BP> - Barry
Most directional links, unless they are panels, border on the legal
limit usually...
24dBi dish + 20dBm cisco (or worst 500mW, 27dBm demarco) = 44dBm,
10m of LMR/CNT400 has 3dBm loss (+1 dBm loss in connectors) and the
more cable you run the more loss on inbound signal you'll receive as
well...
Ideal link = 30dBi dish, 5dBm card with ~-89dBm RX and as short as
possible cable run, will give u the most efficient long range link
possible while still being legal, and least disruptive to others...
It's a public playground and the whole idea is to not be road hogs...
