Hello friends. Buddy got garage and the first thing I brought there was TV. I experimented with carnations for a long time, no sense. I went to visit him and decided to help him solve the existing problem.
Five minutes later, the necessary materials and tools were selected from the existing rubbish.
The main ingredient is ordinary skewers for barbecue (any). We found one.
In our region, the first 10 channels are broadcast at a frequency of 650 MHz, and the second ten at a frequency of 674 MHz. Using a smartphone, we calculate the average frequency and translate it into meters. It turned out 662 MHz using the Internet transferred to meters. The average wavelength in our case was 45cm. Now divide by 4 this figure. it turned out somewhere 113mm. Nothing more needs to be considered. Cooking the skewer. It is necessary to straighten the ring at the end of the skewer. We use any improvised means for these purposes. We get it.
Now bend the square with a side of 110-120mm and get it.
Next, we cut the cable with any improvised means and we clean the ends of the skewer for better contact. Then we fasten using the means at hand (pieces of wire, adhesive tape, electrical tape, thread, etc.) the cable to the skewer we get something like this.
The main thing here is to ensure reliable electrical contact of the cable with the skewer.
Next, we fix the cable on the skewer in the same way with any available means. It happened to us.
Next, connect our antenna to the TV. By the way, there was no connector either, we connected it on wires and made TV settings. This antenna showed excellent results. All 20 channels earned without problems, without lags, and any other problems. After that I repeated only in a more acceptable form (more exact observance of the geometry) a similar design for home kitchen TV. I was also very pleased with the result.
Before repeating, I recommend that you find the DTV broadcast frequencies in your area. They are slightly different everywhere, but I think with the dimensions indicated here and within a radius of 10-15 km. from the transmitting station everything will work fine for you too.
Yes, and most importantly.I ask you to be sympathetic to execution. It was really made of what was at hand at that moment, and the main task (which was solved) was to make the TV work. Something like this.
Thank you for your patience.
