WS International TechSAT Stealth Bullet U1 Universal Single Ku Band LNB / LNBF



Universal Ku Band LNBF


The newest Universal Ku band LNBF from WS Interntional!!

A high gain of 70dB & Low noise figure of 0.3dB!  Don't let this little LNBF fool you.  You will get the most stable signal, the lowest noise & excellent signal reception.   Excellent to use with Amazonas!


Includes 1 piece 23mm to 40mm adapter


We tested this new TechSAT STEALTH BULLET U1 LNBF on several satellites.  We put it up against our ESX521U-FE, our ESX521-FE, and two other LNBFs from our competitors.  What were the results?  You may expect a much lower signal reading due to the fact that this little unit does not have a large feed horn or scalar ring.  This was our thought at first also.  But to our surprise, we received a very good signal quality with an extremely low noise reading.   The signal quality was just as high as our ESX521U-FE & ESX521-FE, however, the signal intensity (noise) was much lower.  Anywhere between 5%-13% lower on the different transponders.  We also noticed a much more stable signal when compred to the competitors LNBFs that we had at our disposal.  So over all, not a bad performance from a small little Ku LNBF!!
