winchweight Posted June 26, 2008 Share Posted June 26, 2008 1. Do the antennas have to be straight?2. Did I read somewhere that they are prone to breaking where they enter the rx box? Quote Link to comment Share on other sites More sharing options...
YakMad Posted June 26, 2008 Share Posted June 26, 2008 Which rx's are you using? I think you went with Spectrum, did'nt you? if so and you'er using the 6200 or 7000 or higher spec rx the easy solution is to put a a piece of heat shrink over the antenna wire and the plastic moulded tube it exits thru, it's worked well for me, I think Timbo has posted pictures of his similar mod.

winchweight Posted June 26, 2008 Author Share Posted June 26, 2008 Yep, sorry I should have said. I have gone Spektrum and so far have a AR6100, and an AR9100(?).Do they have to remain straight as well, or can I bend them in a bit to fit inside a compartment?

Lee Burke Posted June 26, 2008 Share Posted June 26, 2008 Eric, if the 2,4Ghz antenna are inside the shell of a foam model will they pick up the signal equaly well? They seem to - but . . . Quote Link to comment Share on other sites More sharing options...
YakMad Posted June 26, 2008 Share Posted June 26, 2008 AR6100 should be fine as I persume you will only be using this in ep models with very low vibration, you could put a blob of silicone were the wires exit the case, I have had to bend the wire slightly on an AR7000 installation with no adverse range problems, just keep the main rx and the satellite rx as far apart as possible (2 inch is recommended at least).

Lee Burke Posted June 26, 2008 Share Posted June 26, 2008 Whoops, Shaun, my earlier post is a bit of a thread hyjack Sorry about that. Just seemed to follow naturally on your question about the antenna wires which interested me too, but a bit of a no-no. Quote Link to comment Share on other sites More sharing options...

Tim Mackey Posted June 27, 2008 Share Posted June 27, 2008 Eric Bray wrote (see)I've got the Futaba, but I think the same rules apply here. The antenna wires are supposed to be set at 90' to each other, (ie in an L shape with the box in the middle). Try to have one pointing upwards, with the model in its normal upright orientation, and the other pointing towards the tail feathers, unless you have used carbon or wire bowdens or pushrods, in which case try to get the horizontal antenna wire at 90' to them as well, ie sticking out sideways.A small curve in the wire is ok, but don't put a sharp bend in halfway along one wire. It won't hurt the wire, providing you don't keep bending and rebending it, but it will play havoc with the received signal 'pattern'. See my previous explanation of radio waves, in another thread, for a fuller understanding. Well no actually. The spekky "single receiver units" such as the AR6100 have wires exiting from either side of the case and they remain so - not at 90 degree to one another. With the twin rcvr units ( AR7000 etc ) again, leave the aerials straight, but mount one unit with the aerial at 90 degree.The picture above just about shows the location of the main and satellite receivers - main has aerial "across" the fuselage, and the satellite can just be seen stuck to the side of the fus therefore presenting the aerials at 90' to the main. thread Here.

winchweight Posted June 27, 2008 Author Share Posted June 27, 2008 Thanks for all the responses. I'll be test flying my installation in my foamy hawk this weekend, weather permitting. Quote Link to comment Share on other sites More sharing options...
