2.4GHz Rx position

Post by Jolly Roger » 10 Jul 2019, 23:19

Doing my first 2.4 install and need help please.

I hear carbon-fibre reduces 2.4 receiver signal strength. I have a largely grp fuselage with some carbon tow around the canopy frame and cloth reinforcement around the retract/wing joiner. How close could the rx be to this c/f without major risk of signal loss? Are we talking 10cm? 20cm?...

Second question: I'm actually using twin X8R receivers (connected via a redundancy bus). Does it make sense to have the rxs in different parts of the fus to reduce risk they are both blocked at the same time e.g. put one on the fus floor towards the nose and one on the fus ceiling above the wing root?

Sorry for these novice questions. :oops:

I wouldn't worry about carbon tows too much Rog - just don't put the last 32mm of the aerials (that's the active bit btw) next to any bits of carbon. Since it's your first 2.4 install I'd also "remind" you to place the active bit of the aerials of each receiver 90 degrees to each other.
It is also a good idea to put the other receiver somewhere else if your fuselage has lots of big bits of carbon in it but in your case I wouldn't worry - just orientate the aerials in a different 90 degrees.

That's really reassuring and helpful Simon, especially about the antenna positioning. I was surprised the Frsky rxs had nothing in their instructions on antenna placement. I guess it's all assumed knowledge now. Anyway, I should be able to keep the antennae at least 10cm from any carbon.

Thanks again.

Roger, I am also a Taranis 2.4 New Member - my Grunau Baby was my first installation. I have thick strips of carbon running down the front section of the fuselage - albeit with big gaps. I recently had the model about 1000 feet up and quite along way out at St Agnes without problems. I DID do a very thorough range check (its buried there in one of the menus) walking all round the model at quite a distance and repeating with model upside down, at odd angles etc. If you do that and all is well... you should be ok I think.
