Is EPO transparent to 2.4GHz?

[ridgerunner]

Title pretty much sums it up. I'm new to foamies and now have a half dozen or so. I am using FrSky 2.4 GHz and have so far placed all the antennae outside the air frame (separated and @ 90 degrees).

It would be neater/more convenient if I could keep them "indoors", but I'm concerned about attenuation/signal drop through the EPO.

So whats the deal - does EPO block radio waves on 2.4 GHz?

What is your experience with antennae inside a foam structure?

I would not worry about the foam degrading the 2.4Ghz strength. The more important factors are to install the receiver antennas in the proper orientation to provide the best signal strength (many are 90 degrees apart from one another) and its positioning relative to the transmitter antenna(s), as well as keeping the receiver antennas and receiver itself away from radio absorbing or altering materials and objects such as carbon fiber, batteries, ESC's, etc. I have always placed my receiver antennas inside the fuselage and the foam has never given me issues with signal strength, but what has provided issues is if I do not follow the primary aspects mentioned above.

And the 90 degree angular antenna positioning should be in the vertical/horizontal and not horizontal/horizontal.
The reason for this is that the two horizontals provide radial lobes only in the horizontal and thusly any vertical coverage is lost.
T-CAT is spot on about not worrying about the signal strength. To help you understand the technical aspect in layman terms, imagine what the attenuation difference is between metal and that flimsy foam.
It is like a night/day difference. Now the power of these RC transmitters is in the ballpark as your cell phone which is also 2.4GHz device.
Your phone operates inside a wooden house as well as metal vehicles miles from cell towers most of the time so I wouldn't worry one bit about signal strength a quarter mile into foam plane.
Now if you decide to go scale and bling your warbird out in some aluminum skin, now your talking about a completely different technical concern.
The power of these Tx's will reach out farther than human LOS(LineOfSight) capabilities which is where we ALL should be at.

Hi there, I just posted my observations about precisely this subject. I agree that it's not an issue but go and read my new post and figure that one out :]
