how to receive 4.8e-7e-9e on toroidal?

[pidgey]

hi, im using this toroidal wavefrontier t90 and im trying to receive 4.8e, 7e and 9e, but being too close i can only receive either 4.8e and 9e, OR 7e only, because the lnb dont fit, i wonder if i need some kind of special lnb or if anybody managed to fit 3 lnb on such close distance.

In theory if i stick one lnb on 8e position i should be able to receive either 7e AND 9e, but im loosing too much signal and i barely receive from one of the two satellites.

You must use slim feed lnbs like inverto , just make sure the lnbs are not near the arms to front dish . with small feed lnbs yuo can have a space 1.5-2 degrees .

good idea, thanks!

i just need some different holders i guess, the original one for wavefrontier are too wide for that kind of job

For example like this, I had it on T90 some time ago, those are quads

Closer encounters of 2-3 degrees ...

Hi , with original holders is not possible , You can use an upper bracket with 2 plastic clamps for 40 mm electric tubes like Fisher art. 04609 (if available in Your contry) or similar .

Interesting solution. How could you manage to run all those LNBs without wires at all?! Joking :thum: I think, that original T90 LNB holders should go directly to trash can and should be replaced ASAP by better ones which allow to adjust each LNB very precise and in all dimensions including UP and DOWN.

Original holders are suitable for standard solutions and average users ...
If a "fine tuning" is needed it' s necessary to use alternative sistems , manual-skill and passion ...

manual-skill and passion ...

I see you have lots of passion! How many man-hours did you spend on the roof to tune this? Is that system has good wind-resistance?

Fine tuning from my point of view never ends , there is always something to modify or improve ...
Fortunately in my zone there aren't strong winds ...
