I wanted to be able to copy the occasional FM "EasySats" as well as the International Space Station, non-trunked public service channels, NOAA fax transmissions on 137 MHz and whatever else might get my attention above the 6 meter band.
Reception has been quite well even though the antenna is mounted only 6 feet above the peak of my roof on a chimney mount. I'm able to copy many of the AMSAT satellites as long as they are above 30 degrees in elevation; and I can also receive aircraft transmissions while they are still on the ground, 11 miles away.
The ad for the antenna says that it is suitable for transmitting on several V/UHF ham bands. I was skeptical of this, but, to my surprise, it does indeed present a low SWR on the three bands I am able to sweep with my nanoVNA (soon to be upgraded).
Here are the results of a 100-470 MHz sweep:
