My neighbour Lex swears by his Eagle Aspen lnbf for ku band. I found an awesome deal on e-bay and will test it out on my 4' Channel Master.

EAGLE ASPEN DUAL OUTPUT KU-LNB

This is a replacement INBF for the Satellite Dish made by Andrew, Channel Master, Primestar and Globecast 70E, 75E and 84E Series Antennas. Replaces all single and dual output LNBF.
The Eagle Aspen is a twin-switched 270 KU dual output LNBF meaning each port is capable of voltage switching (13 Vdc = Vertical Polarization & 18 Vdc = Horizontal Polarization), from the receiver.
The advantage of this type of LNB is it no longer needs a mult-switch splitter for two receiver installations, simply run a coaxial cable from the LNB directly to the receiver.
