Thanks @jlaraujo... Definitely keep us up to date and i'll be happy to order and try it out.

@gohan - I have found both 1.6mm and 1mm on Ebay. Since i like to order 1mm thats what i went with SMA connector but it was way easier to find 1.6mm. I just mean a easy misstake would be to order a 1.6mm SMA connector and 1.0mm pcb. Might probably work.

Since I ordered 1.6mm pcbs, I think I should be fine then.

I really like this design as I am looking for a small for factor RFM69 shield. One question how hard would it be to integrate a connection for a DHT22 to be able to have a small temp and humidity transmitter. I need to have about 5 of these setup in different locations sending temp and humidity back to a gateway.

The sensor will be attached to the arduino, not to the shield

[jlaraujo]

@556duckvader, like @gohan referred, you can attach the DHT22 to the arduino and not to the shield.
You can make a simple PCB that will connect to the required ports for the DHT22 to operate.
If you'd like to have an even smaller footprint, try this design:

It is not yet tested in production, probably will be by the end of the week.

There are also other solutions that have I2C bus pins on the shield and if you are going to make a battery powered node, I'd suggest to use an I2C sensor as it will be much more battery friendly
