6 Еlement loop antenna

[sa3500 21]

The antenna design is shown in the figure, dimensions - in the table. For manufacturing, you can use a wire made of copper or brass with a diameter of 3 ... 5 mm. The wire is successively bent according to the shape shown in the figure, the joints are soldered. For greater structural strength before soldering joints can be tied down with thin copper wire.

Antenna cable is soldered at points "A" and "B". At point “C”, the cable sheath is connected to the antenna material.

The antenna showed good results

,,, the excellent realization ...!!1

,,,on which channels did you built this antenna...???

[sa3500 21]

took the sizes for 41...49

[Admin 2545]

,,, if you want, I can make a simulation for this antenna ... !!!

[sa3500 21]

Jomy I'm not strong in graphics, but it works perfectly

(Base from me for 50 km)

[Admin 2545]

,,, it does not matter, I would like to know the gain of the antenna ... !!!

[sa3500 21]

Then try

[Admin 2545]

,,, it can also be done ...

 

[Admin 2545]

,,,for your antenna about these are the results ... ???
,,, the frequency band does not match and the impedance is not good...!!!

,,,also, the gain in directivity is small...!!!

[sa3500 21]

I do not know .... Perhaps there are errors in the antenna circuit.
I am interested in work. She works. Made 3 people - satisfied

,,, which TV channels are you working on...!!!

,,, simulation of specific program antennas can never fail...!!!

 Ukraine, base in Kharkov

distance to the base 50-60 km

 

554 МГц | channel number 31
channels: Интер, ТРК «Украина», 1+1, НТН, К1, Первый Национальный, ICTV, Enter-Фильм

Частота 586 МГц | channel number 35
channels: Zoom, Киноточка, СТБ, ТЕТ, К2, Новый канал, М1, 5-Канал

Частота 690 МГц | channel number 48
channels: Mega, Pixel, XSport, НЛО-ТВ, 2+2, Dobro, Tonis, BUSINESS

Частота 770 МГц | channel number 54
channels: Винтаж, Эскулап ТБ, ОТБ, Новый формат, Тонис-центр

I accept everything. 

770 MHz - slightly weaker than the rest

",,,anyway the dimensions of your antenna (ch41-ch49) are not suitable for your Tv channels...!!!

,,, why do not you want to try a kind of this antenna ... ??

(Official document of the Kharkiv region)
Below is a list of existing digital television channels for our region as of July 2014.

[Admin 2545]

,,,, anyway, your antenna is not really good ... !!!!

,,,so it must look like a true quad antenna with 11dBi...!!!

[Admin 2545]

,, our friend sa3500, built this fake antenna...
 

 

I recommend this broadband antenna...

Is this antenna allows for 4G LTE 900 MHz network

,,,yes ,it is for 650---950 MHz...!!!

[Ingsun 2]

In the area I was hard to find coaxial 50 ohm, can this in replace coalial 75 ohm

,,,,yes, of course, but some dimensions have to be modified...!!!!

,,,, and I think you're right, a 75 ohm coaxial cable should be used and I think I'll make a simulation for this impedance ...!!!

[Ingsun 2]

Thanks admin, I wait for his simulation

HI mate. Do you have this model in CST? It is awesome! I would like to try to make it with Circular Pol. Thanks

[PeBac 2]

Hi

Would it be possible to get a CST-file of this antenna. Thanks

[Admin 2545]

,,,hi buddy...!!!

I don't think I have this file anymore, but I will resume the simulation, if you want...!!!

[PeBac 2]

Hi

This would be fine. Can you even adjust it for more gain?
