Re: HRIT and LRIT Low-Cost System

Rob, The "right side being lower" is referring to the position of the feed element, not the primary reflector. The polarization angle plus skew angle should look like this for GOES 16. Even though the specified polarization for GOES 16 is vertical, a diagonal position has been found to wor...

Re: HRIT and LRIT Low-Cost System

It appears that supply vs demand (or possibly a new tariff) has increased the price on all major components originally listed in this article, since it was first posted. Perhaps as others find new low-cost solutions, these will be posted here. If you come across alternative viable antenna solutions,...

Re: HRIT and LRIT Low-Cost System

The frequency of operation for GOES 15 LRIT is 1.691GHz and the frequency of operation for GOES 16 and 17 HRIT is 1.6941 GHz. The modification described in this post is only for the Premiertek ANT-GRID-24DBI antenna so that it will operate better in the target frequency range of 1.69 GHz rather than...

Re: HRIT and LRIT Low-Cost System

Rob, Some additional information for you to consider. The grid antenna choice was made for this post with careful research and a considerable amount of effort went into testing, modification, and seeing what worked well. The 1 meter diameter grid parabolic antennas, regardless of brand, typically em...

Re: HRIT and LRIT Low-Cost System

The point of this post is "low cost." An earlier post was provided that describes a Yagi Loop antenna that performs better and is for operation at 1.69 GHz. Refer to viewtopic.php?f=5&t=2674
