[HSMM-COS] Antennas

Hi Everyone,

19dbm (max output of the routers) is about 76 milliwatts of power.

Better luck on ebay ($45, free shipping):

 Of course, you'll now need a weatherproof box to mount the hardware in
so that your coax line is < 3ft (shorter if possible) due to the high
losses incurred at 2.4GHz.   You may also want to run an Ethernet line
up, and if you do, you'll want POE (power over Ethernet) to the router. 
If the Ethernet line is > 100 feet or so, you'll need a large capacitor
to mitigate power fluctuations due to resistive line losses as the
router transmits.   Don't forget the watertight seals for the connectors
and the lightning/surge suppressors.

 I use times microwave LMR-400, or better:

As with many things, the router turns out to be the "cheap" part..
