This is a late post, but I got the Spectra yesterday. I'm impressed w/ the performance on vhf-low. I haven't cut the lowband whip, either. Still trying to decide. I think I'll cut it more toward the center (40mhz). I generally listen between 39 and 46mhz on lowband.
I've tried quite a few scanner antennas over the years and this is by far the best on vhf-low. I've noticed some improvements w/ uhf and vhf-hi as well. Haven't tested 800, yet. Hope this helps.

p.s... It is ugly, but it does work!!!
