W3FJW-Ron 0 Posted January 28, 2009 Report Share Posted January 28, 2009 Antennas, antennas, antennas. A better receiving antenna for a video link if that's what you're talking about. A good Tx and RX and noise suppression in the planes equipment & wiring, if that's what you're talking about. Quote Link to post Share on other sites

Any answers will be greatly appreciated Quote Link to post Share on other sites
W3FJW-Ron 0 Posted January 29, 2009 Report Share Posted January 29, 2009 (edited) OK. The RC system. There's not too much that can be done about range except to keep the Rx and Rx antenna away from the other wires in the plane as much as possible to lessen "noise" pickup from the motor and servos which can "desensitize" the Rx resulting in decreased range. Since it's "line of sight" frequencies, you'll probably lose sight of the plane before you lose control unless you're FPVing. For most brands, I have heard 1000 or a bit more meters mentioned for max range (still line of sight) before loss of control. The only antenna that can be modified (if you have the proper measuring equipment) would be the Rx antenna as nothing can (by law) be modified on the Tx. The only alternative would be the Amateur Radio Bands where one can build or modify equipment as wanted for an increase in range.

Terry 5 Posted January 29, 2009 Report Share Posted January 29, 2009 As Ron says, noise from your own plane it the main range killer. I keep the aerial well away from everything, use an opto coupler for the receiver outputs and use a separate battery just to power the receiver. Terry Quote Link to post Share on other sites

Terry 5 Posted January 29, 2009 Report Share Posted January 29, 2009 (edited) Interesting - link to UK supplier? This is the only one I know of http://www.smservices.net/acatalog/Large_Model_Units.html but there are a few circuits on the forums I have seen if you don't mind building one. Mine is built into my UHF receiver so I don't use any of the add on units. Terry Edited January 29, 2009 by Terry Quote Link to post Share on other sites

Terry 5 Posted February 1, 2009 Report Share Posted February 1, 2009 Waht UHF system are you using with the optocouplers? It's my own design based on 458Mhz modules retuned to 459Mhz for UK use only, it's about the only thing that is an advantage in the UK Terry Quote Link to post Share on other sites
