Re: Mode-S Antennas



Steve -

The key difference are the 2.4 Ghz antennas that are used for the 802.11
network
RF units for routers/bridges, etc.

The link you left  www.hyperlinktech.com , describes "proprietary
connectors" in its
technical specifications for the dish.  Remember that 802.11 is a transmit /
receive usage for the dish

MMDS is a receive only antenna and most of these have a standard N
connector.

Why the difference??  As Jon pointed out, the FCC would like to prevent
transmission at 2.4 GHz
with high gain antennas AND amplifiers.  "thou shall not microwave your
neighbor"
