possible to connect to below horizon satellite?

[JustDooIt]

Living in California USA, trying to connect to 52.5E Yahsat 1a. I saw that this is below the horizon from where i live, does this mean i cannot connect to it?

Welcome to SatelliteGuys JustDooIt !!
That is correct. You must have a direct LOS(Line of Sight) to the satellite.
If you can't see it with your dish you cannot receive it.
52.5E is for sure way out of LOS for Cali.

If you could raise the dish high enough, would that help? I'd imagine it'd have to be on a tower.

Yes in theory, but the tower may have to be tens, hundreds or more miles high. I remember someone here showing how to do the math at one time, it was an interesting computation.

52.5E isn't "below the horizon" LOL It's on the other side of the planet. You couldn't see that from a tower in space.

might be a stupid question, could you detect an under-the-horizon satellite using a temperature inversion/troposheric ducting?

Think you'd have to be very very lucky for it to happen. There was another thread a while back where some calculated the height you'd have to mount your dish to see a satellite 2 degrees below your horizon. (IIRR almost low earth orbit range)

Is this the thread? http://www.satelliteguys.us/xen/posts/3446161/

In theory you can pull a signal from below the horizon as the gravity of the earth will bend the signal slightly. But the negative to that is you are trying to get that signal through a lot more atmosphere and all its interference. Satellite signals are not good at terrestrial trips.

More likely to refract a C-band frequency than a KU band. Back in the analog days I remember talking with installers in Alaska that would pull in satellites calculated to be 4-5+ degrees below the horizon. The skew would be wacky and they would need to adjust frequently to track track the polarity shift in the refraction.

mikekohl has a lot of satellite experience in the Great White North. Maybe he will weigh in and tell us his installs!

nope. Think it's a lot earlier. But I'm unable to find it.

What channels are you wanting to receive 97w ku would work for you or 30w.

 

[KE4EST]

He is looking for Afghan TV channels.

 

[danristheman]

Don't they have some on 97w ku?

 

[JustDooIt]

thanks for the help everyone and sorry for the stupid question was foolish of me to actually think it'd be possible

Don't they have some on 97w ku?

indeed they do, very little though. Literally all the channels I want are on 52.5E lol, woe is me..
