Can anyone tell me about this RoomCap Antenna?

The best I can find on the antenna is a picture of what looks like a
piece of PVC with a capacity hat on it.

I keep getting advertisements on the email reflectors and when I check
the website, it asks for me to email for more information. I have
done so several times and never received a response.

What can you all tell me about this antenna?

Thanks,
Buck
