Great explanation! Thank you for this video!
🇺🇲
🇺🇲
this channel is really good I am impressed, currently studying for my new role
thx!
👍🙏
Thank you ! Absolutely obvious 😊
You're very good
did u mean that omnidrectional antennas' polarization depends on their orientation? for directional antennas, it depends on their geometry more than their orientation... like w whip antenna is a monopole (omni) and its polarization depends on its orientation. This topic has bee confusing to me, I thought I understood it but now I am more confused after hearing u say the opposite.... please explain.
where can i get your full course please , thank you
Than You
great
Wow that was really pleasant to listen too, and I learned a lot. Good teacher! Subbed.
Excellent video !
Very clear. Thank you 👍
excellent video
Does this also affect or apply to GMRS or ham frequencies, or just the much higher ones like Wi-Fi?
Excellent video! Thank you!
tnx ur clear explanation gl
Thank you so much for this course, it was very helpful introduction/explanation on signal tx/Rx Especially the explanation of dB calculations I only wish you did additional course on the more advanced stuff(which I dont know what is at the moment :) )
Sir, you are so amazing, you can teach this 100x better than my professor for this course.
Comment aranger dbm sur cellulaire svp
he is god of number
your two is so cute
i love you
Does this formula only work for milliwatts? Or can I use watts?
Thank you for doing this. Very helpful.
Clear explanation 👌 شكرا
Great video, thanks
Thanks so much for clarifying this. I install tv antennas with my dad and we use a signal strength meter to help dial in the direction we need to point the antenna to get the best signal. I've wondered for a while why the DBm is always a negative value and now it makes sense
Spelling of received and strength are wrong :P
He seems nervous but it’s all good
Thank you so much for this!
Great explanation lots to learn. Thanks.
what a pleasure, someone who spells like me, knows what your doing and gets on with the job. had the same experiance at IS in south africa, genius chaps, couldnt spell to save their life, made me concentrate on the job and not what people thought about my spelling. thank you kind sir

-96dbm equal to mw?
This man's analogies and explanations are great and he's humble.
We need one of your brilliant videos to be on MU-MIMO
Tell me about Signal
English please
Thank you sir A very good explanation your videos are a great help for all students.
Thanks for this ❤️
Sir, this is the best RF math course I found on Internet. Thank you very much for the knowledge
studying for my ccnp enterprise and this video/series is amazing - thanks for creating.
I'm in the same boat. Found it really useful after reading the content in the book
very good explanations in this course, thank you very much.
After so many videos! Finally! Someone who made me say; "I see it now" This is nuts! Thank you sir! Really appreciate this video!
This is 100% how I feel as well 😂. Great videos!
9:31 Where is it illegal to build your own antenna???
thanks for the explanation. now i know -60dbm is actually 0.000001mW
an equation would be nice
Is the best 5 minutes of my life
