Car is 02 Toyota Celica
Was originally thinking one of these:
hidden inside fiberglass front or rear bumper. Probably use the magnet base to attach to the mounts for front or rear bumper.
Then I saw, on some modder TV show... The person used something like this
strapped to the underside of their trunk. Celica has a false parcel shelf and a big window above it, so I thought this may work well.
But, I know the story about vertical antennas layed horizontal. So possibly either vertical antenna and just stand it up on the parcel shelf.
Then I was looking at the "ceiling" type, like this
Basically, I want the best, longest range reception possible. However, I don't want to permanently alter exterior of car and magnet-base would look bad. I'd consider external if I could find a fin or similar. Of the above, what would work best? Advice would be totally welcomed and appreciated.
