Re: Aircard yagi antenna help needed

Thats because the antenna is NOT really 24Db of gain and.....
15 feet of RG-58 Coax will lose more signal than the antenna
gains!!!
RG-58 is a sponge at 880Mhz..and even worse at 1900MHZ.

RG58 typically averages 10db per 100 feet loss at 900 MHZ, less at 800. At
15 feet loss would be about .6 db. I work with this stuff every day. My
guess is that a connector is defective, the cable is bad or the card has a
problem. Did he put on his own connectors?

Please back up your "fact" that "15 feet of RG-58 Coax will lose more signal
than the antenna gains!!!"

Thanks for the quick reply. That makes perfect sense, I did not
realize RG-58 had that much loss. I have been reading that LMR-400
has a much lower loss, so I will be trying some of that soon.

Thanks again,
