[MLB-WIRELESS] $330 Aus 15.4dB Omni. Anyone interested ?

[Matt Pearce]

You are far better to work on an efficient system that uses what power you
have rather than flooding the spectrum with excess power.  Another
unfortunate side of RX/TX amps is that they ampify noise as well as signal,
with this in mind you should keep coax runs down to a minimum cause that
introduces loss, and try and use the best cable you can.  Basically you want
to build it more like a butterfly than a bull.  And with the correct
antenna's, cable and bits you can get very good results from standard cards
without amps.

Matt.
