I understand if you don't want to do this but you can cut the pcb trace of the antenna close to the capacitor and instead solder at that place a connecttor (50 Ohms cable connector) and buy or make yourself a cheap ground plane antenne which you hang at a location you like. It will probaly add to your TX/RD signal strenght too.

Btw, this is an omnidirectional antenna
Where is your Aeon Z-stick?
Re: Where is your Aeon Z-stick?
My external USB network hub died. I therefore attached my USB Aeon labs stick directly to the server (groundlevel). Did optimalisation by zseer for a couple of hours. Old problems are back! Bad connections with the top floors.
I'm thinking how to fix this... My options are:
1) Buy a new USB server, which i'm not really fond of. Not very reliable and another 'consumer' in my house.
2) Hack my stick and try to improve reach.
Since a homemade groundplane antenna did 'miracles' for my rfxcom, I really want to do option 2 and see of this improves range.
Ashiarey, thanks for the inspiration. Any extra tips? F.e. What size antenna to build?

Re: Where is your Aeon Z-stick?
Antenna's for 868MHz are small in dimensions. The antenna mentioned in the link above is just 11x22 cm due to the high frequency. Making them larger isn't a option because they are tuned by lenght to this particular frequency. You can do a search on [Ground Plane Antenna calculator] for more information.Phaeton wrote:Ashiarey, thanks for the inspiration. Any extra tips? F.e. What size antenna to build?
If you want to build one yourself with just a few pieces of (220V) copperwire then have a look here http://www.csgnetwork.com/antennagpcalc.html for the dimensions.
