As an amateur radio license holder, part of my role is to build and study antenna at the same time try to understand how radio waves works.
I found it a joke that lots of people fall for parabolic antenna which has no certification, BS specs, willing to pay certain amount of money just to boost the signal. These people have no knowledge of the antenna specs, type of cable use and lengh of cable.
It's true what you said, good cable will have more copper on its core. The more thickness the copper, more harder to bend.
certification might be too costly for low demand low volume consumer product.
yea, no way to verify the spec whether it's BS or not. consumer only can trial and error.
some people who have the need might not have the privillage to have relevant knowledge, so what they can do is just buy and try. if it works, then great; if not then resell it.
one thing i would like to highlight that, always share your own experience or knowledge, and answer other people's questions in online forum like here or reddit.
why online forum? it's friendly to search engine, local relevance and well archived.
why not other social media? unable get search result from closed group, tons of clickbaits, flooded with selling posts, less on-going/follow-up discussion, time-consuming for info gathering if it's in form of videos/reels, and most annoying their own search engine and content suggestion algorithm. fxck that sh*t.
in addition, malaysian punya review culture in e-commerce platforms: blank. irrelevant. bagus. mantap. fast/slow delivery. barang dah sampai belum try 5-star review.
so how could a layman consumer obtain relevant knowledge and experience from others.
once again, i hereby to urge forumers sekalian don't hesitate to share your constructive suggestions, user experience, device perchase price screenshots, telco plan subscription, tips and tricks for optimization, blah blah blah.
by doing so we could have new and updated info input from real users, accelerate the adoption of latest tech, more choices of device, bring the cost down, and eventually improve the user experience.
sharing is caring.

For my self. Build in antenna in the modem is sufficient enough without losing any more dbi.
Having an external antenna putting me at risk of lightning that may not only damaging my modem, will also damage my router and any computer connected via ethernet cable.
Investing on external antenna also not feasible to me as i already get good speed and good signal though it can be better.
Having an external antenna is not feasible for many people too.
that's why i have been sharing some tips here to improve the speed.

That is quick a crazy setup for home wifi... hahahaha
it's straightforward and effective.
there are people using PoE ceiling mount industrial access point for better aesthetic.

Im gonna find if the branch I register my home broadband has this new router. Office celcom 5g just finish 2 years... time to reduce from RM149 to RM68.
I'm wondering incoming umobile 2nd 5G network could do 200MHz bandwidth or not with DNB.
current DNB dapat 100MHz (3400 to 3500 MHz), half of n78
umobile dapat 100MHz (3500 to 3600 MHz), another half of n78
https://theedgemalaysia.com/node/733606If i'm not mistaken and please correct me if i'm wrong, Huawei H153-381 is using Balong 5000 modem which can do 200MHz Sub-6GHz.
so i doubt if umobile has already planned for 200MHz 5G network, by offering Huawei H153-381, haha.
while mmWave spectrum allocated i have no idea if there is any chance for telco to implement. i guess mmWave is for industrial private usage.
little info for Qualcomm 5G modem Sub-6GHz bandwidth:
5G "Phase One" (Release 15) Modems - Sub 6 GHz Bandwidth:
X50 - 100 MHz (no carrier aggregation) *phased out, nsa only, eg: nokia fastmile 1
X55 - 200 MHz (limited 2x 5G carrier aggregation) *can't CA TDD with FDD band, should be ok when both 100MHz are n78
X60 - 200 MHz (flexible 2x 5G carrier aggregation)
5G "Phase Two" (Release 16) Modems - Sub 6 GHz Bandwidth:
X65 - 300 MHz (flexible 3x 5G carrier aggregation)
X62 - 120 MHz (flexible 2x 5G carrier aggregation) *so the best u can do is 20MHz from n28 (if got this sa network la) + 100MHz from n78
X70 - 300 MHz (flexible 4x 5G carrier aggregation)
5G Advanced (Release 18) Modems - Sub 6 GHz Bandwidth:
X75 - 300 MHz (flexible 5x 5G carrier aggregation)
X72 - 200 MHz (flexible 3x 5G carrier aggregation)
for Mediatek,
m70 (the modem integrated in T750) - 200 MHz (flexible 2x 5G carrier aggregation)
m80 (the modem integrated in T830) - 300 MHz (flexible 4x 5G carrier aggregation)
