yagi beam for 70cms or pmr 446

Hello people whilst looking around eBay came across a beam that covers the 70cms band including pmr 446 and thought i would post it on here. Looks ideal for for taking to the hills mobile or for a handheld. Has anybody bought one? What do you guys think? Will it be effective? its got to be better than the standard antenna on a handheld?

And there is a guy here that makes antennas that come with a fibreglass pole for some SOTA stuff. I have them here and work well on 70cm and PMR so they say. The site is listed here.
Sorry that its in German, but thats where the man makes them.. He also makes excellent antennas for CB, he makes them to order as i have a UKFREQ made.. Works superb.
