There is no such thing as a "good" or "ok" split or splitter!
When your Astro B.yond box needs to tune to a high frequency signal on Measat 3a to receive HD it sends a 20Khz "tone" to the LNB, this switches a circuit in the LNB called the "Local Oscillator". At this point the LNB is only capable of receiving high frequency signals so any low frequency signals such as all the SD channels on Measat 3 are no longer there or "on the wire". The same is also true when switching between Horizontal and Vertical polarities, currently Astro only uses Vertical if ever they use Horizontal I am sure that a whole load of us will find new dish alignment problems.
Even if you only have SD Astro and not a B.yond Box then you should still not use splitters, each splitter halves the signal. Thus increasing rain fade significantly.
Try my test of trying of watching HD on B.yond and SD on your old box see what happens! As a professional in this industry for 20 years it shocks me that installers still do not understand DiSEqC and use splitters.
Splitters should only be used for one thing, throwing at the installer who tried to fit it!
I did a scanned on M3 & M3a before and found both H & V signals. Not sure about now? If you are working on the tall office up in down town KL perhaps you have the latest info on this matter.When your Astro B.yond box needs to tune to a high frequency signal on Measat 3a to receive HD it sends a 20Khz "tone" to the LNB, this switches a circuit in the LNB called the "Local Oscillator".

What would be the best solution for MDU customers (condo) if splitter is not recommended for sat tv?
