horizontal but no vertical?
ADVERTS 1
Helped a guy out today with his Glorystar system. Could not get G25.. but pretty sure it's a bad lnb. I took the other one for AMC4 and switched them and it showed G25, although pretty weak. Anyway, I switched them back and tweaked AMC4 as high as I could. On his Fortec Mercury Star he was receiving a signal on most station of anywhere in the 70-80 range. All the Horizontal TP's were fine. I couldn't get any of the Vertical Tp's to show up. Pretty sure it wasn't the receiver, because even with my birddog meter hooked to the bullet LNB I was peaking the Horizontal tp's fine, but barely registering the Vertical tp's.
Do I need to change a setting on the receiver? Or is the LNB bad. Like I said, even the birddog barely read anything on the vertical side. Or is there a setting I am missing for aiming. I should think if the H-tp's are good, then the V ones should be as well?
Also, any good sites for figuring the settings of a dual lnb system for G25 and AMC4? Zip is 65803.
I can find the settings for each sat, but not for the combination of two.
Thanks all

Were you receiving H and V on one LNBF, but on the 2nd LNBF only receiving H? Did the problem switch to the other satellite V channels when it was swapped? You probably noticed that most channels on AMC4 are horizontal, but many of the channels on Galaxy19 (Galaxy 15) are vertical. It is possible that an LNBF has a bad polarity, but it is very rare as the factory prequalifies the GEOSATpro SL1 stock to grade A rating. The customer may choose to send the LNBF in for testing. If it is faulty and within the one year warranty we will replace and return ship at no charge.
Do not change any settings in the menus. These are preset in the firmware.
There are not separate LNBF settings for each LNBF. One setting of the bracket rotation (skew) and a slight adjustment of each LNBF after the signals are peaked to optimize each satellite. It is possible that the LNBFs were being set to the LNBF rotation (SKEW) instead of only rotating the dual bracket?
Aiming coordinates are shipped with the system. If you wish to recalculate the LNBF setting use:

No, I was only getting H on one LNBF, and unable to pick up any V of that same LNB. The other LNBF was dead, I couldn't pick up anything with it even when I knew that I had signal.
I'm not really sure what you mean about setting the LNBF's to the rotation instead of rotating the dual bracket?? I know the dual bracket has the settings on it and it rotates... which is what I set, but it was pretty close when I got there anyway and didn't need much changing. I checked geosatfinder before I went to help him, and 101 said skew should be +10 and for 99 it should be +7.4 so I figured somewhere between the two should be close.

The chance of having one bad LNBF is rare, but exists. The chance of having two is pretty much non-existent. I would suggest reviewing the process in the Installation Guide.
Is the receiver activated with code 2020? Was the dish checked for warping or clam shelling? Is the face of the LNBFs slid 3/4" towards the reflector? IS the receiver or the meter being connected directly to the LNBFs or through the switch?
DO NOT rotate the individual LNBF (SKEW). Only set the skew on the dual bracket.
- Connect the receiver directly to LNBF #1 (on the right side when standing in front of the dish) and place the receiver on 3ABN. Find and peak.
- Connect the receiver directly to LNBF #2 (on the left side when standing in front of the dish) and place the receiver on TBN. Bump the dish left/right /up/down to peak.
- Place the receiver on The Word Network. Peak for weaker signal.
- Power off the master poawer switch or unplug.
- insert the DiSEqC or 22KHz switch
- Repower the receiver.
- Place the receiver on The Word Network. Fine tune LNBF #2 rotation and front to back to peak signal quality.
- Place the receiver on Gospel Music Television Network. Fine tune LNBF #1 rotation and front to back to peak signal quality.

Thank you for being so helpful! Don't know when I'll get out there again, but I WILL get him going. Like I said... currently AMC4 is coming in great on all the H transponders, but I'm not getting anything on the V either with the birddog or at the receiver. I'm a bit thrown off there.

Every time my dish went warped, because of the wind, I would first lose one polarity on one lnb and then most everything on the other LNB. So I would definitely string check for warp. In the cold weather and snow that I lost TBN mix on G19 and most of AMC4. I climbed the ladder to look at the dish and there did not seem to be any snow on the lnbs and very little if any on the dish. When the sun came out for a few minutes suddenly, the signals came back. I do not know if there was ice or a cold warp on the dish, but I got most signals back.

Is there a known history of this antenna warping in the wind ?

The dish has no issues with standard winds, but rv1pop lives in an area that gets hit with incredibly strong and consistent winds. He recently posted that a 120mph + gust took out a wall that supports some of his dishes recently! He owned one of the original dishes without the LNBF side support arms. Updating his dish to add the side support arms has helped in his battle with the extreme winds.
