I’m in the Seattle area. According to Satbeams they predict…
EIRP level = 50 dBW
Recommended dish size = 60cm / 23.6in
Keep in mind the recommended dish size is for receiving a TV signal. The Outernet signal is much narrower bandwidth and sent using a spread-spectrum signal. The signal can be recovered from under the noise using process gain in the receiver.
Your signal will be 6 dB down from mine in the Seattle area. IMHO, you have two options,
- Try it, risk having a terrible signal without a dish, and if it’s not enough signal to lock, get a small dish to help you.
- See how other people do around the country, determine if there’s enough signal and get a later revision of the board. Then you still have to risk errors in this signal prediction software. If it’s not enough signal, you will probably have to get some gain on the receiver with a small dish.
