on the same forum i came across the following experiment that i want to try using a standard polyethylene chopping board:
plate-3-jpg.42480

apparently it has some astonishing results for c-band on Mini-Buds-doubling or tripling the signal strengths on some sats..

Man ! C band solutions are hardly ever universal. You'll try a trick on a tp and it'll work like charm. Another person will try it on another location on a tp and say you were lying. That's why there is no universally accepted best cband 'best lnb'

true that.in that thread two chaps had excellent results.others had mixed results.but i guess the fun in ASAS is experimenting and trying to see the outcome.the thing is- if an FTA enthusiast tries something and notices that there is a signal improvement, most folks,being no physicists,cannot explain it.even the originator of this thread is asking forum members to try and explain to him,based on scientific facts, why there is an improvement after using the modified teflon.what follows are more questions and theories-e.g. the dielectric used can be 6-8 mm,it must not be smooth,which is the best dielectric materiall,what is the best length to protrude off the scalar,how far does the modified dielectric go inside the throat of the lnb and so on.a phyisicist,or satellite expert,could give a scientific and definitive answer,after carrying out a methodical research and analysis so that in the end, there can be a universal and definitive conclusion that works across the board.

You see, propagation of low frequency radio waves is affected by a wide range of factors.
Take for example FM radio reception which at times can be quite funny. You may only be able to receive good signal by putting the aerial into your mouth or by placing the radio aligned to a particular direction. Or by letting a baby carry the radio. You can't explain why and it may not work for another person. The lower the frequency the more misterious it gets. Remember AM radios? Tuning those were even harder. And short wave radios (some only work at night. Atmospheric pressure and temperature is also a factor). Tried setting up a VHF terrestrial TV aerial? Your neighbor's might work while placed facing one direction but yours might need another direction.

Apparently the higher the frequency the more predictable wave propagation behaviour becomes. So ku is better understood and ka even better.

Now back to that guys experiment. You could find, a low frequency interference was coming from one side of the dish. Placing a huge plate like that was partly blocking the interfering signal thus improving reception. If you try it elsewhere without the interference you won't see any improvement only good signal blockage.

Why must the plate be rough? Again just theories; Rough surfaces are known for irregular reflection hence scattering off the interfering signal? Rough surfaces have more surface area and that got something to do with "absorbing" good signal? Who knows.

Just my thoughts.

Hahaha...very funny..anyway the theory given was that a smooth surface created standing waves,in phase,on the plate surface or dispersed anti-phase standing waves(whatever that means).truly ASAS sufferers are borderline crazy.i also read about adding a scalar to an inverto ultra :

As they say-There is a fine line between hobby and mental illness.

Satellites.co.uk, satguysus.com tvrosat.com and other foreign satellite forums are very rich in info. They don't even discuss hacked channels, power vu and stuff infact its banned over there (even discussing boxes like Freesat is forbidden) But the info in those fora is still amazing

I have accounts there..

These guys live in the west,with higher income levels-so they can afford better toys.They also have access to alternatives like IPTV and they have better internet infrastructure.And i think most of the satellite beams favor them- just look at for example 28.2 e.Based on all these factors, they may not have such a high need for hacked things(though many brit football fans are forever whining about the high skysports subscription charges).Having said that, i personally find there is a thrill that comes with watching channels that you are not supposed to watch in our neck of the woods(africa).In my thinking,the west was built using grabbed resources from other parts of the world.so i have no qualms about grabbing prohibited TV signals or even using pirated software.I see it as payback for our 'grabbed' natural resources.And even today they still continue to grab our natural resources(after colluding with our 'leaders' of course).the best example is that of coltan and tantalum,found in the congo and used in all the laptops and smartphones of today.the west pays very little for these minerals.so watching hacked channels is a way of 'balancing' their theft.

You right. Even if we watched cumulative 10 billion hours of CNN it wouldn't be able to repay free labour our ancestors provided for free during 400yrs of slavery. 😎

Brother Vicwa my patience runs out after every 15 minutes, whenever waiting for hellobox to wakeup from slumber. I guess knowing Freesat does it in 2 minutes accelerates negative patience persistence.

The first blazing was 30.....minutes, but this morning it blaze after 2 minutes.

Freq sir! r u in kenya? What size of the dish n lnb type? 10887H as troubled me for several weeks.

Am using a 6ft pf. But it's targeted at 3W. 7/5e is a parasite. Lnb stargold fuji. Location Nairobi.
