Receiving GB3EN

GB3EN is designed to be received on a cheap satellite receiver.

This receiver works down to symbol rates as low a 1MS/s and decodes H265 as well.

Also, you will need an aerial

If you don’t have a horizontal 23cm aerial then its quite easy to make one. If you make this design really accurately it should have a gain of 16db

If not made so well, then its gain is still about 10db. Connect it to the RX with some satellite coax.

Here is how to make a 23cm panel antenna

You may need a preamp as well, it depends on how far away from GB3EN you are.
