Hello All,
I have a 4 antenna UCA pedestrian mobile array antenna inside a backpack, its radius is 10.5 cm.
Despite the small size, it seems to work well enough at 144 MHz band.
At 432 MHz band I would say that only works with very strong signals. You need to be only about 200 metres away to get good bearings.
In some other experiments with human body presence near the array, I also got bad results.
I do not know if the actual cause is the proximity of the human body or any other. Perhaps I did not perform my tests all right.
Please, anyone has some experience with these setups? Could you tell us?
Thank you,
