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
-
2-3 km maximum
-
Construction in metal. Works good.
-
wing width - 50 mm ---------------------------------------------------------- This one turned out to be better for 1800
-
Result in Metal Does not work well
-
The antenna works, I liked it, you can repeat.
-
LTE 1800 network (1710-1785MHz transmission, 1805-1880MHz reception) The design consists of 2 antennas that operate one for reception, the other for transmission.

Thanks for the antenna. How to take the size of the reflector? And are side walls needed?
-
Yes. Wrong. Noticed only after soldered
-
I would love to do it (if translated to 2100 MHz)
-
And on this antenna you can put 8 patches? Or it will give nothing?
-
It showed a slightly worse result than this antenna: Later I will try to put the dielectric between the plates and remove the bolts.
-
ОК. Thank you. I think I'll post a photo tomorrow
-
I completed the antenna almost. 85% - work done
-
Today completed the antenna. What to say.... The link below is the same and easier to manufacture:
-
I continue to collect them. I like them very much.

I do not know .... Perhaps there are errors in the antenna circuit. I am interested in work. She works. Made 3 people - satisfied
-
Then try
-
Jomy I'm not strong in graphics, but it works perfectly (Base from me for 50 km)

took the sizes for 41...49
