Morning Friends.

I have the following Lnb on my KTI currently.(Specs below)I would like to get something that offers both c and ku in one.I have some Questions down below.

C-Band Single Cable Solution LNBF
Stock Number: 310002
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
Environment
Operating Temperature -30°C ~ +60°C
Storage Temperature -55°C ~ +80°C

1) Is this ^^ a good Quality LNB?
2)I allways though that having a lnb that does not sit behind the feedhorn reduces signal,due to the signal bending(curving?) around to meet the Probes in the LNB?
3)What LNB will be prices ok,and offer good or perhaps very good reception in both C and KU reception?

Thanks! :)
