No horizontal transponders on SES 1 101

[tiredold]

Hello,
I cannot get 4180 H on SES 1, 101 (or other H transponders)

. I get both polarities on other sats, but not SES1. On verticals I get signal strength of 91, and quality of 72. Even when I swap over to KU, ulta good signal. Just cannot figure it out. Any help would be greatly appreciated. Oh yeah, I put this dish up June 1985.

Nice setup! First off, these channels changed parameters, twice I believe, a short time back. Perhaps a rescan will bring them back as it did for others. Another thing I can think of is a member here was having a similar issue after doing a repair on their dish. Their feed was off center just a tiny amount and it was enough to lose 101w horizontal polarity while still receiving vertical.

Polarity Issue

Have you tried with your actual receiver as of yet, or ONLY with your meter? Also, when using the meter, are you using a NEW piece of coax, ONLY between the meter and lnbf? No switches or anything else? primestar31, Thanks for responding. I will try your suggestion of using another coax...

Thanks, I did several rescans, no luck. I was thinking 5G interference. I will put a spectrum analyzer on it today. But you make a good point, I may be off center. I had that issue with 87. I am too old to go up the ladder anymore, and am bringing home my man lift. The center of the dish is 36' off the ground. Before total loss of horizantals, I had screeching and pixelation and drop out of transponders on this satellite (101) only. That is why I am leaning toward 5G. Asked for a quote for a dual ortho 5g lnb, waiting to hear. Thanks again.

Doesn't sound like a fun job. Good luck and stay safe!

Success at last!!
I got it close, but not perfect. Then I decided to do it properly. I swapped out the lnb for a Titanium 238. Recentered the lnb. Strangely, it would not get measured to centre, but was 2 inches off in the vertical. I measured the true focal distance and changed the coax cables. 91 signal and 74 quality right off the bat!! Never in 40 years has it been this good. I cannot reccomend the Titanium 238 enough.
