Range

Range optimization

Range is only the result of the wanted signal to noise ratio. Local noise emitters are the most common way to ruin good receiver’s capabilities to pick up weak signals at long range. The system got a transmitter to receiver calculated line of sight range of over 100km. We know at least one customer who actually performed a full flight over 100km out and back. To be able to get the full possible range this system can deliver, you need to be very sure nothing on your plane emit noise in the used frequency band, if it does it will affect the range. This means also it is very easy to detect using range checks.

Range Check

Can be done just like any conventional RC systems and please follow the following steps:

  1.        Unmount the TX antenna and set it to low power.
  2.        Expect 4-10 meters of range.
  3.        Check you have same (short) range with motor on/off and with video cams and video transmitters on/off.
  4.        If no change in the range result, then mount TX antenna again and fly.
  5.        If any unit on your plane affect your range, you are supposed to seek and fix it, if you want to take full advantage of the systems capabilities, or at least obtain a system with best possible signal to noise margin.

Known Limitations

Landscape variations and noise pollution in the flight area is known to shorten the range of any wireless link. Use at least 1/10 of the distance as height. For example at 3 km/1.8mile, distance stays 300 meters/984 feet up, to get full range.

Tx700Pro will provide you with a signal to 100km/62 miles range depending on power selection and on which receiver is used.

Tx700Lite will provide you with a signal to 25 km/15.5 miles range depending on which receiver is used.
