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.

,,and yet where are the dimensions...?
-
,,,and this loop is for 145 MHz...
-
,,,and they are really interesting....
-
This size of wire is not suitable for this frequency.
-
I think it would be best to build the loops from 3x25 mm flat strip."
-
,,,like this../
-
Henry, you really want this antenna...???
-
,,,maybe something like this 144 Mhz Magnetic Loop Antenna...
-
,,,hi buddy...!!! The yagi-loop antenna is too big for this frequency...!!! (the circumference of the vibrator is approximately equal to the wavelength)
-
,,,,other construction details... yagi antenna.pdf siap print driven double U WD CHANEL.pdf driven double U.pdf

I think this connector should also be taken into consideration." sma 5110.cst

S11 or VSWR indicates the amount of energy reflected in the RF circuit and transmitted to the antenna. The smaller the value, the better it is. Generally, S11≤-6dB or VSWR≤3 would indicate acceptable performance.
-
And what...isn't it good...????
-
>>>this might help you somehow...!!!
-
,,,for... dumser2.cst
-
,,,hi buddy...!!! The border has an influence on the directivity of the antenna.
-
,,,and here it's Vika-1.1-800/2700N MIMO-Mesh Collapsible Parabolic Broadband Antenna LTE800/LTE900/LTE1800 / UMTS2100/LTE2100/LTE2300/LTE2600 Powerful 2G/3G/4G/WIFI broadband antenna with high wind resistance and collapsible design. Gain 15-26 dBi. F=790-960/1700-2700 MHz. Ra=50 ohms. Recommended for use with 3G/4G modems and routers over long distances.
-
,,,this is not possible, it's a mistake in the SMA plug (the connection between the plug and the vibrating disc)>>>!!!! ,I will send you the cst file"
-
,,, better try to simulate it yourself...!!!
-
,,,do you like this...??

Types of Polarization: Linear Polarization Circular Polarization Elliptical Polarization

,,can you explain how to use CUDA in CST-Studio...???
-
,,,search here and you will find what interests you...
-
,,,you have the possibility of laser cutting...???
