A simple question. I have a FOxtel dish that needs to have a 10700 LNB on it instead of the 11300 it has now. Will any LNB fit it or am I looking for a certain type model or brand?

Thanks in advance for any replies.

Look Here -> |
Any LNB(F) (LNB with integrated feed horn), which has a local oscillator frequency of 10.7GHz (10700 MHz) will be perfectly adequate.
Having said that, buy one of the better known brands, such as MTi, Strong etc.
There are many on E-bay to choose from at very low prices.
Don't forget to adjust the skew correctly. (If you don't know how to do this a simple SEARCH will lead to posts explaining how.

G'Day Cobber,
To my knowledge all those advertised are suitable. Just depends whether you need a Single / Twin / Quad Dual output.
If you have a Twin Tuner, more than one box to feed, then you need to upgrade to Twin or Quad.
Apart from driving motors, you may also need switches for the more elaborate setups.

I only have a single box to feed and I will look for the "Skew" topic.
The only LNB I have seen so far have been "SHARP" brand
I'll keep looking.
Thanks to you both for the heads up.

G'Day Cobber,
Skew is the relative angle between the transmitter and receiver antennae.
It is a function of the Azimuth Viewing Angle from your location as well as any preset angle on the Satellite.
Unfortunately Optus, in their wisdom, have set their Satellites with a Skew that is ~40 degrees different to other Satellites in our Sky.
Skew is set by rotating the LNB in the holder, and for the Eastern States is usually with the downlead at 7 O'Clock, whereas for western, about 4 O'Clock.
Kindest Regards, " The Druid ".

Sharp LNB's are fine.
Actually, they are the standard brand of LNB installed by Foxtel/Austar.
I live in NSW near the east coast. If I replace the LNB at the same angle etc it should be ok, I hope.
"Sharp" is ok. Excellent. Thank you

It's merely a matter of twisting it in the bracket for maximum quality on your STB.
Be aware that there are two peaks 180 Degrees apart and that you can peak a H or V transponder 90 Degrees from the correct position if input data is incorrect.
Always use the position where the cable is pointing down to minimise water ingress.
eg: 12407 is usually V, however you could peak it as H, 90 degrees out.
To put it in a nutshell, for line of sight, both Tx and Rx antennae must be in the same plane for maximum.
Kindest Regards, " The Druid ".

It should be close.
To adjust for the best result, you need to be able to see the signal quality graph from the decoder on a screen, then turn the LNB in it's holder in tiny increments until you get the highest signal quality/strength reading.
Note, if the LNB can be moved forward/back in the holder too, you may need to optimise that position in the same way as skew, but this time pushing/pulling the LNB towards and away from the dish.
Hope this helps.

Thanks for that Druid.
Thanks MTV
