Good day friends!
I have in the village a small TV-sender (analog) half a watt of power running at 490MHz. More than 3 years I transmit a picture of my camera showing how the weather is outside, and some music in the background all OK but I have a range of only 400 meters. I would at least 800-900 meters!
I want to make a better antenna, however, because of all that I tried some of them probably did not made exactly the best that I knew ... - - So I asked you if you want to help me to understand because, after all, about antennas, signals ... but to me it is a wish already long but just can not make it ... I do not know the precise dimensions of 490MHz.
A little problem is that my house is in the middle of the village should send a signal (in all directions OMNI) Horizontal polarization because all the TV antennas are horizontal.
If you can vertical polarization, made to a GP (Ground Plane) or J-Pole ... but you probably can not. Changing the polarity is losing a lot!
- Which dish do best?
From TV-sender to Antenna 5 meters by cable (H1000) 50ohm!
- Is this good? Dipoles turn 90 degrees, or what do you think, maybe another dish to do to be a good and precise at 490MHz ???
THANK YOU !
