I've been testing all antenna, bare in mind, it work for me, but might not work for you.


All the indoor antenna/wifi amplified are no good. Unless it's for your own indoor coverage e.g better wifi strength. No improvement for source DL/UL.

Outdoor antenna Log type, I tested probably work best performance wise best DL/UL out of any other outdoor antenna.
Second would be the polarization Parabolic Grid Gain Outdoor Antenna that everyone was talking about I got mine from taobao and it perfect for rural place.

If you are looking for outdoor antenna. B618 isn't good because the internal antenna is wasted. Get a compatible for 4G+ and support a lot of bands frequency router gateway. That is what I found work your RM as the performance probably top of the roof for what a user can improve on hope this help someone else.

POST AT OTHER TOPIC BY ME:

Have to clarify log is good if you only have 1 direction focus to connect to, e.g Band 5 tower at WEST and for malaysia I feel like it will not last long in this weather 32+celsius everyday because the materials circuit board is literally out there to get toast everyday. NOT SURE it's just my opinion common sense? Proof me wrong if you think it's not.

polarization Parabolic Grid seem to be durable for such hot weather and in reality if you are in the city and have 2-3 towers to choose from GRID will have better coverage for receiving larger direction like west + north towers in reality you want 4G+ 2 bands to get TOP SPEED. This will be way better than the overprice B618 and B818 if you spent your money on outdoor antenna

I bought from taobao or alibaba they are cheaper than shopee even after shipping fees. Shopee sellers stock bought from china too exactly the same thing then resell it to you with RM100+- markup for sure wanna earn.

You want to elaborate?
