Sadly, the new Lantern will no longer cost $165. Our backers will be getting an OUTSTANDING discount for a really unique satellite terminal. We expect the price of the future version of Lantern to drop to that price, but that is a couple years away. Satcomm is expensive
We will be delivering content between 1525 MHz and 1559 MHz. A simple patch antenna, with gain of about 8 dBi should suffice, but you'll need a specialized (but still free) software demodulator to turn the signal into actual content.
The cubesats will be transmitting around 403 MHz.
The cubesats will have about 8W of power available. It's a 1U satellite, so the only payload is the UHF radio.
Since we want to deliver more than just 10MB of content, we had to switch to a proprietary design, so the connector will not be exposed. But for a software-based receiver, you can add any kind of antenna to, similar to how you work with an RTL dongle.
The RTL can pick up L-band, but it get really hot and unstable above 1 GHz. You should be fine for the receiving the cubesats, though.
