Hello,

I recently got a DL435-30 from doodle labs...

http://www.doodlelabs.com/products/radio-transceivers/sub-ghz-range/420-450-mhz-dl435-30/


It is an interesting toy that does everything you can do with 802.11 standard but on 420-430 Mhz band... It works with openwrt..

I had worked after reading and following instructions provided by David Bern (W2LNX).

http://www.tapr.org/pdf/DCC2012-Experimenting-...-Wireless-Networking-in-420-MHz-Band-W2LNX.pdf


I used two DL435-30 on both sites with partial line of sight. The two sites were 12 miles away from each other... 

I successfully established a strong link between these two sites.

I used two M2 420 MHZ Yagi antennas..

I'm looking for a bigger antenna more powerful than the yagi for a base station...

Can you guys help with finding the right antenna ?

Thanks

Sorry, I don't have a suggestion for an antenna - but I'm very curious what kind of throughput you're seeing on the connection?

Let's just be mindful of the interference that may be caused with other equipment and operators that use those frequencies. I know I wouldn't be happy if I couldn't make FM satellite contacts (or use repeaters) because someone in the area decided to mesh on 70cm and cover up the signals I was trying to receive.
