They do show minimal specs, not a isotropic map like you may be used to

for ham antenna adds but 12db, 30 degree angle of radiation Its fed with
type N-male

connector. up to 50 watts input power 1:5.1 avg SWR @2.5 Ghz

choice of feedline of course would be up to you but I wanted to get the

thing up and running so for test purposes I used 20 feet of old RG-58

30 mw input and have it pointed at my ISP 4.5 miles away that's how I

get 1.5 Mb internet service

It certainly looks well-constructed, but I'd have a lot more confidence in
Cantenna's products if they had measured (or even simulated) radiation
patterns and calculations. They also don't mention their feed arrangement
which could make a huge difference in actual performance.
