This knowledge is very important to me. Thanks Mr. Andrew.

Love the video how 2 but would like schematic showing your numbers and maybe turn it into a small beam antenna i have built some yagis, poles, and inverted v antennas but they were 2 meters and 70 cm frequencies

It is always with interest that I watch for years your instructive and very educational videos. I have a question about the possibility of using WIFI frequency to repatriate water height data in a well to a receiver at the head of this well. The well is 100m deep, circular in section and 450mm in diameter. I would like your opinion on this possibility of this process. I couldn't find a formula for wave propagation and attenuation in a long tube connected to earth. Thanks.

Great work sir

The measurements of the coil are not clear to me, so the wire is 1,5 mm in diameter so about the same as a 2,5mm square electrical wire. But the diameter of the coil is that the inner or outer diameter??

Great videos !! Please Share some ideas to make a feeder for parabolic antenna !!

is the gain of this superior to the standard aerial?

??????? When are u going to build a direction antenna for 4G and LTE combined covering 700Mhz as well now that AU has stripped it from the TV bands and allocated it to mobile wireless services. Hopefully hi-gain enough for a 16km distance.

Antenna that u have, it is from which model of tplink? Is it dual band antenna?

I wish i could buy a well designed antenna like this somewhere.

It's nice showing how to make the antennas but what about the mathematics behind it i.e. Lander over frequency and getting the Measurements for quarter wave half way and 3/4 wave.

Hi, I'm designing a computer case and want to integrate a Wifi Antenna, after trying several comercial antennas I made a Biquad based on your video and it is by far the best, 5 bars all the time, would you recommend a different design? I think I prefer directional antenna, I can make it so users can re-orient it to face their router, am i right in thinking this will perform better then any omni design?

Can be made with a coaxial tv cable?

Last time i asked what's more important width or length ? I got a slap lol

Remember, in life you have three choices when it comes to the internet connection.

Seems like an AI supercomputer could run billions of design iterations to come up with the most effective dual band antenna size and shape.
