Loop Antenna

[Admin 2578]

Usually a Loop antenna exhibits a higher gain than a Yagi antenna with the same number of elements

[Admin 2578]

The yagi-loop wireless antenna for wireless has built it in several variants and is remarkable for its low cost of construction, the ease of replication, but also the high gain and stability in operation.
The construction material used  is Cu wire type FY 4mm and FY 6mm, as well as glossy sheet from cans 0.2mm thick cut with 3.5mm strips.
Very good results are obtained with Cu FY 6mm, that is, a diameter of 2.6mm wire that you find at any DIY store

The materials are:
-wire with 6 mm diameter 2.5 mm 1.5 mm
- a cutting tool that does not leave burrs or deform the place of the cut.
-fludor and chlorophonium for bonding
- a relatively high power letcon, because With being massively absorbs strong heat (can not solder with a regular soldering gun)
A triangular fine pile used to create bookmarks on the CU string
- a solid cylinder with a diameter of about 33-35mm
-high quality coaxial cable, preferably H1000, h400, etc. with the necessary connectivity to the user (do not overdo the length of the cable, max 2m)

And a variant of the antenna with flat-band brass...

,,,biloop yagi on PCB  transmission line...

Hi Admin, your yagi loop is very interesting. Could you please convert it to 144.2MHz? For 4 and 5 loop 4mm? Thank you in advance for your help. Henry

[Admin 2578]

,,,hi buddy...!!!

The yagi-loop antenna is too big for this frequency...!!!

(the circumference of the vibrator is approximately equal to the wavelength)

[Henry 1]

Hi, I know, it's for the band HAM. It will be huge compared to wifi, hi. I will send photos after implementation. Thanks Henry

[Admin 2578]

,,,maybe something like this 144 Mhz Magnetic Loop  Antenna...

[Henry 1]

... no magnetic ant, I need max 3-4 el.loop yagi. 10 el. yagi loop:

 

[Admin 2578]

Henry, you really want this antenna...???

 

[Henry 1]

Hi, yes, thanks for the help, please max 3-4 loops.

[Admin 2578]

,,,like this../

 

[Henry 1]

Hi, that's perfect!! Sorry, I forgot, the wire loops have a diameter of 4mm. How would it be for only 3 loops? One last help please.Thank you very much.Henry.

[Admin 2578]

I think it would be best to build the loops from 3x25 mm flat strip."

[Henry 1]

I understand, bigger cross section bigger Q, but I need the ant to be light weight. I can't judge the difference in the parameters of the ants with a 4mm diameter and a 3x25mm strap. I have 4mm Al wire. Please what would be the differences? Thanks.

[Admin 2578]

This size of wire is not suitable for this frequency.

[Henry 1]

OK, please what are the parameters of the ant with 3x 3x25mm tape and 3x 4mm wire? Thank you.

[Admin 2578]

,,,and they are really interesting....

 

[Admin 2578]

,,,and this loop is for 145 MHz...

[Henry 1]

OK, interesting emitter design, ideal for Z setup. Please suggest for you an ideal 3 loop ant with max. G with dimensions with an ignition for both polarizations H+E as used on :

 otherwise I will do the work.

Thank you.

[Admin 2578]

,,and yet where are the dimensions...?

[Admin 2578]

Loop yagis are basically a hybrid design of a tuned loop in a yagi type array. The best material to use for the construction of a loop yagi is brass, or copper. Brass is the better choice since it is easier to solder and corrodes less than copper.

An example of a loopyagi in use. The antenna is on it's side so that the polarisation is vertical.

Hi, thanks for the suggestion, but I really only need a 3loop ant, max 1m long. Thank you.
