What's the use for this LNB?
Are there any satellites transmitting in that range? I thougt it was for uplink?

And if so, any TV or radio-signals in any format?

Looks like a VCXO crystal on the side, but only two pins are soldered to the PCB (1 - V.C and 14 - Vdd) ? ... bend over

Not much going on currently

As CH says, not much receivable in N Europe. More beams centred on ME and Africa.

Thanks for the reply.
What I can make up what they are doing there is receiving the normal Ku-band frequencies with this LNB?
Probably just to prove they work, but if there's nothing to receive on 13.75-14.5 GHz no use on buying it.

The 9 GHz LNB on the other hand can be used to receive QO-100 on Es'hail 2.

I've been scanning at both ends of the Ku band for a few years, it's quiet if looking for stuff on the arc.

The BWEI LNBs appear to have very poor image rejection so will also receive the standard band these were discussed in one thread. However there are some reports of TV activity:

07.0°W Nilesat 301 - Satellites Community

Using BWEI LNB L. O. :11.83Ghz (12.78GHz-13.28GHz) (opening scanning limit on crazyscan), I was able to receiver 2 frequencies on 120CM dish.13572 H 27500 DVB-S 5/6 (LNB 0° skew) Nilesat promotional channels.13553 V 27500 DVB-S 5/6 (LNB 90° skew)…

I thought that I'd posted these at the time (May 2021) but can't find it now. These are plots and pictures from the testing period. The LNB was an SMW 12.25-12.75GHz SMW PLL with an 11.3GHz LO. The dish was an Prodelin 3122 1.2m offset. Blank screen No…

The only thing that seems to be visible most of the time here is the beacon on 13401V on Turksat 5A. The attached plot shows it together with transponder noise for unused but enabled TPs. (Modified SMW 11.75GHz LO PLL LNB, 1.2m dish).


If you want to receive QO-100, it's better to use a standard PLL LNB some of which work fine at 10.5G. The 9G LO ones are mainly DRO.

IIRC long ago in another forum, sidelobe reception of Ku-band uplinks was reported in that 13.75-14.5 GHz range, by someone near and pointing to an uplink station. Maybe some stuff can be received that way, if you are outside the associated downlink footprint.
