Brilliant innovation
I think Vicwa or a member here last year posted a better way of going about it by making the arms adjustable. You cut in the middle or near bottom edge. Add a thiinner rod which will have a bolt lock ie a contraption like the prime focus elevation adjusting arm.
Freq a question how does let's say apstar 7 lnb get the channel of thaicom in a motorised set up do you have to set it on decorder or how have you set itNo I didn't touch the lnbs perhaps adjusting them would give better results
Very smartly done indeed. I missed the discussion around your post. And your finding also was that the extension improves signal?Yes, it was me and I can say I'm smart on it.

In your dish settings on the decoder, set a single lnb accross the sats as picture shows. In this case "lnb 6" then move the dish from IS 20, apstar, thaicom etc.Freq a question how does let's say apstar 7 lnb get the channel of thaicom in a motorised set up do you have to set it on decorder or how have you set it
The setting is exactly what I thought. Thanks for info I think motorising a dish is the way to maximise the useIn your dish settings on the decoder, set a single lnb accross the sats as picture shows. In this case "lnb 6" then move the dish from IS 20, apstar, thaicom etc.

Moving the dish can be done manually every time you need to switch sat or automatically by dish positioner . once the position is saved, the positioner will automatically move the dish there when yo switch sats.
Note the single lnb accross multiple sats will only work if no dielectric plate is required accross all those sats and lnb skew is same.
Or dielectric plate is required accross all those sats and lnb skew the same . Otherwise you may need to install a parasite lnb say' lnb 4" with the dielectric plate inserted and skew set differently that's how I nab 57e C band on the Motorized set up.
I made the same extension on holder for two of my dishes.Yes, it was me and I can say I'm smart on it.

Wishful thinking 😉 ...
Some decoders easily indicate 100% eg Qsat models. Esp on strong frequencies. On either Intensity/ strength or Quality.
OK..but theoretically you can't receive 100% of what is transmitted ?Some decoders easily indicate 100% eg Qsat models. Esp on strong frequencies. On either Intensity/ strength or Quality.
Yea you can use that one. Problem with it is; all lnbs Will be parasites and there will be no primary (central) lnb such that the sweetest spot of your dish will be wasted..Can one modify lnb holder like this and be used in a motorised setup and have 3 lnb arm supportView attachment 866383
Also not adjustable, in addition to parasite effects.Can one modify lnb holder like this and be used in a motorised setup and have 3 lnb arm supportView attachment 866383

I think received signal quantity is measured in decibels (db). db being a geeky measurement unit, manufacturers traditionally resort to proportions that laymen users like you and me can understand. The percentage.Interesting question. What does the percentage mean? Percentage of what? Obviously its not percentage of what was transmitted because what was transmitted covers a large foot print and one decoder can't get it all. I think signal strength means percentage of the maximum signal amplitude the receiver expects from the lnb. The higher the radio waves the stronger the signal. Quality refers to the digital data the receiver is able to understands (decode) as a percentage of the data it has received.

Now a decoder manufacturer programs a certain yard stick against which received signal quantity is measured. Say 20dbs = 99% 12dbs = 60% and so on.
when you receive 12dbs, your reciever will indicate 60% which is 12 against total 20 it is expecting not necessarily the practical maximum.
More like your phone battery; when the battery potential drops to about 2.5volts against the full 5v the phone can be programmed to show it has 50% battery remaining. A cheap Chinese phone could be programmed to show it's 80% full when you only have 2 volts out of 5volts. If you want 100% for 1 out of 5volts, Chinese will give you just that.
As for 100% never shown. I've realized strong is programmed to show only 2 digits for signal/quality indicator (they don't expect you to get a 3 digit signal strength/quality with their low sensitivity tuner anyway). 100 being 3 digits is a no go zone.
Quick Vocabulary Reference:
AMP Hour is a unit of measure for a battery's electrical storage capacity. The standard rating is an amp rating taken for 20 Hours.
Voltage represents the pressure of electricity. Some applications require more "pressure," meaning higher voltage.
