I know, I know...it's been forever since they went out of business.

But I'm hoping somebody here has a pointer to gain specs for the HBU55...I'm particularly interested in how bad its low-VHF specs were.
It seems that the high-VHF was around 11 dB over reference dipole...

I'm using one of these, and it does pick up VHF 5...but it misses potential channels at 2, 4, and 6. Trying to understand what improvement is possible with a replacement antenna...(I'm already using a quality preamp, so there's no potential there.)

Thanks for any info / pointers you can provide at this late date.
