Hi Fred,
I did use a lo profile sicular polarized antenna. This was mounted on a
magnetic mount. It didn't have great gain, but got your
signal out. I no longer have this antenna, for it was loaned to me to
experiment with . We use a 5/8 wave antenna mounted on a magnetic base.
When we enter the garage , we either reach up through the sun roof and
unscrew the antenna or let it get knocked over when we enter the garage. 73.
