Nooelec GOES Weather Satellite Mesh Antenna - 21dBi Parabolic Antenna w/ 1.7GHz Center Frequency, 200MHz+ Bandwidth, LMR400 Feed Cable with Male SMA Connector, Mounting Hardware, & 2 Year Warranty

Peut-être que j'ai eu un coup de malchance avec mon produit, comme le mentionnent les avis. Je suis un opérateur radioamateur et ce n'est pas ma première transaction avec Nooelec pour des produits de LOISIRS. En général, c'est assez précis et les informations fournies reflètent fidèlement la réalité, mais ce qui est surtout important, c'est que les produits sont constants. Concernant l'antenne, je vais tout de même demeurer concis dans mes commentaires. Si vous êtes novice, envisagez peut-être de devoir acquérir des vises plus longues ou de travaille un peu le métal de l'antenne afin que les vises passent à travers les trois structures au niveau du beam central. Cependant, elle présente une belle apparence et fonctionne correctement sur les signaux des divers satellites après 45 à 60 minutes de mise en position.

The antenna came with an undocumented bonus! The dish to pipe system has been upgraded. Included is a mount (see PIX) that allows the elevation and azimuth to be adjusted while the dish is firmly secured to the vertical pipe. The original 'L' plate is included, marked "Alternate Mounting Bracket". The new system is FAR superior: After locking the dish down on the pipe, the azmiuth and elevation are easily tweaked. Once in position, two nuts are tightened and done. This new mount is not mentioned anywhere in the documentation - it is attached to the dish exactly as the original 'L' bracket would have been... There are issues with the original 'L' bracket, with the elevation slot. The clamp holding the entire dish assembly must be loose to adjust AZ/EL, while keeping the clamp stable. Adjusting one causes the other to slip and a third arm is really helpful. I know this for fact, as I have another 2' solid dish using the exact same 'L' bracket. The new AZ/EL mount alone makes the price of this dish acceptable. OK, in conjunction with the NooElec SAW+GOES filter/amplifier driving 20' of double shielded RG-55 cable (53 Ohms), the dish performs fine, in a snowstorm here. The SDR here is the RSP1a by SDRPlay, and SATdump software is used for decoding the images. The SAW filter and amp must be mounted at the pigtail lead from the dish. Any additional cable between the dish and SAW WILL degrade overall performance. My SAW is powered by an external bias-tee between the SDR and cable end in the shack, as the RSP1a lacks sufficient current capability on it's bias-tee. Note that the NooElec SAW+Goes is NOT waterproof. As can be just seen in the PIX, I used a 5" long pill bottle, with a hole drilled in the top to just accept the pigtail lead. After connecting the pigtail and output coax, the SAW slides up into the bottle, and coax seal waterproofs the top of the assembly. That said, as others have indicated, the overall quality of the dish is marginal to poor. Fit and finish is rough. There are sharp, unfinished edges between the dish mesh sectors that can cut skin. I gave a 5-Star rating due to the inclusion of the superior AZ/EL mounting system. Big PLUS. I installed this rig during a snowfall...note the mount PIX. The mount has two bushings at 90 degrees from each other, with a long 10mm bolt. When loose, the azmiuth and elevation are easily adjusted - there are detents on the mount to make positioning easier. Once set, simply tighten the two bolts ... no messing with the mount to pipe brackets. I may be wrong, but NooElec does not manufacture this kit. The antenna boom assemble has Chinese labeling, and no pains were taken on the dish fit and finish. Have Fun! UPDATE after several days of perfect reception: Observing the picture of the mount, note the coax pigtail exiting the feed antenna boom. It is impeding the elevation - it is just about maxed out at 39 degrees due to the pigtail. Simply reversing (rotate 180 degrees) the dish on the mount places the pigtail BELOW the elevation adjust, allowing full 90 degrees of EL if desired. This new mount is lights out good!

Awesome antenna and easy set-up 💯👍🇦🇺

It's amazing to me how easy it was to get signals from GOES 19 using this antenna. I had been trying to use an old DirectTV satellite dish, which is about the same size, with a homebrew feed; but I kept having difficulty pointing it because of the offset feed angle. It was also very bulky/heavy. The Nooelect grid parabolic is light-weight, and the axial feed makes it easy to point! You still need to be within a couple of degrees, but it's a lot easier to figure out where to point. And the feed is of course professionally designed and sized to be efficient and at the correct focal point. It took maybe 30 minutes to assemble the antenna. But once I got it outside, I had it up and receiving GOES 19 using an RTL-SDR.com dongle, Nooelec SawBird+ LNA, and SatDump within about 5 minutes. The savings in time and stress (for what is intended as a portable setup - which means aiming fast is important) with this antenna make it well worth the cost. I do wish that it shipped with printed assembly instructions, but it was pretty easy to figure out where the bolts are supposed to go after looking at the parts for a couple of minutes. Tip: if you need to adjust the elevation by a few degrees between "clicks" / detents on the mount, you can use a zip tie or two, tied between the grid antenna and the mount, to hold it in place at exactly the right angle. Probably not necessary for GOES to be that precise in elevation angle, but it does give you a little more control.

While it's only a dipole, which means you take a 3dB (half power) hit on a RHCP signal, it still works phenomenally well for GOES. Mine is on a AZ/EL tracking system, so I t also works phenomenally on HRT signals from NOAA and meteor. You HAVE to use the SAWBIRD filter with this antenna for GOES, and it HAS TO be right at the antenna - not 10' away. other than that, works great, and the price point was decent too.
