[QUOTE="karism, post: 388223, member: 251660"] Thanks for the reply Bud! Ok,i have another LNb (this one came with the 3m) Which one of the two would you say is better.I have learnt,its not just about the gain,but the noise as well? Item Description LNBF C-Band single cable solution 3.7 - 4.2 GHz Specifications Manufacturer MTI Model Number AC15-2CV Input Frequency Range H: 3.7 - 4.2GHz V: 3.7 - 4.2GHz Output Frequency Range H: 950 - 1450MHz V: 1500 - 2000MHz Connector Type 75Ω Female Connector VSWR 2.5:1 (max) Local Oscillator Frequency H: 5.150GHz V: 5.7GHz Frequency Stability ±1MHz (max) @ room temp. ±2.5MHz (max) @ -40°C ~ +60°C Frequency Phase Noise -75dBc/Hz (typ) @ 1kHz @ room temp -93dBc/Hz (typ) @ 10kHz @ room temp -105dBc/Hz (typ) @ 100kHz @ room temp Conversion Performance at Room Temp Conversion Gain 60dB (min) Gain Flatness ±5dB (max) over operating band ±1.5dB (max) / 36MHz Noise Temperature 25°K(max) Image Rejection 40dB (min) Cross Polarisation 20dB (typ) Power Requirements DC Current Consumption 150mA (max) Operating Voltage 12- 24VDC Thanks!
