High Gain $1 antenna possibilities.
The spec for the Ceramic says.
1.575GHz GPS Ceramic Patch RF Antenna 1.573GHz ~ 1.577GHz 3.3dBic
Is 3.3 dBic enough gain? We need with the current patch antenna and LNA a health 9db at the RTL dongle to have enough gain for fade, attenuation, etc.
The advantage of the Helix/helical coiled home made antenna, assuming you can make it bigger. Ie more coils more gain. If we could add enough coils to increase the gain to say 25 db then the poor people would not have to by a a $19 Low Noise Amplifier. So the only thing they would need, in theory, would be a
a $9.00 Chinese RTL 2832U dongle
$1.00 Helical Coiled High Gain Antenna.
