV and FM stations on it and the desired signals are directly behind that mountain. Unless you're prepared to invest similar time, effort and money as Pete did, your prospects for reliable reception of the LA signals are extremely poor.

We can only base our recommendations on the combination of the data available (with it's limitations, both known and unknown) and from our collective experiences. WE's recommendation in post #2 is very appropriate, you may find someone local whose experience is such that he's found a combination that works well enough for him to stand behind.
