Re: Rebuilding dipole on a 2.4 GHz grid antenna for 1.7 GHz GOES reception - A few questions:

Would you place the dipole at the same distance (30 cm) as the original 2.4 GHz antenna or move it to the focal distance of 33 cm? Then I still can place the reflector and see if it helps further.

Rebuilding dipole on a 2.4 GHz grid antenna for 1.7 GHz GOES reception - A few questions:

I am trying to optimize reception of GOES 16 satellite. I tried all the tricks I read on the web on how to adapt the usual 2.4 gHz 100cm 24db Grid antenna, like reversing the concavity of the reflector, extending the distance from the dipole by 2.5 cm, flattening the reflector. Af all these only inc...

Experimenting with a Grid Parabolic Antenna for NOAA GOES Reception

I did set up my RTL-SDR with a Sawbird+ and a TP-Link 100x60cm Wifi grid antenna. Regardless of how hard I try, I can't get a Viterbi less than 550. this is sufficient to get some pictures with a clear sky, but the Viterbi goes up when it is cloudy and packets start dropping. The antenna seems to be...
