Definitely quality materials and workmanship. After downloading the English version of the instructions it was simple and straightforward to deploy. I made a bracket on which to mount the antenna which in turn mounts to my transit tripod. I own about 6 Comet products and am happy with each and everyone! This antenna does require a little fiddling with to get dialed in, but once there it preforms great. 20 meters seems to be the lowest swr of the 9 bands available. I was able to achieve 1.3 on 20, 1.7 on 80 meters and 1.5 on 40 meters. I didn't try the other bands. Overall I would recommend this antenna for a portable backup antenna... I do not intend to use it primarily, as it doesn't preform as well as my efhw or even my random wire, but it's small, compact, lightweight and works good enough to carry on the trail as an option or emergency backup.
Great antenna at a great price!! The antenna works great connected directly on my Icom IC-705 radio. And it easily tunes to the selected band. Great Antenna!!!
