- I'm using an RC transmitter and a number of RC receivers in some
- ground-based equipment (an array of lighted targets used to provide a
- good, high-gain handling qualities task for aircraft evaluation). The
- transmitter is in a central location and the receivers are located
- some distance away, all on fairly flat ground.
-
- What is the maximum range I can count on?
-
- I'm interested in varying the size of my target array as a function of
- the aircraft speed. I currently use a projected-diamond-shaped array
- with a length of 319 m and a width of 108 m. The transmitter is on
- the centerline, 119 m from the bottom of the diamond and 200 m from
- the top. The bombing range is quite flat. I have had no problems
- with the more distant receivers not getting the signals, but I'm
- wondering how much larger I can go before I do.
-
- If it matters, I use 220 stepped down to 110 into power supplies to
- power the transmitter card, the receiver cards, and the other
- electronics.
