Horizontal/vertical transponders

[odysseas1991]

With a setup I am working on, I have found 98% signal quality on all vertical transponders on hellas sat. However all the horizontal transponders do not have any signal. I have noticed along the horizon of the dish that some tree branches are in the way. Is the problem that the trees affect the horizontal transmission and not the vertical?

Re: Horizontal/vertical transponders

is your box tuner working good? because some tuner's problems affect the signal polarity and allow to receive only one side or maybe it's a matter of broadcasting area.

You could try and turn the LNB through 90 degrees and swap the polarity via the receiver setup.

The reciever is perfect as these same exact transponders worked about 2 weeks ago. The only thing that has changed since then is that the trees have grown leaves horizontally...

I could try that but I dont know if that will effect all the remaining satellites as it is a motorised system and it has taken me ages to tune in all the satellites to work with 90+ signal quality.

Re: Horizontal/vertical transponders

Basically, all I want is confirmation/clarification that transponders with horizontal transmission can be affected by trees going along the horizon whereas on the same satellite the vertical transponders work perfectly with 98% signal quality?

I doubt this can be blamed on the leaves as they normally grow in all sorts of directions. I'll be interested to see if you get a qualified technical response though!

Bad weather does not affect satellite reception much. ... But your eyes do not get any further than one of your trees that have grown so much it is now in the way... Can't be a coincidence. I've had the same problems with myDish

I think that could cause the LNB converter.

Is there an echo in here?!?

I agree that a lot of growth could affect the ability to block the signal, but I was saying I would be surprised if it affected only one polarity?

LOL, what the heck...hussain3334 are you having a laugh?

Easydigital, its not about bad weather, the issue is, I had to cut some branches off the tree to get ANY signal at 39e in the first place. I come back 2 weeks later and there is practically no signal on the vertical polarity and none on the horizontal. I readjust the dish to get very strong signal on the vertical, but the horizontal nothing. What do you mean by eyes? :S

Skytec, what is an lnb converter and what do you mean?

Redhezuk, thats what im thinking but I think im just gonna chop the tree down and see what happens...
