[MLB-WIRELESS] Satellite dish..

[Matt Pearce]

*smirks* I think you might go over the EIRP a little there, although more
testing would be required to double check this ;-)

Although on the plus side, you are going to have one extremely narrow beam
width on that so the chance of anyone tapping in and finding your link are
going to be fairly small, however a 3.8km antenna is not going to be an easy
thing to hide on the side of your house !!

Matt.
