I am planning to combine rf output two antennas electrically, and feed the combined output to a single receiver (dvb-t). In this experiment, I am planning to use randomly different lengths of two coax (as opposed to exacly equal lengths shown in diagram I posted), and try to achieve phasing by trimming one of the coax bit by bit.
If this experiment succeeds, I will post the results.
as obj pointed out, timing is your enemy. Unless there is some combination of software that can effectively merge or discard timestamps from disparate receivers, then you are fcack…
A solution to combining 2 antennas into 1 reciever,or 1 antennas into 2 recievers, as I have successfully done ,can be acheived like this. I will attach a photo, all points terminate as 50 ohms. You will need 50 ohm and 75 ohm cable and soldering iron.
The 2 bits of 75 ohm are a 1/4 of a wave length long but multiplied by .66 from the web 75 ohm coax cable segments have a V.P. of 66%. At this point, multiply the V.P. (.66)
