Sure, specs says:
- Amplifier Gain: 26 dB +/- 3 dB
- Maximum Noise Figure:≤ 2.5 dB @ +25°C including pre-selector
I still have to search a command to check signal strength.
>For a long term installation, an antenna location that will “see” more sat’s is a really good idea.
Antenna was on the balcony at first floor (european, 2nd floor us) on the balcony, laid there horizontally. Frankly I was not even expecting it to work at all, LOL!
With a ten feet mast I was able to get eight-nine satellites before having to disconnect it.
A little higher and it should have a perfect sky clearance (a little bit more cable will be needed though, hence the question about length).

Hello to all,
I connected the unit to a 11m of H-155 cable(assumed 4.79dB loss "worst
case" at 1.5GHz), thrown the GPS antenna on the balcony horizontally and
this is what I got:
- Given the attenuation (less than 5 dB) do I really need to change the
cable for something better?

Most GPS antennas have an LNA built-in, making cable loss less significant.
Doesn't your antenna have that?
