Nicely explained
another great work, but the signal is reflecting off of the biblical Firmament.. said to be "a Vaulted Dome" "as a Molten Looking-glass". What would reflect better.. a solid crystalline dome.. or a highly charged field which would only absorb the signal ? the first one obviously
please include effect of earths magnetic field
Plz make video on ionospheric layers
good expalanation
Your positive comments motivates me, Thanks and welcome 🙏

Why the number of atoms are less when we go upward direction. In reality the maximum ionization is taking place at the topmost layer and it decreases with decreasing height
sir explain types of ionospheric layers
Sorry... But the electron density is high in upper layer mean F layer
You are right
Super mawa

Tq sir but I posted a question on microstrip antenna but U did not replied me till date
And I cannot get notes to this
I am unable to find notes to this on ur website
See the answer
If signal freq range less than 2mhz signal not be reflected then what will done
Please tell us about the sporidic E layer and critial frequency.
Critical frequency is already uploaded in awp playlist
Nice,tq sir
Thanks and welcome
2x speed also seems to be slow🚶♀️🚶♀️
Does the sky wave refract or it reflects
Sir, how to check whether chemtrail is processed on our ionosphere? what is d punishment for other countries for secret establishment of haarp and chemtrail on our ionosphere???
Hello Sir
SSC IMD exam me maximum ionisation density poocha tha kis layer ...
Mene F1 layer answer Kiya
Wrong ho gaya..
Ionization density will be more at F2.
Cosmic rays density is more at F2 then F1 and I have already explained cosmic rays does Ionization. So according my explanation IMD exam answer key is correct.
👍👍
Sir can you make an video on refractive index of ionosphre
(very good) ke power 100 sir
derivatives bhi bta dijiye sir
sir is tropospheric propogation is duct propogation???
That means according to polarization of view
Tq sir
Sir please do add subtitle as have hearing problem . I some time get different pronuciation & miss some words
It is very difficult job. It takes lots of time.
Sir please explain optimum working frequency

Sir ,Your website is not working
My assistant is on leave, her grandmother is expired so she will join after 15 days. But I can help you to have those materials of this videos
Sir please Help me 😊
Sir wave propagation topic me koi derivation to nhi hai na
Go through lectures, it is more based on fundamentals.
Sir if freq. Is high wavelength is also high right. Then why the wavelength goes low travelling from srilanka to others high freq. To travel
Nope
If frequency f = c / (wavelength).
So if frequency is higher then wavelength goes low.
@@EngineeringFunda ohh yes sir, I realized thank you for the reply!!
How to measure ex 2 to MHz 15 & 30
Mechanism for sky wave propagation we want sir
Plz check your grammar..its killing my interest..anyways it was useful
Please sir ,VLSI design ki bi videos banao
Dear vikrant , I am not the right person for it. Sorry for that
It's okk ,Thank you sir for antenna videos
Sir teach us reconfigurable antenna
What is wave tilt in ground wave propagation
It is tilt of EM wave due to magnetization of Earth
More Ionization take place in top most layer
Please provide multihop propagation
what happens if high frequency more than 30mhz is passed??? will it disturb ionisation???
It will penetrate through ionosphere
Sir how can I get antenna wave propagation PDFs sir
You can download it from my android application engineering funda
bro na 12th but engineering subject la vathuchi
English Subtitle Please😁
Srilanka spelling is incorrect
sky wave propagation frequency 2MHz to 20MHz....ur u wrong
It is 3 to 30MHz dear
It is 3 to 30 Mhz
are yr Hindi samjhate to jyada chalata
Bro tooo many ads in between. Plz take care of that
This is Diwali season that's why. Else it doesn't show that many adds
@siva prasanth hey I am gone guy is back.
bro youtube premium NO ADS at all.
Ads help the creator. Please see them all, it will pay some to the creator.
All we can do this free education providers is just watching adds ....they earn money from us watching adds so don't complain
so slow
