Directionality and gain: yagi versus parabolic antenna
First lesson: Never trust Aliexpress product listings. That's an imperative.

Second lesson: Generally, the larger an antenna is relative to the wavelength, the more gain it can have. 

That's why your home satellite dish isn't as highly directive as let's say this one:



 

so, first thing not to believe in the Aliexpress listing is this:



is this the real bandwidth? 700 MHz to 2700 MHz is a bandwidth of 2 GHz, at a center frequency of 1.7 GHz. In other words, this would need to be an ultra-wideband antenna (we can currently hardly build any antennas that can a bandwidth that is much larger than 1.1 of the center frequency). Yagis aren't ultrawideband.

So, what they don't tell you is that this antenna might work well for some of the bands they list below, but not as good for others. In fact, I wouldn't know how a yagi, whose design depends very much on the relation of wavelength to element spacing, could work for such non-integer-factor related bands. This sounds like a scam, in fact.

Now, aliexpress antennas for some reason (cheapness cost, of course, and seller competence) don't come with a measurement of efficiency over the specified frequency range.

If anything, that gain would be achievable at the upmost end of the frequency scale – again, gain scales with relation of antenna size and in a Yagi design, the number of elements that help reactively "focus" a delayed version of the excitation from the last element. Even so, I'd heavily doubt the 28 dBi.

So, rest assured, that, the workings of mythical antenna smiths nonwithstanding, your dish will outperform such a 30€ antenna scam.



As I said, often, legislation limits the Effective Isotropic Radiated Power. That is, you have to subtract the gain of your antenna from your transmission power. Hence, in transmit, you gain nothing by having a high-gain antenna. 

Whether or not that's the case in Norway in the cellular bands is unbeknownst to me.
