Some new guy Q's

[hex13]

I live in the Philippines and I bought a dish set to to view FTA indian channels. My problem is at night I lose half of the channels and during the morning everything is fine. What could be causing the problem?

As for the dish whats the recommended LNB for best results?


I hope I'm in the right forum for this.

It would help to know what size and type of dish you are using. Drifty LNBF's can cause a loss of signal at night but also marginal signal could cause it as well. All Asian KU sats that I looked at are linear and use both low and high bands so it's necessary to have a universal LNBF.

Are you using C band or KU band? what dish size do you have?

The Indian ku satellites have very tight footprints and I am surprised you can receive them at all

We can work on your Indian TV problem but first we dance!!!

Ok, do they fade out or just go off at the same time?

Hex,

I hope that I am not convoluting the issue here, but I have run across this once with a DN subscription. I had a Dish Net Twin DPP LNBF on my subscription quite a few years ago. When the sun came over the horizon, the signal would steadily and quickly crap out on one of the two sats (either 110 or 119 cannot remember which one). Until that one sat went completely dead and it remained dead until late at night when the temperature dropped. Eventually, it came to the point where the signal remained dead at all times.

Do you think your situation could be temperature or humidity related?

Although you obviously do not have a DN subscription, an issue related to temperature or humidity is a very likely cause. Try checking all your cable ends for moisture entry or corrosion first.

Then try chilling your LNBF with dry ice when it has failed in the heat of the day.

These are just ideas, simple things to test.

Good luck in figuring this out, sometimes these scenarios are really illusive. What I present to you is simply an idea off the top of my head.

The only thing I've ever noticed affecting any of my LNB's was rain. BUT, it could be a suckout on the coax connector. The center conductor contracts when cooled and loses the connection. When things warm again , it expands and remakes the connection. Back when AT&T paid me to track problems, I would always check the timing and the weather when it was a reoccurring problem. Something would go off at night, a trouble ticket would be put in. A tech would check it the next day and find no problem. I would flag that area to have a tech roll at whatever time something happened.

Hex, this is great advice my experience in Manila was that humidity was a huge problem with water penetratin into the cables if the plugs were not well proofed. I used to use silicone over the plug and exposed threads.
Assuming you are viewing 83 and 93 west your skew offset will be around 60 & 67 degrees counterclockwise facing the dish from behind the LNB. A few degrees out makes a considerable difference on the signal and quality.
It could also be that Insat satellites reduce output power just prior to their to their solar panels becoming eclipsed
