On the GEOSATpro SL2-Bullet LNBF box, it is billed as the "Smallest High Performance Dual Output LNBF in the World". Someone other than me might be a better authority to judge that claim. But look at the pictures.

In the attached pictures, there is a KUL2 dual on the upper left, the GEOSATpro SL2 dual on the upper right, and a Fortec FSKU-v UNI single at the bottom. The GEOSATpro SL2 is tiny. It is the size of a single and the feedhorn is no larger in diameter than the 40mm feed mounting.

Specs:

Standard, Linear Polarization

Reception Frequency:
Ku High Band

RF Input:
11.7-12.75 Ghz

L.O. Frequency:
10.75 Ghz

IF Output:
950-2000 Mhz

Noise Figure:
0.4 dB (typ)

Gain:
60dB (typ)

After winning two of these LNBFs in a SatelliteGuys contest, (disclaimer) I have had the opportunity to try out this unit for about two months. I am really happy with the performance.

As a comparison with the other 0.4 dB NF LNBFs I have, it does as well or slightly better than the others at about half the size. I believe this is due to the 60dB gain spec.

For people using dishes with a single tubular LNBF mount, you know how the imported dishes can be a little too flexible. Low mass and small size of this LNBF should be a benefit. I don't think it will be prone as the others are to catch wind, flexing the mounting under their own weight.

Also, for people deploying multi LNB dishes, or those who have use for a monoblock, you can place these LNBFs very closely together if need be. Accordingly, this unit would be an excellent pick.

Looks good, the same size as the single output version. Would be great for toroidals :)

Those look very nice. I have the single output versions and work great. The duals are more versatile :)

Any thoughts on whether this might work for sats 2-degrees apart on a 1M dish? I'm thinking to put up a second non-motorized dish this summer and if I could get G18 and AMC21 on one dish that would be king!

There are threads on it in the main area

a 1.2m....very possibly
a 1m...highly unlikely

found one

Thanks Iceberg, I've been away a long time so I'm slowly catching up on threads. Any dish that I add would be a max of 1M so I'll rule this out. I'm also not handy enough to do customized modifications. It would be nice to have G18 and AMC21 together but it's not a huge issue considering the short time to motor between the two.

Nice write-up Guapoharry, I just might have to try one of these out:)
