Thank you jomy on simulation

forget about simulation ,every simulation show optimal or ideal values and don't represent real things.

Some antenna design experts and the spectrum analyzer will not agree with you. There is nothing more to discuss here.

Top 3 Best WiFi Signal Strength Meter Apps

1) NetSpot — both a WiFi signal strength visualizer and a WiFi discovery and analysis tool.

2) WiFi Analyzer — WiFi signal strength meter app for computers running the Windows operating system.

3) Wireshark — is the polar opposite of WiFi Analyzer.

"""" the situation in which the reflector, the vibrator and the first director are isolated....

""" as you can see, there is no great difference...!!!!

The only difference between the presented antennas, is the provision of electrostatic discharge in the case of atmospheric lightning for the antennas without isolating spacers.

In my opinion, isolation process is about the real case and the antenna theory or scientific side of it. And that program you use may don't include that but gives a dBi value according to your design but not examine your logic or logical errors..

I'm a civil engineer and we have this kind of programs, you must know the theoric correct info and only design and its effects on Computer aided programs...

But of course, I don't know the program and this is just a reasoning...

[aurel 22]

I must repeat my question :

Do you have on your wifi card any program which show you signal strength?

So it is very simple to test..in which case is better or larger signal ,with isolation from metal rod or without isolation.

I can bet without  that better reception is with isolation between active plate and metal rod.

please let me know do you can do that test!

Conveniently, the dipole parasitic elements have a node (point of zero RF voltage) at their centre, so they can be attached to a conductive metal support at that point without need of insulation, without disturbing their electrical operation

The driven element is fed at centre so its two halves must be insulated where the boom supports them.

Exactly....and i don't what is mumbo.jumbo simulation talks means

View Signal Strength Percentage of Wireless Network Connections in Command Prompt

1 Open a command prompt.

2 Copy and paste the command below into the command prompt, and press Enter. (see screenshot below)

<<netsh wlan show interfaces>>

3 You will now see the Signal strength percentage of your wireless network connections.
 

The higher the percentage, the stronger the signal strength.

These are my drawings...!!!!

Hello difference between reflectors. In drawings its corner ar 15mm. In video it straight disc. I done couple of this style antennas. But reflector without corner 15mm. If change difference?  And want make yagi antenna it better than this blaster? (Actual question - range)

[Admin 2545]

,,, of course it has importance, the lack of border, it alters the gain, the impedance as well as the front-back ratio of the antenna...!!!

[Anonsas 2]

Ok i we seen this style antenna on sattelite dish. Can Admin make a projection with dish? Before i started to create

[Admin 2545]

,,,for 2100MHz...

,,,this it"s the antenna...

,,,,IMPORTANT...!!! 

,,,at this antenna the power pin of the vibrator has a diameter of 1.737mm and must be made practical...!!!!

 at 4:30 ...

[Admin 2545]

", okay, but I do not understand what you mean with this YouTube ... ???

[Anonsas 2]

Do you think this option is better with dish? How much approx km it can catch signal??

Also want to try "Blaster" with 20 pcs of discs, seperated 22mm. (Tryed standard with 7 pcs as you show) how about signal range , quality? Difference?

Also what modem is better to use to cach internet? Im using cheap chinnese usb adapter (same body different chipset) one ralink other realtek, realtek is much better with chip mt 7601 but maybye in your options is some better modems? Also need to spread internet if it possible to the summerhouse.. 20 , 30 meters.. will add modem photo.

In my option i putting modem straight to pc of course i can spread with wifi hotspot but pc needs to be always on. Maybye can connect straight to router or something what spreads..

What is the working frequency of the base station (BS) that you want to work ... ???

 

[Anonsas 2]

It simple modem in nearest home approx 1 km apart modem supports 2.4 ghz and 5 ghz. But my device only 2.4 ghz. Today i made antenna with 20 discs. 17 x 4cm (between discs 22mm) then 5cm (between discs 12mm) then 68mm (between discs 9mm) and final 9cm (7mm) but with corner about 5 mm looking forward. Maybye do corner to back? Or do straight last disc? Can do projection to see difference with 7 and 20 discs?

[Admin 2545]

For more clarifications see this....

 

[Anonsas 2]

Today will do with little dish (40cm) can you do measurements to will be 2.4 ghz?

[Admin 2545]

Mine it"s 60cm offset outdoor satellite dish TV  and with your dish the gain in the directivity would be smaller(16-18dBi)

Okay, that's better...

 

"you do not watch all the forum...!!

Hello we are using this antenna for our project. Can you please explain all the dimensions and on what basis did you take them??  Also can you explain why is it a Yagi uda antenna?
