Glad to see others that are serious about the Low FM band. Here in West Tennessee, the Low FM band is very important, since THP operates on several frequencies around 42mhz and 45mhz. The following is what I discovered through trial and error......
I agree that the "Scantenna is so so." It works great for VHF/UHF though, and looks great...hangn' off the side of my tower.
What I am using for Low FM is a good Wilson magnetic CB antenna for one radio, and a homemade dipole I was using for HF. It is 45 feet on each side, horizontal and I can hear Nashville THP 100 miles away. The other scanner is using a Saturn B-100 CB antenna that sits at the top of the tower, next to the Scantenna. Above that, a Starduster. The B-100 works very well for Low FM and I noticed that I can hear THP on one radio (same freq) and not the other. All three scanners have their own mind, I guess....maybe because of repeater locations in West Tennessee, but the best is the homemade dipole, using 14 guage copper wire, strung across from tree to tree.
The next best is with the Workman (Saturn) B-100 that does not require a groundplane. It works better for me as a Low FM antenna than when it was used for the CB. The standard Wilson magnetic whip is OK, but the other two are great.
