We made a few active ceramic antennas that had the RTLSDR integrated onto the back of the ground plane. These are a steal at just $25. We only made a few dozen of these for testing. Only 16 left in inventory.

Hi Syed
Is the rtlsdr specific to the L band ?
Kind regards
Graeme
Since the RTLSDR is hardwired to the antenna, yes, it is specific to L-band. It is the SAW filter and antenna which prevent reception of anything outside of L band.
I also have one of these! It works! $25 is a steal!
Hi Syed
That’s excellent news.
I ordered 2 x units earlier on today.
Glad to hear from thomslik that they work well too,thank you.
Kind regards
Graeme
got one for my self 
I ordered one of these just to get a taste of what this is all about. What would be the recommended software to pair with it these days? I could do windows, *nix, or pi for hardware.
I figured if I like what I copy I could upgrade to the Dreamcatcher platform.
To receive Outernet, these easiest thing is to use Outernet in a Box.
Of course, it’s just an RTL-SDR, and there are numerous tutorials for receiving various Inmarsat signals.

Perfect. Can’t wait to get started.
Is there anything special that I need to do to get this working with the CHIP, or is it just plug and play?
I am flashing skylark on it now.
Should just work; always has for me 
The revised outernet homepage www.outernet.is looks nice, good job
I add this because I now see all the clearance rtlsdr’s are now sold-out!
Those moved out pretty quickly. Glad to see them finding new homes.
Can we get some specs/info on these? Jumper usage, why I can’t see it with rtl_eeprom, txco specs, test point descriptions… Just got mine.
Thanks.
Works very well, it is quite sensitive though. I was hoping to use it with a 3d case I printed and it seems to pickup interference from the CHIP board. Once I moved it about a foot away, it began receiving 10+ db, better than the patch antenna. I guess I need to try the same thing with the patch antenna now, possibly print out a case similar to the lantern alphas.
