OK, we are going to try it ourselves without professional installers and with smaller to see if they get anything. Would
http://www.costco.com/Browse/Product...rodid=11646220 be a good choice to start from Costco?
If not, then what specific ones to get that are returnable from local retail stores to see, buy, and be able to return easily if these don't work.
Also, where can I find professional antennae installers for La Habra Heights, CA 90631?
