Re: [Gumstix-users] GPS antenna

[Alexi G. <al...@wp...>]

The one without the housing absolutely does NOT work. I did not order the
antenna for the particular Sparkfun Lassen IQ sold by Sparkfun as was
suggested.

I first received the antenna without the housing, which had an SMA
connector.

It did not work at all. Absolutely no NMEA messages. After receiving the
antenna with the housing I got NMEA messages while indoors immediately.

They both have an LNA. Sparkfun advertises the one without housing as
a 3.3VLNA, but the datasheet they provide suggests 5V.

Whatever the case, it may work under very favorable conditions, but I
wouldn't count on it.

I wish the cable on the other one was shorter.
