The Tri Band is definitely a fantastic scanner antenna. I've been doing some comparisons and it beats all I got. I ordered another one to use as a base antenna. It'll sit on top of my ground plane concoction. 45' with LMR-400. If I run across lower loss cable, I'll swap it out.
My Super M Ultra works great on all bands except VHF. Surprisingly, it's a little deaf, which surprised me. The biggest surprise, is how well it works on low band.
