I want to use a mobile cb antenna on my house. I have mounting
brackets and already have the power converted. I need a way to use my
mobile 3/8 flex antenna outside and have an attiquate ground plane to
keep my swr down. I saw a "tristar" on the internet which said it
acted as a ground plane. I have not gotten an answer yet, but
hopefully I will. I do not want to buy an no ground plane antenna
because I will eventually move my old antenna to my truck when I get
one. What can I use as a ground plane, and spending minimal amount of
money.

Thanks in advance

Greg
