Hi guys, I tried the single wire mod but without any noticeable improvement: with a single wall in between I can't go more than 5 mt or I start getting NACK messages. I'll have to try the dipole or my radio modules are crap (as I always suspected)
Tooooooo short! real range of printed antena modules are around 20 to 30m with one wall at midle.
You should have something doing noise,like router on same freq our other 2.4 ghz device on same frequency.
on my case i live ouside city so my router its the only one on 2.4ghz but never cause me problems .
Its really bad luck all your modules come with problemssome of my modules have and laptop antena instead of pcb antena,but only increase range in +/- 5m though walls
there's one increment that i read here from other member did on amplified version; cover the module with aluminium foil ,and leave antenna outside aluminium,i think that avoid signal propagation before antena do this job.(

I put them on channel 10, that should be away from wifi networks. I leave in the countryside so I don't think I have any other interference. I suspect they are just crappy modules. Hope for the shielded PA to arrive soon (of course all the interesting parts I have ordered are arriving much later than all the other junk :D )

This is very good advice if using the PA version. One of my PA radios was so bad it was actually took down my z-wave network network (yes, z-wave is 900MHz). After wrapping with aluminium foil (and grounding that) it works beautifully.

I am not using the PA version, just a common clone with trace antenna. After rating them 1 star on Amazon, the seller offered a refund in exchange for a change in review.... Sorry but I am only going to add the seller has been kind to offer a refund, but if the modules are junk I can't change my opinion :D

@gohan are you aware that you need to align the antennas if you use a dipole?
I am not sure how to align a pcb antenna with a dipole, but two dipoles need to be aligned so they are in parallel. Otherwise the received signal can have lower strength than when using the pcb antenna.
