Ira how is your reception away from your neighborhood or at the beach at least? Remember the last time I was down there I mentioned the fact that you were surrounded by so many metal structures in close proximity, let alone living in one is a major contributing factor.
You have two factors here...
1. Radio wave absorption and dispersion due to the metal structure.
2. Upon said absorption, signal to ground effect due to nautral grounding of metal structures when contacting the earth.
My recommendation to you was to get an external Yagi antenna. Looks like this:
Then run a sheilded cable where you could either clip to your rod antenna or if your box had the option connect to antenna leads.
Other than that, maybe a powered indoor antenna or leave the neighborhood or head to the beach away from the trailers.
