I just happen to have a couple of unicorns squirreled away in a drawer somewhere that I bought for a project at home but never used. I almost threw them out last fall when I moved into my new lab space as I'd already written off the investment.
I can re-tune them as needed, but, I have to tell you, the Jointenna is no TinLee AC7! The single channel pass filter on the UHF ones is wide enough to drive a semi through, several tens of MHz wide. You're lucky if you can get a 20 dB notch on the channel reject filter. The VHF one I checked was much cleaner.
It's been a few years since I played with them. I'll see if I can dig them out tomorrow and see what's there.
