Right, who in LA had seen an offair antenna since 1985? Abstract art.If an indoor antenna is not doing the job, you most likely need an outdoor antenna. If an outdoor antenna is absolutely not possible due to living in an apartment or such one can mount a larger antenna that is usually meant for the outdoors in a window or appropriate location inside. I had to do this in Los Angeles and just told people it was modern art.
An amplifier can make up for signal loss in a long transmission line but can not create signal that is not there.
I was given one of these from a guy selling and moving out of his house. It's ok, but it's not the best by any means. I wouldn't pay to buy one for the price they go for.
